Still, if you've been using this data to see how you france email list fluctuate in the "normal" (non-personalized or geo-targeted) results, it's still solid for that purpose and may actually help you determine if you're gaining or losing in the new, personalized world (if you get more traffic but rankings stay the same, personalized might be helping; if you gain rankings but don't proportionally benefit in search traffic, it may be hurting). _ The Rich Get (Even) Richer Those at the top of the results, who "own" the queries around their niches are likely to benefit disproportionately as mid and long tail queries that would once have shown more alternative sources will now bring up those "previously visited" sites even if their traditional relevance and popularity scores wouldn't have earned them a top position.
This will likely contribute to some lowered diversity in the results, but may help fight against low quality re-publishers and content aggregators in favor of trusted brands. _ User Experience & Branding Boost SEO (Even More) It's always been critical to make users love your site, but now the direct SEO impact can be felt even more strongly. Sites and brands that "suck at SEO" may even find themselves performing better if their users love them and the pages are, at least, accessible to engines.
