12 Stellar SEO Tools
Analyze your site to get the best results
When you’re ready to get a good look at how your site is stacked up for SEO success, there is no shortage of SEO tools that you can use to analyze your site inside and out. The tools listed below are some of the best of the plethora of great SEO analysis tools available today.
See your site like search engines do
One of the most basic and necessary SEO tools is one that allows you to see your pages the way a search engine would, because search engines may not always “see” your site the same way we do when we visit it with a web or mobile browser. Two tools are listed below—the first one is a simple check of your site in search results, and the second is a tool that you can add on to your Firefox browser.
Search Engine Cached Pages
Cost: Free
Most search engines provide a “Cached” link with their search results, which allows you to see what the search engine indexed on its last visit to the page. Our blog post “Is Your Site Invisible?” provides details on how to determine if the search engines are seeing your site, and what exactly they are seeing.
Firefox User Agent Switcher
Cost: Free
The User Agent switcherallows you to switch your user agent to make it look like you’re a search engine visiting the site, rather than a person using a web browser. The User Agent Switcher will only work if you use the Firefox web browser.

When you’re done viewing the site as a search engine, remember to change your user agent back to Default User Agent.
Keyword research and management tools
Doing keyword research allows you to get an idea of the competitive space, guide your site structure, and gives you the information you need to laser-target each individual page on your site for the most relevant and popularly used terms for each page.
Keyword Discovery

The tool returns estimated search popularity from Wordtracker and the top three search engines (Google, Yahoo and MSN/Bing) for that term and popular searches with that term or phrase in it. It also returns Yahoo! Search Suggest results, and more.

Another long-time popular free keyword research tool, the Google Keyword Tool lets you enter a keyword and determine the search popularity in Google (only) for that term and related terms. Results show estimated search volume globally and locally, plus advertiser competition on each term.

Site Analysis Tools
At the heart of any SEO audit is the on-site analysis. The following tools unearth the kinks and bottlenecks that your site might be encountering, by crawling your site, reporting errors, providing analysis, and often suggesting action items, as well.
