Already greater than 11 years in the past, I tackled the topic right here within the weblog: giant, dependable web sites hire an entire subdomain or listing of their area to a 3rd get together. Usually with out data or approval of the positioning search engine optimization crew.
This third get together makes use of Google's general belief in all the area and runs its personal web page of questionable key phrases which have a better rating on Google than on an unknown area.
In latest days, the topic appears to have been again on the agenda in Google. In consequence, a few of these collaborations have been considerably worse than earlier than. Stern.de is an effective factor to see. There are at the moment two highly effective subdirectories providing third-party presents:
Each directories (stern.de/vergleich and stern.de/gutscheine) of the identical day clearly misplaced visibility in Google's outcomes. An analogous growth will be seen in different areas and in different nations. Here’s a desk with the numbers of 25 domains or subdomains of domains left to 3rd events:
Profitable websites on international domains
Along with the key losers, there are additionally many examples of any such lodging, the place visibility has remained secure and even gained visibility within the final month.
An evaluation of the visibility of 150 instances reveals that the visibility of those instances has decreased by virtually 20% in all areas over the last month.
Danny Sullivan commented on the official Twitter account for the webmaster's communication on the topic:
Considerably, public consideration on the topic is at the moment being pushed by an nameless twitterAnd depend Medium.com. The creator doesn’t agree along with his actual identify, however has a devoted opinion on the great and the unhealthy. The sustainability with which he approaches the topic means that he doesn’t do it as a interest, however that he’s motivated by financial concerns.
And day by day, the groundhog greets. An rising variety of search engine optimizations are gaining new consideration. Looking back, the danger for web site operators, particular person sub-domains or rental directories was slightly low. Google is just within the rating of the rented content material and never the content material of all the area. A assure that it nonetheless works, however there’s none.
