Google Webmaster Tools also allows to know if your site is infected with malware. Google Webmaster Tools is a really valuable instrument for SEO. It gives you at a glance data about all important SEO aspects of a site, such as keywords, links, crawl errors, etc. It allows webmasters to check indexing status and optimize visibility of their websites.
