Welcome to the Q&A Forum

Such tactics should be avoided since the traffic they (supposedly) generate is artificial and the major Search Engines have focused a plethora of their later updates towards the recognition of spam and for the promotion of quality.

The search engines can track the user behavior within a web document and in my understanding of their patents and updates, they could capture artificial behaviors.

My suggestion would be to stop the use of such services. Regarding possible penalties of the search engines towards the website, noone could quanitify their effect for sure. It could hurt you possibly but if you focus on proper structure and quality of the website, you will end up improving your rankings in the search engines.

You could also recognize possible backlinks from this service by using tools such as opensiteexplorer. Then, you coul employ the disavow tool of Google to inform it about the specific links, in order to state that you would not like this links to be taken into consideration for your website's profile.

I know that differences exist but they should not be very large scale if you use incognito mode, non-personalized.

Thanks for your answer.

Google trys to connect every term and combination of terms within a query to a search query entity. It relates the terms and the entities with a probabilistic model in order to define how closely connected they are.

Regarding now the webpage of centerofpolitics it is not in the first 200 results of Google.com (US).

Probably, due to the 10 occurences of the word larry in the html of the webpage (some on title, some in body, some in links) Google has a loose connection with the word "Larry" of the "Larry Page" search query.

Since, "Larry Page" as an entity is an authority for Google, the webpage of centerofpolitics should be a result ranked low in a search query that matches exactly the name of the entity such as "Larry Page" or "Page Larry".

I would like to perform a competitor rank analysis in Google.gr . I have noticed that the results from the rank tracker for Google.gr are different than the results in Google.gr from a machine located in Greece with no Google account logged in.

Could you inform me why such a behavior occurs?
