If I had to do parasites, I would just parasite on something like YouTube or Instagram or TikTok.
There's no need to go as far as parasite SEO on Google if you're doing just CPA.
It's like a cannon to kill a fly.
Parasite SEO can help you sell something expensive quickly like a car or a loan. Using it for just CPA is really, really a lot.
I practiced parasite SEO and it's really a lot of effort, so you need to find something that really pays big to make it worthwhile. I earned maybe $2000 in 10 days and I quit that cause it required so many posts, like 1000 a day, and every site owner saw what I was doing after hours.
If you want to keep those posts alive, just pay someone. You can even go to Forbes and ask them for an article.
Going back to question. No, you can't rank parasites with GSA SER for few reasons:
- They'll die quickly once site's owner notices traffic to some articles linking to odd sites.
- GSA SER itself isn't enough and you need powerful lists which are hard to create. It requires to create a scraping machine that is connected to it which is really like setting up a new business structure.
I would ask myself, do I really want to mould myself in something that few people can do due to complexity.
This would be a starting point https://www.blackhatworld.com/seo/tut-how-to-easily-build-huge-sites-lists-for-gsa-ser.605958/
But then again, why do this when you have free traffic on social media.
Parasite SEO pages die quicker than well done videos / pages on social media. It's easier to play around AI moderation on social media than human moderation on websites. I would analyze other places.
Reduce the complexity if you want to see money in less than 5 years. Instead of doing Google -> someone's site, just go directly to a search engine and have your own stuff there like videos / ads / images / text. People who want to do parasite SEO for small numbers are missing the point, it's not for small numbers.
