SEO met Class C subnets achterhaald door autonomous system?

Erg bedankt voor je respons. Ik ga verduidelijking vragen en post het uiteraard hier terug.

Ik het relevante deel van de correspondentie even posten:

Ik:

Vanuit SEO perspectieven wil ik enkele sites overzetten op andere servers. Is het mogelijk om met jullie https://www.dutchwebhosting.nl/nl/web-hosting-quote.html pakketten de sites op verschillende class C subnets te laten draaien? Hoeveel subnets hebben jullie tot je beschikking?

Respons:

I think your information is not completly up-to-date. The search engines don’t rank because of Subnets, but if the pages are in different AS (autonomous systems).
Background is, that a Subnet can be a set of 1, 2, 4, 8, 16, 32, 64, 128, 256, 512,….. IP numbers (where Class-C or the /24 is the collection of 256 IPs), which are grouped to a net. But Subnets don’t tell anything about if the sites are hosted in different Datacenters or at different Providers – while the AS number as a routing tag identifies this quiet well.

To make a long story short:
– we have many Class-C networks
– spreading pages over different Class-C is these days not helping in SEO, as long as the different Class-C belong all to the same AS number. Several years ago this was different, I agree.

Respons:

About the SEO, let me quote Scott Offord, the Director of Internet Marketing at Orion Group:

“Why is the question of the dedicated IP is still so prevalent even a decade later? Not too long ago, the “trend” in SEO was for companies to create multiple mini-sites (perhaps 20-50 or more all with unique, but similarly-themed content) for the purpose of flooding search results with as many of their own web properties as possible. Each of these sites would have had their own domain name and would need to be hosted somewhere.

Because of the fear of getting penalized by the search engines, webmasters started looking for unique C-class IP hosting, where they could be allotted multiple different IP addresses that made it seem like their network of mini-sites weren’t related to each other. This was clearly deception, and among an entire category of black-hat SEO practices that Google has caught on to and de-ranked of late.

If you are practicing such shady tactics as describe above and require that many unique IP addresses, and Google hasn’t caught up to you yet, it’s only a matter of time until an update like Penguin or Panda de-ranks the scheme.”

… and the Google Penguin algorithm is by the way the AS checker for linking sites: “[…] As the update focused on the quality of backlinks, so the result varied for different websites. Google specifically mentions that doorway pages, which are only built to attract search engine traffic, are against their webmaster guidelines. Regardless, many people still use this technique. […]”
