I checked for some days the first positions of Google for the keywords related to the contents of my pages. It's clear that Google has been spammed for people posting in forums hundreds of keywords-links and gaining positions in the first page. Another common practice is to include page results of search engines (Fireball) with the most popular users searches in not dynamic pages. These pages are full with the keywords provided for the sites listed in those pages. Also I saw some sites including lots of hiding keywords and links within homepages very well positioned in Google.
I know that some of these tricks are really old, but I thought Google could keep us away of this.
Somebody has been seeing the same?
Could you see the same for other languages?
Is Google loosing some strength filtering spam results?
