Hi Guys, Any idea about the recent algo update in Google. Do anyone have idea about the algo. How it works? Precautions to be taken?
You could ask Google: http://insidesearch.blogspot.co.uk/2012/06/search-quality-highlights-39-changes.html
I think the main way to avoid being hit is high quality content and relevance in the backlinks. Try to keep your back linking as natural as possible by diversifying your anchor texts and also using generic keywords such as "click here" or "read more" and not forgetting to use naked urls.
what kind of ideas you are looking for? recent google penguin update was a major update which targeted sites that used spam techniques to rank their sites. google also went after sites that used link farms, paid links, black hat and any other form of spamming that google can detect. precautions? well, since the update is already done, precaution is not something you will be looking for. maybe a preventive measure for the future update?
Just follow one precaution and that is to never scam. Always follow valid and valuable activities on your website. Google won't hurt you.
Google never disclose their algorithm, and no other search engine also. But what we can guess is, this is something anti spamming and dislike bad quality link and blackhat SEO.
