I hate tooting my own horn, but check out PageRankBot, recently mentioned by seobook, Dan Thies, Andy Beard, and Search Engine Land. Its a free tool used to optimize internal link structure to manage supplemental results.

Does it make the cut? You decide.

Another shameless plug: I recently created a rank checker like the SEOMoz one - the difference being that there is no limit to your searches.

Good list. The ones from WeBuildPages are pretty good. Halfdeck, your tool also looks useful.

Please Google on the HitTail application to see if it may be worthy of the top 15 list. I don't know what should be displaced, but certainly a tool that lets you grab a top position every time on topics relevant to your site where qualified visitors really are searching should be considered. Thanks.

David,
I tried to look for the tool on your site to check it out but didn't see it. Could you point me in the right direction?

Thanks!

Hi Halfdeck and Mike Levin.
Those are two good tools as well worth noting. I'll likely do a larger page of tools to follow up this one because there are so many new ones built within the past 6-9 months worth a mention.

Halfdeck, that is a great tool. I have a few clients that need some serious work in internal link structure. I'll definitely check that out more this week and use it on their site to see what improvement it can provide. Thx!

Are there any other keyword tools besides Overture and Google Adwords? This seems like a fairly important part of the process, and the 2 current offerings leave much to be desired.

Hi SEO Guru. Thanks for stopping by. Sure, there are a bunch of keyword tools that give you lots of options and data. Danny Sullivan pointed out a good resource list of just keyword tools in a comment to our tools list on Sphinn a couple of days ago. Here's his list of keyword tools:

Keyword Suggestion Tools

The SEOmoz rank checker is elegant, but the five keywords per day limit is a serious drawback in my book. I prefer to use either this checker from Mike's Marketing Tools: Mike's marketing Tools (Though I've had some problems with the accuracy of Yahoo results on that one) or this checker from SEO Chat : Entering the Captcha text for every search gets a bit old, but the tool is free and seems to be fairly reliable.

Wordtracker still rules if used correctly. Mike Mindel, Co-Founder and CTO, has again revealed himself as a quiet genius with a production curve for their algorithm improving in leaps.
I wouldn't doubt a hi-5 from MAtt C, for what this guy puts out free! The paid, and the new Gtrends helped 10,000 newbies leave the cocoon in full flight.

Thanks for posting this great list. Currently trying out a few of the sites.

hey... that is a great list. i was going to write a backlink checker for personal use... great to see that I dont have to!

Hey Brian thx for this excellent list... how about adding a list of some backlink and meta tags generating tools...

Hi, can you explane more clearly about the tool bar. And get more for us. Thanks

Hey, a very good list you supplyed there. I wish me souch a cool list for my pcboardstyle xp engine to have an overview whats going on.

Yours

Knut

Huh? You listed about 3 tools that are actually useful to anyone.

Density?
Rank checkers?
Analyzers?

You must be kidding me.

How about your brains? Why do you need these tools anyway? LOL

Funny stuff people. The ONLY tools needed is your brain. The zenu thing. Google stats or any stats or your logs.

ALL the rest is a waste of time for you and your clients. Period.

I often wonder when the industry will actually gets a brain.

Brian - Great article! I would like to add another useful SEO tool. We put together a collection of popular SEO tools all on one screen, so you could type a single URL and instantly get readings on traffic, related keywords, keyword density, pagerank, PPC etc. It's at Software Projects - simply type the domain you would like to explore at the top.

Hey Doug Heil,

If you don´t like the list, simply colse the breowser. What is the meaning of wasting your time doing dumb comments? You are not using your brains as you said.

Congratulation Brian, nice list! thanks for that

OMG that tard has struck again. Whats up with Doug? Jesus Christ I've never seen such a bitter individual. Your brain cannot aggregate data on the level that some of these tools provide. Your brain can't possibly click enough URL's, parse 1GB of content, and make sense of it in a few minutes.

