Thanks for your feedback Robert! I don't know how it feels to be bookmarked, but I guess it must be like feeling browser buttons coming down all over me ;-)
Great job. Also check here for the ultimate list ofweb anlytics solutions: http://www.webanalyticsbook.com/webanalytics-vendor/
Good List! I made one with categories - it is in german but many words and tools are in english... http://www.fi-ausbilden.de/seo-tools.html
Nice collection of tools Ramiro. I have used/using most of them already. your collection will help webmasters very much. However, you seem to missed another category of tools i.e. Fake pagerank Checker, that helps Webmasters while buying Domains/Links.. Two tools I frequently use for this purpose are http://www.rankalert.net/fake-pagerank.php and http://www.seologs.com/pr-check/pagerank.html Hope it adds value to your post. Cheers
Thanks Chinmay for your proposal. I'll check out these tools for inclusion in the list.
Fine list, Ramiro. My SEO Tool for WordPress: wpSEO (german & english).

I just skimmed through the feature list of your tool, looks very interesting and is well worth trying out for every wordpress user who cares about SEO.

A good and very complete list, but which ones do you use ?

Evil question ;) First, as also mentioned in the article, I have tested them all, before posting theme here. I have the SearchStatus Firefox extension installed which offers many nice features and I more or less regularly use the following tools/services listed in no particular order:

  • Yahoo! Site Explorer
  • Google Sitemaps
  • Google Trends
  • SEO Book Keyword Suggestion Tool
  • Google AdWords: Keyword Tool
  • Overture: Keyword Selector Tool
  • iWebtool: Google PageRank Prediction
  • Webalizer
  • AWStats
  • Stuckdomains: Free Expired Domains Search
  • Text Link Ads: Ad Link Value Calculator

Since I wrote this article I found some other interesting tools, so I guess I will update this post sometime in the future.

What a great and useful list. I'm sure I'll write about that list on my own blog (german). Thanks!
Hi. This is a very long list of usefull tools. Many thanks.
I´ll like to send you another tool: www.webkataloge-assistent.de is a directory entry reminder tool in german language and with many german directories.
Greetings,
Heiko

Only few Web directories will drive some traffic or influence your ranking, so for me this does not seem to be a particularly useful service, but maybe I'll give it a try sometime.

Good list, i know most of the tools, but a few are really new for me, thx
Not a good list, a grea list of good tools everyone is working with ever day, good work.
Thank you very much for these useful links.

A good tool to check the backlinks and get an idea, what your pagerank could be is the X4d Backlinkchecker ;-)

Consider adding this new SEO tool too. http://www.ezbusinessneeds.com/dofollow.php
Hi. Thank you for this list of tools. I will definitely be trying them out. Do you also have a list of all tools that we can buy. I am looking for a tool to find a list of all keywords that are displayed on the first page of Google.com and Google.co.za for a particular clients domain without having to insert all the keywords. Thank you in advance Have an exSEOllent 2008
Thank you! I shall check out these tools for inclusion in my list.
Wow, some awesome ones here, actually almost ALL of the ones I use on a regular basis.

A couple more really effective ones to add to the pot.

Keyword Research - Pre Wordtracker/Keyword Discovery

* Keyword Research Tool - Covertsem.com
(For taking your market words too, and getting back the right power searches to take to the keyword stats research tools. Great prep tool)

Competition Analysis Tools

* Statbrain
(great tool for telling guessed stats of competitors websites)

Domain Name Selection Tools

* Keyword Counter/Domain Name Generator
(This one I figured out how to make it a great tool, take your keyword list from Wordtracker or Keyword Discovery and paste it in here. Take the top 10 results, and generate a domain name or names, and your top 70-80% of your keywords will be in your domain name, truly AWESOME)

Thats it. I'll keep looking back here for more.

Rid...
Excellent list, plus the contributors added some nice extras. Will be playing with these new toys. Thank you very much for the information! Keep up the good work!

Link Builder
Thanks for listing all of these wonderful tools. In appreciation I have given you a thumbs up at StumbleUpon. Take care and keep up the good fight.
Great list - thanks.

Another tool that I use often for working on my search engine rankings is http://www.rankangel.com

This site helps you get a sense of how your page/site ranks in different search engines in response to specific keywords - and it allows you to setup projects that will retest every day and graph your results. The ability to create projects that retest your rankings regularly is great for building up a performance profile.

Here is my Free SEO Tools website.

Please add it to your wonderful SEO tools list.

Thanks, Yuriy
Great list - I've got two to add.

First Live HTTP Headers for Firefox:
https://addons.mozilla.org/en-US/firefox/addon/3829

Next The Sempai - I love their keyword generator, but there are a few other useful ones:

Hi, Thanks for that immense piece of information.Will browse through this list in depth.Sure its really gonna be useful. Great info! Regards Sarah
DO NOT change the title of pages which are already doing well in SERPs. The moment you change the title, your page will surely go down in SERPs and will may or may not come again (in few weeks time) depending the extent of change you have done to it. 2. Meta Tags spamming. Don’t waste time in meta keyword stuffing. Its useless. Just keep very few keyword in it, if you want to.
