I made a plugin for WordPress that shows how your host is indexed in Google and is it “trusted” or not. How it works: first, it is querying Google for site:your-blog.com, then it extracts first 10 titles from response and qurying Google for this titles. Then it is searching for your blog positions in the responses and showing it along with the query as a number, so you get 10 numbers as you can see it in my blog. The smaller number is the better Google “trusts” to your host. When plugin is installed, you can see numbers at your dashboard and also add a widget to show it to your visitors. Data are updated automatically every 5 days. You can download this plugin here. Please let me know if you find any bugs or you have a suggestions.
