At the end of April, Google announced a big change to how your ads will appear in the search results. The change, which took effect at the beginning of May, has to do with the ad rotation settings. The way it used to work is that you would select the “rotate evenly” option in the Advanced Settings category when testing 2 or more ads, and want them to display evenly over time rather than allowing Google to control which ads are displayed.
In what is starting to look like the next wave of Google’s assault on common low-quality linkbuilding tactics, a WebmasterWorld thread has SEOs reporting that about half of link web directories have been completely removed from Google’s index. This means that any links built on those directories have completely lost all value.
One of the most difficult, involved, debated and important parts of SEO is linkbuilding — accumulating those backlinks to a website that build it’s authority in the eyes of search engines. Because it’s so important, it’s also become one of the most manipulated aspects of SEO, leading to a constant battle between search engines and SEOs.
