[Safa]

Does anyone know of a good and free tool to check the SERP ranking of a website for certain keywords?

Im lost so far I used this, Google SERP PageRank Checker report: Top Rankings Position Check many countries Google search engine results position (SERP tool) SEO web tool but is not working any longer and when it works it stopes again after a few weeks, seems the webmaster of the site don't really care about it.

Would appreciate any link or help.
