Xenyo has created and hosts some of the best SEO Tools available for webmasters to manage their sites and analyse and improve their SERPs.
Webmaster Tool - This free online tool allows webmasters to manage their links to and from their sites, control their link building and keywords RoI and help do their accounts at the same time.
Page Rank Verification - This online tool will check URLs to Google's cache to make sure that the URL shown on its Google Toolbar Page rank matches the one stored in Google. Additionally, it shows the number of indexed pages and backlinks the URL has to further verify the page rank.
Page Rank links Chart - This chart indicates roughly how many links it takes an average site to reach a certain page rank. The data is taken from live data so the numbers shown for low page ranks should be taken lightly.
