Google has just bought JotSpot, a wiki hosting service similar to BlogSpot/Blogger.com. According to an email JotSpot sent to its members, Google will be providing free wikis/websites to anyone who desires one.
There are several implications of the Jotspot buyout for Google's business and the effects on SEO will also be significant. To begin with, in the same way that Google's standard blogger templates are search engine optimized, it can be expected that its JotSpot templates will be optimized. This means that it will be possible to deduce wiki SEO best practices from careful analysis of these templates.
Second, Google's purchase of JotSpot has an impact on keyword research and keyword selection. As many savvy SEOs know, a little controversy can generate a lot of backlinks and interest. By monitoring which pages on a wiki are most prone to editing, to flagging as controversial etc., SEOs can get an idea what topics can likely serve as link bait.
Third, just as it did when it purchased Blogspot, Google will certainly make Adsense integration easy for its JotSpot customers. This means that it will be possible to buy a greater volume of ads via Adsense's content network. The greater supply should also help to control costs to a certain extent. Indeed, some SEOs are turning to MSN's adcenter for the comparatively cheap rates; this move should help stop that drain. (The interest of search engine marketing/advertising to search engine optimization consultants is that SEM helps determine which keywords convert best, saving time and energy in the keyword selection process.)
