New privacy policy on Google SEO

In March 1º Google will implement the new policy. This consists in the integration of all google products that will be more accurate, more personalized and much more user oriented.
This step was made for the interest of user, and try to find what is more relevant for then (rumors saying that they will actualy tell you if you'r late for work based on you location and your calendar...).
Since all the Google products will be seen as one, your searches in Google will reflect the searches on youtube. So if you search for [jaguar] on Google the results are basicaly the same as if you search [jaguar] on you tube. All this happend if you'r logged on your Google account.
Does this affect SEO? Well, for my point of view...yes.
First, we must not be logged on for our results be more precise and don't "mining" the SERP's.
Second, user's don't tend to refine refine searches very much, they usualy stick to what firts pages gets, so more useful pages (and with a good optimization) may be left behind.
Third, when you search for some restaurante you can get information from a friend ( Goolge +) first and not the actual restaurante.
Most of the personalized content are here since 2005, now they introduce (Google +) on it and make you one giant client for them to study.
One other aspect is the "remarketing" of ADS. Goole can advertise you even when you'r in a non-Google website and not log on. This isn't based on what you search for but with a anonymous cookie tagged on an advertising site.
So, what does it mean?. If i search [buy car] in Google, you can start to see more Ads related to your search even if you'r not on a Google site but sites that carry Google Ads.
Finding the "opt-out" for this is no easy task but you can find it here.

There's a disable button too for Google + for them not to take relevance on your searches here.

Although remarketing has nothing to do with privacy policy. Even if you never create a google account retargeting happends through anonymous cookies.
So, if you don't bother with none of that, you will see more and more friends on search results...or simply.."unfriend" them.

The "Don´t Be Evil" Tool

Soon Goole will release the "Search Plus your World" "thing" in any language (for now only in .com), that consist in integrating social in your search results. For ex. if you search for "movies" it will give more relevant results for users (showing or hiding personal results if you want...).

But what it really does is giving more relevance to Google + profiles and NOT the most relevant for that particulary search.
This Tool (yes it's safe and very easy to install ) will give you more relevant and updated content search focusing on user. What it means is if you have a Twitter account that have more updates than a Google + profile, is that account that will prevail). The companies behind the tool (Facebook, Twitter, MySpace)want to show that it really can be possible a better and more accurate content.
Goole must do what we expect it to do, relevant, accurate, and updated content not injecting Google + pages as the most relevant.
Google + can be a great product, but Google must give him a "fair trial"
