SEOs and webmasters reveal their most-wanted list for Google.

Google's Matt Cutts has just released information on a survey of nearly 2,200 votes by webmasters and SEO practitioners on their most-wanted enhancements to Google's Webmaster Console — a  tool that provides behind-the-scenes glimpses of how Google sees individual websites and provides information on a few key search-performance metrics.

Overwhelmingly, webmasters voted for more information on Google penalities and scoring issues, reflecting continuing concern over how and why the search giant downgrades or downplays certain pages within a given website. The SEO chat boards and webmaster discussion forums are routinely filled with pleas for help, puzzled postings and head-scratching musings on why Google might be taking a dim view of particular pages or of entire sites: Google often banishes entire websites from its SERPs (Search Engine Result Pages) and, more routinely, relegates seemingly harmless pages to its Supplemental Results… a kind of search backwater where pages are either withheld entirely from the listings or shown grudgingly at the very end of the main results. (Typical reasons include perceived duplicate content or other apparent violations of Google's Webmaster Guidelines.)

Indeed, the uncertainty of what precisely constitutes duplicate content in Google's eyes is reflected in the second-highest vote, which asks Google for more tools for detecting and reporting duplicate content. 

The survey results are reproduced in full below. If you have concerns about why your site, or particular pages within it, are not getting all the Google love they deserve, why not ask your SEO adviser to take a look?
