Tools That Assist with Search Engine Optimization
Google Alerts - You can use Google alerts to monitor your competition and some search terms. Eric Ward in "Link Building Secrets" revealed a killer strategy to monitor .edu and .gov domains. We shared it in an article titled "Link Building Tips From Experts." Here it is again:
Keyword String for Google Alerts: -yourkeyword site:edu
Set up one alert for a "Comprehensive" search and another one for a "WebSearch" once a day. This will make Google notify you of new .edu domains that have content related to your site, but do not have a link to your site yet. Once you spot those sites, you can discuss linking with webmasters.
SEO for Firefox - This is an extremely useful tool from SEObook.com. It puts useful SEO data right in the search results. This information includes page rank, domain age, links (from Yahoo), .edu links (from Yahoo), .gov links (from Yahoo), del.icio.us, Technorati, Alexa rank, Cached, DMOZ, RSS subscribers, dir.yahoo.com listing and easy links to Whois. This is an extension for Firefox, so you'll need the Mozilla Firefox browser.
URL-Info - This neat tool gives a ton of useful statistics about a page. Statistics includes header, link, and image information. It goes into detail and shows external links, internal links, link distribution and more.
SEO Browser - This tool shows how search engines view your site. Basically it strips away the CSS or any styling on the page, and shows plain text with links. It can give you a good feel for how search engines perceive sites and the web in general.
Copyscape - Catch plagiarism! Search for copies of your articles on the web. Copyscape is partnered with Google, so if Copyscape catches duplicates, so will Google. Free search is limited to 10 results. You can use the premium service, which costs a few cents per search. This tool is also useful at checking copy writers for plagiarism or plain copy and paste.
