google starting to use “Previous Query,” in serps ?

[vagrant]

Danny Sullivan discusses the new technology with direct quotes from Google’s Marissa Mayer...

For example, search for [spain] then do a new search for [travel], and you may notice how the ads will be targeted around Spanish travel (see also Google’s help page on this). Google’s never given this feature a formal name, but Marissa said internally the company calls it “Previous Query,” the first time to my knowledge that we’ve had some type of formal name put to it. Learn the name well, because Previous Query refinement is now coming to unpaid or “organic” search results, she said.

For example, if someone were to search for [spain] and then [travel] after that, BOTH the ads and the organic results will be altered to take the previous query into account. To some degree, it will be as if the second query was for [spain travel].

This is a big deal. Big deal. It means that the results for many “single word” queries, which can be hard for sites to rank for when billions of listings come back, will become queries involving two or more words - and much more specific ones.

Could this explain why I am starting to see people finding my site for keywords that appear unexpected for my site due to previous search of theirs ?

Means for us doing seo this is something helpful. They are always trying to improve... for their customers, the people who make the searches.

This is similar to the "personilized search" that Google has already been implementing. Just another complication added to something that is already extremely complicated.

If the content is good and targeted, shouldn't be that bad. Of course - we have to keep in account loopholes and exploiters, that could drop some shadows on this until it's working as it meant to be.
