3. Google Webmaster Tools Google Webmaster Tools, another essential and free toolset, helps you diagnose website crawl errors and perform other tasks to improve your site's "health." Though it's not particularly difficult to use, those without much website management experience may be a bit confused.
4. Google YouTube Keyword Tool YouTube videos can rank highly in Google searches when they're optimized with the appropriate keywords. Munoz recommends using this tool to find keywords that will help your YouTube videos rank in Google searches as well as in YouTube searches.
5. Google Suggest Whenever you begin typing a keyword phrase in a Google search box, Google suggests related phrases based on your own search history as well as terms popular with other users. A quick way to get keyword ideas, then, is to simply start typing a phrase in Google to see what the search engine suggests, Munoz says.
Third-Party SEO Tools
6. Screaming Frog SEO Spider Screaming Frog's SEO Spider is a desktop program that sends a "spider" (or crawler) to a site and compiles a spreadsheet-like report on the pages it crawls. You'll see title tags, URLs, meta descriptions, meta keywords and H1 tags, as well as pages that might have 404 errors. Whalen uses the program whenever starting a new site review. "It helps me get an overall feel for the site and quickly shows me any major technical issues," she says. The basic program is free; the licensed version adds more features for £99 (about $150 U.S.) per year.
8. Browseo Browseo (a mashup of the words "browse" and "SEO") helps you quickly determine a page's structure, as well as its relevance for specific keyword phrases. It's a fast way to get a helpful breakdown of a particular web page, Munoz says.
