There are quite a few tools available for checking SEO promotion effectiveness. But three tools are the most important — we’ll cover them below.

ValidRank

It’s well known how important link popularity is in SEO. ValidRank provides data on the number of sites linking to a given resource. But ValidRank’s capabilities don’t stop there. For example, you can also see the PageRank of the pages hosting links to a web page.

WhosTalkin

Another important SEO tool. It lets you find out who’s “talking” about your site. For this, WhosTalkin carefully scans various social networks — Facebook, hi5, Friendster, MySpace, etc. WhosTalkin checks info from Blogdigger, FriendFeed, WordPress, Twitter, and Google Blog Search.

SeoQuake

SeoQuake — one of the most essential SEO tools. It helps assess how effectively and competitively a site’s SEO optimisation was done. The tool can be used to analyse internet marketing projects and campaigns. Or to determine PageRank, outbound links, DMOZ nomenclature. SeoQuake can also check whether specific pages are bookmarked and whether they appear in Whois listings.

SeoQuake can also be used to identify secondary key phrases matching the page’s content. The tool shows how often key phrases are used and their location on the page.

An important advantage of these SEO tools is that they help simplify internet-marketing strategy development. Most importantly, they show what’s working in the SEO optimisation project and what needs improvement.
