2 You do not specify a canonical URL on your site. It's common for a site to have several pages showing the same contents. If search engines know that these pages have the same content, we may index only one version for our search results. How do I specify a canonical URL?
3 You do not specify Charset on your site. The charset specifies the character encoding used by the document. We recommend using Unicode/UTF-8 where possible.
4 We did not find CSS-based print-friendly versions on your site. You can use the very same HTML but applying a different stylesheet, in which you can disable menus and other elements that make no sense on paper. Just use the media="print" attribute in your head link.
5 We did not find robots.txt on your site. A robots.txt file restricts access to your site by search engine robots that crawl the web.

Overly complex URLs, especially those containing multiple parameters, can cause a problems for crawlers by creating unnecessarily high numbers of URLs that point to identical or similar content on your site. As a result, Googlebot may consume much more bandwidth than necessary, or may be unable to completely index all the content on your site.
