Personalized search has now gone mainstream, thanks to Google. What’s a marketer to do about it? I can sum up the best strategy in one word: nothing.

Google has experimented with personalized search results in beta, and during that trial, you could turn the personalized search results on or off. Now, if you’re searching while logged into your Google account, you get the personalized search results automatically, as mentioned on the Google Blog. You’ll see the message “Personalized search results 1-10 of about [the number of results]” in the light blue bar above the natural and paid results when it’s on.

It’s easy to overreact to the change. What should you make of articles such as those on SearchEngineLand by Nick Wilson, who spent over 1,000 words in his “3 Ranking Survival Tips for Google’s New Personalized Results”?  He advises optimizing for Google services, social search, and social networks and blogs.

These are all great suggestions, and they’re all helpful in their own ways. They can also be used to no benefit of the marketer. For instance, one could offer buttons, tags, and widgets that make it easier for Google users to add marketers’ content to users’ personalized home pages to the detriment of the overall customer experience on the marketer’s site. Marketers could post content to digg, the social news site, only to be seriously rebuffed by the site’s cabal; if the marketer is successful, it could drive a swarm of traffic that has no interest in anything beyond the marketer’s one buzz-worthy link of the day. A marketer can also engage in blogs and social networking yet do so in silos, thus offering no lasting benefits.

The other option for optimizing for personalized search is simply optimizing for the best possible rankings in Google’s non-personalized listings. There are three advantages to this strategy:

1) Most Google users won’t be logged in while searching. Google’s empire is growing, with logging in required for its personalized homepage, Gmail, Docs & Spreadsheets, Checkout, and other services in its smorgasbord, but the homepage at Google.com is the primary starting point, and no registration’s required for that. (Google was not able to offer any numbers on the volume of searches conducted from users logged in with a Google account.)

2) For searchers who are logged in and are amassing a search history for personalization, most searches won’t be significantly affected. Certain sites might rise a couple of notches for certain users’ queries, and sometimes there might be a major shift, with a result that ranked eighteenth now ranking second, but the changes will not usually be that pronounced.

3) It’s easier. Consider a query in Google that could have any of 25 different links that could wind up on the first page (set at the default 10 results displayed) of a user’s personalized results listings. That could lead to roughly 11.9 trillion permutations, or about 1,750 permutations for every person alive.

Nick Wilson, in his recommendations for grappling with personalized search, offered some great advice: consider engaging in strategies such as blogging and blogger relations, social media marketing, and others along with your on-site and off-site optimization programs, he said. Yet that’s true regardless of whether Google and the other search engines build in personalization. These strategies are some of the new search engine optimization best practices.

So, should you optimize for one, or for 11.9 trillion? It’s your call.