Hi Doug, Thanks for stopping by but I'll have to agree with Tony and Bruno here. There is no way that one's "brain" can comprehend, parse, and display data on any level even remotely close to what these SEO tools can do.

It seems like you're bitter towards this industry for some reason, but we just tried to list some tools that some people might find useful, especially for people that don't have computer brains - which it seems like you must have. So congratulations on that! ;-)

Thanks Brian!

I have not heard of a few of these. Always useful to see what tools others are using.

Thanks for this great list! It's always great to see this kind of *stuff* organized like this.

I'm under the impression you found them in the end. Please excuse my stagnant illogical web site :P If not, they can be found at: SEM Labs I had a bit of trouble with the IP being blocked by Google, but it has been OK the last few times I used it.

That's a truly awesome list of sites. Most I'd heard of but a few are new. Thanks for the info!

Thank you for sharing this very usefull list. I also like Digg Page Rank . Very handy tool!

Thanks.Perfect.

Hi Brian,

Greetings from Italy. Thank you for the list, I thought some of the websites also mentioned in comments were very interesting.
Now it's time to choose the ones to adopt to optimize my newborn site.

Thanks,

Andrea

To the last few posts (Kent, Scott, David, MidasEffect, Adsensor, gohans, and Andrea) - thanks a lot for stopping by and for taking the time to comment on the SEO tools list. We really appreciate it!

Since we have a backlog of tools and resources that are mostly free, we'll start posting them. I think that putting aggregated information together like this SEO tools list is excellent for those who don't want the high cost of some proprietary SEO analysis tools. Hopefully this list will help those wanting to improve their site(s) structure, backlinks, keywords, etc.

Thanks again!
Brian

thanks for the great stuff...

good to know,thank you so much

Thanks for sharing this with everyone.

Some nice tools that I've not heard of before there, thanks. A new tool that provides a lot of very handy information is: Website Grader it's extremely useful but according to the site it won't stay free for long :(

Thanks for sharing this great collection of tools, I usually use seolog and webuildpages tools, others are great too.

I use IBP/Arelis at the moment but wondered if you've considered adding in webceo, theres a free version thats pretty comprehensive and does a lot of the mundane SEO stuff!

Hi Mark,
Thanks for the recommendation. Perhaps we'll do a larger, extended list with some other tools such as the free version of WebCEO. 15 SEO tools is really just the tip of the iceberg.

Some of your bigger clients may want to know how much their site is worth. Anyone who is in the business of selling websites knows, that in the end it is worth what someone will pay for it. Outside of that though, this little tool gives some indication of your site's value: DNS Scoop . It may not always be accurate on some of the stats spat out, but, the algo it uses must be darn close. Sometime back, I checked to see how much the website shopping.com was worth, and that tool gave a value of $600mil. Interestingly enough, eBay bought shopping.com for somewhere around $620mil. Have fun using this tool!

Great list, I hadn't heard of a couple of those before. I just released a free tool some of you may find useful. It helps you find old sites that have been abandoned that you can try to buy for very little. It uses your dmoz category to get a list of sites for your niche and then it finds which of those sites haven't been updated in a long time (abandoned). Finding old sites to buy

Thanks for that list. Some of these tools I've never heard of (but they look great never the less). Obviously Google analytics and Overture keyword tool are the more famous ones but I think I'll be giving a few of the others a try.

Those are really good resources thanks for sharing! It is always good to know.

Limitless ∞

digpagerank.com is a great tool, though perhaps now obsolete seeing as Google haven't updated PR for ages!

Someone already mentioned digpagerank.com, sorry for the duplicate info.

Interesting that some firms made this list multiple times - proof positive that a great way to promote yourself is to provide useful tools for free

Actually I am using only 2 things from the list, but my SEO is nicely effective anyway. These 2 things are Google Analytics and Google Sitemaps.

I really don't see any advantage of using other tools.

