Thanks!
But even these are very interesting, none had the said subdomain spam.
They are pushing huge amount of content, but just on the main domains. Some things I noticed:
- Many use just random strings as URLs
- They are cloaking their offer (meaning if you try to access the pages you'll get redirected directly to campaign, not to the actual website)
- Cloaking makes it hard to check what they have on these posts, but to me this seems just sheer volume of posts and probably indexing hack. Their content is probably decent in Google's eyes so the problem is just to get it indexed.
- Footer they have ping link to their sitemap file via Google ping: <a href="
https://www.google.com/ping?sitemap=https://mertelas.info/sitemap.xml">Ping</a> - probably helping to get all these indexed. Most likely they are doing some other stuff too to get indexed
- Domains have been registered less than 2 weeks ago
My guess with quick analysis is that there's no actual trick going on, but the method is rather "simple":
- Get ton of keywords
- Publish ton of decent quality content (well the trick is how to do this fast and with low cost)
- Get this content indexed
- Find offer which converts on this kind of traffic (and accepts this kind of method)
- Profit
It sounds simple, but in reality creating 145k posts (well that's just what's being indexed) isn't easy or cheap. Just finding keywords isn't exactly that simple and then creating content for all these would cost you $14500 if just 0.1 USD per article. Especially if you are not sure what you are doing, it could go wrong way since these most likely won't rank very long.
Anyway kudos for those who still have found a way to break Google's algorithms and rank&bank in 2024.
If anyone have the domain with subdomain spam which OP mentioned I'd like to take a look.
