www.SERoundtable.com – This week at the Search Engine Roundtable I cover a nice amount of topics, I wanted to highlight the most important items. First, Yahoo Site Explorer has dropped out a ton of the links, Yahoo is saying it is Microsoft’s fault. Google did a PageRank update for some. Google is testing a new AdWords Preview Tool, check it out. Advertisers are seeing huge spikes in cost per click costs since the Yahoo and adCenter migration. Google may have stopped indexing Blogspot domains. Google might not wipe out your old links after a reconsideration request, but you should submit one when you buy a new domain and there is no way to cancel it. We have some more May Day theories for you. Google talked a bit about HTML5 and how they index it, on an SEO basis. Google brought back the report offensive images in Google Image Search. Google is testing a new auto detect location feature. Google Maps now divides reviews from third part sources. We covered SES Chicago this week. Google had a logo for Dizzy Gillespie, famous Jazz trumpeter and they now have logos for your very own birthday. That was this week at the Search Engine Roundtable.
