This is an interesting journey. If you can keep it consistent you will get some results, eventually.
I have similar websites, some are doing good, others not so much. Performance is a consequence of the time I’ve invested in each. The best one has around 150k visitors per month. This one got a lot of manual work and good interlinking. General niche, translated content, lots of content
Without links, growth will be slow. The most important asset under the circumstances is patience and consistency. If you have access to links, that’s great, otherwise there is a possibiliy to get natural links from all over, with one condition: content should be fresh, structure and grammar great. Otherwise no links. Usually, websites TO English have a higher chance to get links.
One of my German sites gets around 500 visitors per day, tech niche, and managed to acquire during the last 6 months a few strong links by itself. Just a few.
Texhnically important ( proven criteria):
- No downtime, ever
- GSC spotless, no errors whatsoever
- Combine info content with commercial intent content
- interlink only when it matches the topic
- categorization
- tags only when you plan to add several articles within the tag
- pagination for front page, categories and tags should hold as many articles as possible, without damaging loading speed
- caching (great combo there, solved)
- Indexing API will get the bot visit your site but does not guarantee indexation
I’m still perfecting stuff, and try to keep myself organized. Hundreds of details.
I hope this helped a bit.
Good luck with your journey!
