How do you do your PBN?

I'll be glad if you help me.
I'm new here and I know these questions will sound stupid. I read lots of articles, but had no practice with registration of domains.

1. What sites are you using to find domains (not counting direct links to auctions)
2. How do you register the expired domain? Probably using some app/site or manually? (Never did it before)
3. What services do you use for controlling these domains?

Also, if you have some links/artilces, send them to me.
Thank you.

1. We are using our personal crawler, but expiredomains.net, Godaddy's auctions, Namejet, Dropcatch etc are great places to get domains. Also, check the marketplace, there are a bunch of domain sellers.
2. We register all domains manually.
3. We use our own management panel, but Excel (which we use as well) works pretty well. No need to over complicate things.

You can use expiredomains.net, domcop.com or a software called Domain Hunter Gatherer which has a free trial. You can also reach out to someone who is selling expired domains themselves. I'd recommend @Nargil if you chose to go that route. You can register domains at namecheap, godaddy or any other domain platform that you'd prefer better. Excel is probably the best fit for managing work like this.

Don't overthink it, it should be quite simple if you do things correctly!

Many thanks.

Does somebody use/used DesktopCatcher?
