Over at the Official Google Blog, Google’s Steven Baker just announced a major change in the way that Google handles search results by including synonyms for some words that may be used in queries, in the post Helping computers understand language.

The deal between the two search giants is now official.  Microsoft will now power Yahoo! search while Yahoo! will become the exclusive worldwide relationship sales force for both companies’ premium search advertisers.

What’s in it for us though? As SEO practitioners, maybe minus 1 search engine to consider. Optimization would now be for 2 big search engines, Google and MicroHoo (whatever they may call it).

For PPC managers though, it poses some questions. Would be AdCenter or Marketing Solutions? What will happen to the PPC campaigns on both Yahoo and Microsoft? Will there be an increase or decrease in CPC, impressions, CTR? What will be the rules? Will there be new ones?

Everything seems to be a wait and see.

Google unveiled another feature to the search fanatics. Google Search Wiki. With this new feature, you can personalize your search results, move or even remove a particular result, thus making it more relevant to what your looking for.

Though not yet affecting the search ranking as a whole, there’s a big possibility that in the near future, ranking in the SERPs would be affected by this feature.

Would it be good or bad? Only time will tell.
