Google makes constant efforts to improve the search algorithm and detect quality content and that is why it rolled out the Google Panda 4.0 update. What is this update really doing? It deranks low quality content and boosts the high quality one, according to Google’s idea of valuable content.

For our client: We were lucky enough to remove most from the prior agency outreach, we also went directly to many webmasters in which we wanted to remove links.

The big other search engine people recommend is, of course, Bing. Bing and Yahoo have something of an alliance, with Yahoo taking their data primarily from the Bing index, so appealing to either one is the same as appealing to both.

Bing also has a bit more of an emphasis on links from edu and gov sites.
It might happen to have some lost links from now and then or a broken page due to some crawling issue or something similar. Yet, when your broken pages and links form up a figure just as big as your phone number, then you might be facing a problem; in terms of site user experience and organic traffic as well. Your bounce rate will increase, your overall usability, you will be loosing links and therefore you will start asking yourself “why did my organic traffic drop”?
