SEO Tools
SEOMOZ PRO TOOLS
SEOmoz offers both free and paid-for tools. While the free tools definitely have their uses, the pro membership is definitely the way to go if you want the whole package. The tools and knowledge bases that come with their pro membership that end up paying for themselves - quickly. The subscription for the tools is a bit pricey, but for the quality and functionality of the tools and information you'll have access to, it's definitely within the consumer price range. It's actually quite amazing since clients like Microsoft, Yelp, Disney, eBay and Marriott dominate the search engines by using the tools from SEOmoz. Take Advantage of the tools SEOmoz provides to become a SEO expert!

SEO Book offers some of the best and most useful tools to be found anywhere... and most of the tools are absolutely free. In addition to the free tools, SEO Book premium members have access to a variety of exclusive premium tools that aren't shared with the general public.

WEBSITE GRADER
These tools will not only tell you how well your website is doing, they will tell you specifically what you need to work on to achieve higher success with your website. Is it getting traffic? Does it have problems? How popular is it in social media?
Find out the answers for free. Just enter your website URL and click Generate Report. The Website Grader tools will do the rest: Visit the Website Grader.
GOOGLE'S SEARCH-BASED KEYWORD TOOL
Before I learned about Market Samurai (click here), I thought this was one of the best search-based keyword research tools. It not only shows you how popular your keywords are, it also shows you how much competition (to a degree) there is for that keyword. For free tools, it's still considered an excellent choice.
