Yes, but not just any IPs. You don't want to rent a VPS and throw 50 cloaked IPs into the mix. This will get you de-indexed sooner than later.
You want a truly unique hosting approach that leaves no footprints in the proverbial sand for Google to find.
I'd recommend you look into cloud hosting providers, like:
- Digital Ocean (starts at $5 / month for a small droplet)
- Vultr (starts at $5 / month for a small droplet - sometimes you can grab droplets for 2.50$ even, but they are rare)
- Linode (starts at $5 / month for a small droplet)
- Rackspace (starts at $10 / month for a small droplet)
- Cloudways (managed DO/Vultr hosting, more expensive at starts at $10 / month - but it's easier to set up and managed, which is a big plus).
- AWS
These companies offer very afforadble droplets on truly unique IPs that are not shared with any other website or even worse PBN site. They are cheap, "relatively" easy to set up and easy to scale & manage.
But the biggest advantage of cloud hosting is that you can host each PBN site on a truly unique IP that is not shared with any other sites + you can use their nameservers, which are used by thousands of other sites and apps.
For 50 domains you won't pay more than $300 / month in hosting.
Make sure to keep an eye on additional footprints, like:
- Hosted on unique and truly dedicated IPs
- Not using any custom nameservers
- Registered with a variety of reputable registrars (not all on the same date and not with dropcatch providers, they should use big ones like GoDaddy, Namecheap, Name etc.)
- Niche relevant sites with topical relevance in mind
- No thin or spun content is being used for the posts
- Customized with a unique logo
- Customized with unique about us, contact us and legal paper (privacy policy / ToS)
- Customized with a cookie banner (no GDPR compliance = big footprint)
- Using a variety of themes or at least differ in the way they look
- Not blocking bots (yep, we said it... sue us lol)
- Having proper Whois Privacy (in times of GDPR this is a privilege and not a footprint)
- Not interlinked in any way
- Using the right homepage version (root or www not both)
- Use internal links