These are nice, but here is more: Aaron Walls SEO Tools . Cheers! Alex

Thanks for posting this. I used several paid SEO tools but this is much better since I can opt for the free versions and save a few bucks.

A tool that I use on all my sites is SEO Trail . I think it is worth a mention. "SEO Trail is a search engine tracking tool and a social networking tracking roll-up that monitors how well a site is performing across various indexing and ranking platforms."

Thanks for this. I already use the Google tools but did not know about iwebtool or ranks.nl. Now I use them several times per week since finding them through your post. Thanks again Darren

I am a professional SEO consultant for UK companies. One of the best tools for working out hiw your SEO work is progressing is Web Site CEO . Not only is it free (you can pay £100 pa for updates which I do (only software I think I have ever bought))but it is an accurate all round resource for page links, rankings and keywords.

Thanks for posting this. I used several paid SEO tools but this is much better since I can opt for the free versions and save a few bucks

Hi As everyone know how important article submission is, I am using Artemis Pro. A fantastic tool which submits articles to thousands of publishers and they all go clean without fail. You should checkout this nice tool artemispro.com, on top it`s not expensive at all. I wanted to be cheeky and ask for my money back guarantee..but I honestly think its worth my bucks. Rajesh

Hi Rajesh, Thanks for visiting. I think article submission has its place in SEO, albeit we don't use article submissions or article repositories necessarily as an "SEO tool," which is more the jist of this post.

SEOtracker, I'll take a look at the SEO Trail tool you posted. It looks like a mashup of several other free web based tools, but I'm a big fan of aggregating many tools into one location for easy use/reporting.

Jan the designer, I thank you for your opinion. I really think all of the other tools and deciding to use any of them really depends on the webmaster/SEO using them. The competitive landscape and other things like keyword research or robot spidering might also determine their use within any site owner's SEO toolbox.

You've got to love free software! I do have to admit that I do actually use Nemeas to promote my website, but i'll certanly be using some of these freeware tools! They're fantastic!

Thank you for bringing them to my attention!

Hi there!!

Actually i am a new seo webmaster and need to know about the varios tools and i got many of them through your article.

Thanks a lot..

i will love to hear from you on my blog as well...

hi all, thanks for the info, i use the tools from iwebtools alot but they do fail at times

It seems that not all of the tools listed are still free...

eg: Strongest subpages tool

quote:
"No Longer Available to the Public. Only available if you purchase the Training Videos"

Still it was a good thread and some interesting info here :)

James.

DoFollow Searcher Tool that allows user to search through millions of blogs for Do Follow attributes that allows links on comment to be counted as a backlink and followed by spiders. Dofollow Tool

has been down for some time now, anyone knows the fate of that project/service ?
I heard that its only offered to the paid yahoo customers nowadays...

Great Tools, thanks for sharing Brian.

Thank you so much for the top 10 SEO tools, yeah I know very few of above stated sites, now I got to know other sites too that I missed before. Thank you once again.

Check this out: smartpagerank.com and domainpagerank.com. I know a lot more better seo tools.

Great listing. Found some new tricks to add to my bag. The SEOMox Tools and SEO for Firefox have been staples in my arsenal for quite some time now. Thanks again!

Very nice list indeed. I use Google Analytics a lot but I also use another great tool that isn't mentioned - DomJax. It is a free domain name register with a lot of cool SEO tools in it.

Theres alot of really good quality links there, but what about the black hat side of things ?

Maybe there should be a section entitled 'the darker side of SEO' - enter at your own risk ;)

good tools :D nice greets all !.

Brian, great post, I hadn't even heard of some of these sites! One of my favorite SEO analysis websites is Website Grader. This site gives you a good general overview of your SEO and also gives you a mark out of 100.

Maybe there should be a section entitled 'the darker side of SEO' - enter at your own risk ;)

nice document, thanks for seo tips.

Excellent list, some that i haven't come across but are great tools..

