Automation SEO techniques

Hi guys,

I need some advices of our SEO experts

I'm selling a digital product using SMM panel I build for youtube(I've my own method) I' m guetting enough customers to generate around 4k/month with my strategy but I have a long term vision and I want to learn SEO techniques that could rank my website and bring me organic traffic. I' m a python developer so I want to use my skill and automate task.

What I've been doing since now for SEO:

- I scrape blogs that as a lot of interaction in my niche -> I rebuild the blog(using AI and python) and make similar blog and re-post on my site 3 times a day 100% automated.

- I developped a crawler that will look for expired domains and keywords. (but i don't know yet how to use those)

My question:

-Since I can build very sophisticated bot (Handling Fingerprints, 4g mobile proxies, cookies farming and mimic human behavior like reading blog and playing videos) I was wondering if sending traffic to youtube/reddit and other trusted site as backlink to my website will improve my global SEO? --> I really need to know if these is good idea because I can bring thousand of trusted traffic.

- Where can I learn more about expired domain and linkbuilding? is it really worth it?

-What techniques should I look for my purpose since I can automate most of the task?

Thanks in advance I would appreciate any help and sorry for my English not my main language

I think automate routine SEO tasks with Python scripts and then focus on genuine outreach to earn real backlinks.
