Various tools exist for websites in english.
$50 is very conservative for GSA SER.
$30 VPS
$10 Proxies
$5 Catchall VPS + domains
$10 Xevil monthly fee
$30 Content
$20-40 link list or another $10 for scraping proxies
$5-10 for indexer
-> $110 - $130 is more realistic, subject to all software licenses are already there. Plus x working hours just to keep SER running.
My first license dates back to around 2011 or 2012. I used to run it on my home PC, and I'm still using the same license with 10 threads on my home PC. (Now, I no longer live in New Jersey, and where I currently reside, there are very strict broadband regulations, yet I can still use it.)
To start running any SEO tool, you don't need a VPS. (i am not sure why you specifically mention gsa ser)
Content is either free or costs $5 with OpenAI credits. (You can easily find some sellers here as well.)
You don't need to scrape. You can easily grab a link list or extract links from a current list. By the way, from the start until now, I have purchased link lists; it's much better.
Once again, I am not a big fan of indexers. A beginner, or if they use Ranker X, can simply use a speed indexer for a few bucks. They offer 100 links for free as well.
All the tools you and I mentioned are needed for any SEO tools, not only for GSA SER. Plus, it depends on the user and the project.
PS: you dont need xevil to break the captcha just install Python and run capv2v3 with ip6 proxies. 10 threads are more than enough, and you get 50 threads.
If you purchase Xevil then you need an acceptable high-end vps for beginners i don't think it's a good idea to grab Xevil.
Actually, you dont need even $50 per month to run SEO tools.. just $30 - 20$ enough for startups.