I recently installed the SEO Quake toolbar and have found it to be good for giving a quick snapshot of what's happening on a site. I will definitely have a look at the tools mentioned here. I have already checked some of them out. :)

I currently use Google Analytics but had no idea about all these other fantastic tools available for free, thanks for sharing ;)

Some great tools on this list. You might want to use a link checker, the xinu link is broken. Seems the site is gone.

Great advice, even from the comments. There's some great tools and tips on this page.

thanks for your post; can you explane more clearly about the tool bar. And get more for us. Thanks

http://img.domaintools.com/blog/playhouse-ear...

i am wondering to know about this tool, the name is marphed

seo ananalyzer good system I will try Thank you for your site

It's very good collection of FREE SEO Tools.

Very much helpful to SEO Webmasters.

Thanks for posting this. I used several paid SEO tools but this is much better

Great advice, even from the comments. There's some great tools and tips on this page.

Great topic, thanks for the tips and the hard work you obviously put in.

For some reason Overture's Keyword Tool was removed a while ago.
I for one miss the simplicity of typing in a keyword and getting those nice, juicy results on which to base a little bit of the SEO work I do for my affordable web design clients.

It's very good collection of FREE SEO Tools.

Very much helpful to SEO Webmasters.

With all theses great tool floating about any body can become an SEO professional in no time.

Probably the best tool of them all is Joost de Valks Yahoo site explorer plugin. Ill let you guys research that yourself.

This is a great list of free SEO tools, i'm currently going through them and there is really good stuff, i only really knew about google analytics and had know idea there are all these other great tools out there.

http://seopen.com/seopen-tools/pagerank.php is what I mostly used..when toolbar got hanged. :D Iwebtools are another brilliant stuff. Anycase I stumble them all. Thanks

Thanks great set tools ....

good stuff, i only really knew about google analytics and had know idea there are all these other great tools out there.

Seems to me most of the power is in the desktop based SEO tools since they use the processing power of your own PC instead of sharing resources with every other user who happened to be on the server. A great collection nonetheless.

Hey Brian thx for this excellent list... how about adding a list of some backlink and meta tags generating tools...

A tool that I use on all my sites is SEO Trail . I think it is worth a mention. SEO Trail is a search engine tracking tool and a social networking tracking roll-up that monitors how well a site is performing across various indexing and ranking platforms....

That's a truly awesome list of sites. Most I'd heard of but a few are new. Thanks for the info!

This post has been quite enlightening to say the least.
I think there should be a strong move by the industry to bypass the Big Daddy - namely Google Analytics.
I am impressed by Google and its philosophy of user 'centrisim '.....but, the issue is what is the guarantee that Google will maintain its outward-looking user-centric philosophy and work style. What if the current top policy makers are replaced and we get ... gosh! I am too afraid to spell out! It would be too late then, Google will already be all-prevailing and all-prevading by then.
Thoughts on this will be interesting.
Jefferson

Thanks for posting this. some that i haven't come across but are great tools..

There's a site that I use called SEOGroup.com to track my Google SERP positions. You can submit up to 3 keywords per report and once it's there, it'll be displayed in a graph. The site link is http://seogroup.com/evaluation/ ... Its definitly free to use and once it generate the report for you, there's some helpful hints as well too. Hope this help anyone out there who's looking for a free seo tool to use.

i have herd of a few of them like Google analytics & SE for Firefox but im glad i came across this post.

Yeah the SEOMOZ rank checker is excellent. I find it one of the more accurate rank checkers especially for the UK. Most of the tools I use are firefox extensions.

FlagFox for an easy check on the physical location of the physical server
NoScript for security and also I find it is excellent when visiting new sites you can see if they are using any naugthy NoScripts and it also useful to see how usable a site is without the JavaScript on.
SearchStatus for quick PageRank/Alexa/Compete info
SEOpen so I can check backlicks/pages indexed/Whois quite easily
And also WebDeveloper for multiple options

And I wonder why my computer runs slowly sometimes

Check this out: smartpagerank.com and domainpagerank.com. I know a lot more better seo tools.

