Hello, my first issue is at the Google Webmaster tools. There is many 404 errors, which I would you to fix, maybe by a creating a friendly 404 URL or by some redirect plugin. I have 3 different redirect plugins, but unfortunately they not work (maybe there is a missing code at the [login to view URL] or htaccess files). Second, I would like you to check for global errors in my webmaster tools. My website has many content, but few visitors. I am pretty sure that something is wrong with the index or non-indexed pages. The last thing I would like you to do is to install a google search on my website, instead of the regular search that already installed. For exemple – [login to view URL] (the search engine at the top-left of his page) My website URL is – [login to view URL] Regards, Eitan
