Linking between 4 eccomerce

Hi ,
we have 2 ecoomerce website around 200 product each site ,
noth is in same niche , can i get backlink from eachother , like 200 backlink from one site to another website or i can get only one link

200 links from 1 site, this was a tactic like 15 years ago. It's a red flag to do now. Google can do a manual penalty or a silent shadowban kind of algorithm penalty.
1 link should be fine.

You can exchange backlinks between your own sites but not 200 links from one to another. That is a clear link scheme and Google will detect it easily since both sites are in the same niche and likely same IP or hosting. It looks completely unnatural.

The safe approach is one or two contextual links placed naturally within relevant content. Treat it like you would any third party site, relevant anchor text, editorial placement, and not overdone. Quality over quantity always applies even for your own network.

if there's no relevance between the links it could be a problem (google might see it as a trick to influence rankings), but if you manage to place the links under relevant categories (of each site) a few links won't matter. But 200 could hurt, so stick to only 1 or 2 links if you can

one or two links are fine bro but 200 cross links between same niche stores can look forced better link only where it helps user

I would avoid creating 200 links between both stores. A few relevant links make more sense Too many cross links can look unnatural Focus on useful product or category connections instead