Thanks for posting this. some that i haven't come across but are great tools..

These are really great tools. All webmasters should use them. I was really inneed to some of them. Thanks.

thanks for posting usefull list

Tnx a lot. This site provides and helps to know the top seo links for newbie and webmasters. This site reduce time to get top seo links from search engines.

Just to say thanks really, I love these even though I'm an amateur at all this SEO stuff !

Neither of the WeBuildPages tools are free anymore unfortunately. Has anyone yet mentioned SubmitHelper for submitting and tracking of submissions to search engines and directories? It's not a panacea but it's a good place to start submissions for a new client.

Thanks for posting this. some that i haven't come across but are great tools..

SEO is a a moving target great list of tools . Anything to make our life bit easier is a winner for me

A great list of tools - thank you for collating them. Some I've seen before, some are new, of which I'll try!

I provide SEO in Chester, Cheshire UK and have gold account with iwebtools, its well worth the couple dollars a month to use all SEO tools unlimited!
Its a great SEO website and you get 10 SEO friendly directory listings aswell.
SEO Chester.

Number 8 is my favorite tool

Another tool which might be considered very useful (although intended for AdWords, not SEO) is the Google AdWords Suggestion Tool

https://adwords.google.com/select/KeywordTool...

The reason this is useful is to check for the search volume for a particular keyword in your area. It is also absolutely fantastic for finding popular keyword synonyms and 'long tail keywords' by finding low competition / high search volume keywords. There is a fine art to this and keywords should always be cross-referenced against the SERPs to check the level of organic competition - it's usually a pretty good indicator though.

SEO is a a moving target great list of tools . Anything to make our life bit easier is a winner for me

@ rif chia - thanks or the dofollow tool. It works wonders

Thanks very much! I only new about a few of these tools, I'm sure these will help me rank much baetter than I already am. Thanks again...

I have now been using this list for a couple of months and it's hugely helped my SEO work. I feel that I have gone from an amateur to a semi-pro in a matter of not much time at all. Thanks so much for adding this to your website :)

Thanks for posting this. some that i haven't come across but are great tools..

thanks good post

You forgot of course to add ExactFactor, the bese keywords ranking tracker.ExactFactor.com
I'm using it on daily basis.
However, I like the list.

Thanks for the list, i usualy use Google webmaster tools which you have mentioned for checking how google sees my website and i also use Free Seo Tool to give me an indepth report on how i can beat my top 10 competitors.
I would never pay for seo tools as i think there are plenty of free ones available.

Thanks for sharing this great collection of tools, I usually use seolog and webuildpages tools, others are great too.

Thanks for this awesome list. Another great free tool to check out is reviewmyweb.com. It provides a free SEO review for you vs. your competitors in a single report!

You guys must have never seen rhinoseo.com. The have a whole suite of tools built around link building and SEM. If you've heard of hubspot, it is just like it... except hubspot charges $250 a month.
Seriously... I've been using Rhino Analytics for almost a month and I'm addicted.
They are also almost done with a mobile version.

Thanks, this is a really useful list that I will regularly come back to!

Good list, I love SEO for Firefox, it saves loads of time and helps me to prepare for new client meetings. One that I would add to the free list is the Google Website Optimiser. We use it for conversion rate optimisation. Another one that is great, but only free for a trial period, is Trovus Revelations. We have been using it for months and it's far more in-depth than any analytics tool I've seen.

To the last few posts (Kent, Scott, David, MidasEffect, Adsensor, gohans, and Andrea) - thanks a lot for stopping by and for taking the time to comment on the SEO tools list. We really appreciate it!

Great list. How about seobrowser.com This is pretty interesting and free.

Is there a tool that lets me see my site like google does and points out all the errors i have made?
