So, SEOs are freaking out on Google personalized search, now that it is the default. Can't blame them really but now it is time for action, right?
David Harry on the Huomah blog put together a white paper as a zipped PDF file back in October 2008, which he promises to update, with some key findings on how Google personalized search impacts SEOs.
Let me quote his key findings back then, but downloading the white paper might be worth your while. David concluded: No two SERPs were the same (personalization ON or not):
- Personalization re-rankings are minimal (for informational queries)
- Establish geo-graphic baselines (or segment data even)
- Top 4 positions are primary targets
- Top 10 are secondary targets
- Top 20 may be leveraged through behavioural optimization
In the Sphinn thread discussing this, David said "we're working on another round in light of the recent announcement." He doesn't expect it to change much, but he will look into it.
