Webmasters and SEOs are back on their work of analyzing how Penguin 2 update, which is now live has impacted their websites.
Google on the other hand is also assessing things on the basis of how the updated has impacted search results, quality of search, and searcher's satisfaction. The search giant is also looking out for more ways to analyze the situation.
The head of search spam, Matt Cutts is asking searchers to report any spammy website that is still coming in the search results, after the update. Matt has also posted an online document for reporting about such websites. Searchers can mention the URL of the spam site, the query for which you got the result and additional comments (in case you have any) in the document.
