I am a web developer from south Germany(near Swiss/French border). I create websites for a couple of small clients. I want to get responsibility about SEO too. But I am relative in in this part. Which tools should I use to monitore SEO position and improve it? I have found just some webservices which shows just Pagerank, Alexa, Compete etc. But most of that services are just USA related and they offer nothing interesting for european/german users. Thanks!
