Here are some of the best SEO Tools. Check back often since I add a new tool about every week. Every company on this list was selected based on merit.
(Please note: some links in this list might be affiliate links. See the full disclosure on these at the end of this directory.)
Wil Reynolds, the master of SEO recommended the following tools for use by any SEO professional:
Raven Tools - To help you find links and track keywords. Does a great job with text. Great tool for identifying keywords. Link takes you to a free 30 day trial.
Authority Labs - Provides text, video and images ranking.
SEOMoz Toolset - Open site explorer helps you value sites from one to the other when building links. MozRank and MozTrust provides a good relative comparison when determining where to place links.
Google Suggest - keyword suggestion tool
UberSuggest - simple to use, free keyword suggestion tool
SeedKeywords - tool that creates a scenario and then you can see what friends would type to search for the scenario. "Ask if you were looking for xyz product, what would you type in?"
Soovle.com - another helpful (actually way cool) suggestion keyword tool that works with Google, Bing, Amazon, wikianswers. Helps to differentiate keyword searches from Google vs. looking for a product on Amazon. Provides suggestions on 1 screen.
Amazon Keyword Tool - Most keyword tools show all keywords surrounding a term, and it's up to us to determine which of those keywords have a research intent vs. a commercial one. The Amazon keyword tool limits results to those found in a commercial environment. It doesn't offer the level of intel or value that a tool like SEMRush does, but it's a cool secondary keyword research tool for helping you identify search terms with a commercial intent. (change default country in search bar from Germany to U.S.)
