Gambling Niche Domain for 2 brands

Hi, I have a question about my domain (for example: banana.com).

I created a gambling landing page at banana.com/menu/ (Brand A), and it was ranking on page 1 of Google for Brand A keywords.

Last week, I created a new page at banana.com/about-us/ (Brand B), and it also reached page 1 for Brand B keywords. I also built backlinks for Brand B pointing to banana.com/about-us/ using Brand B anchor text.

A few days later, the ranking of banana.com/menu/ dropped from position #2 to #8 on page 1.

After that, I removed the about-us page, then restored it again, and requested reindexing.

My questions:

• Did banana.com/menu/ drop because I built backlinks for Brand B?
• Or is it because I am using two different brands on the same domain?

I also have a similar case on two other domains. On those domains, I have not built any backlinks for Brand B yet. However, after adding Brand B pages, both domains also dropped to the bottom of page 1 for their Brand A searches.

For the future, should I focus on buying high-traffic guest post backlinks for Brand A? Or is it better to redirect Brand B to another domain? Or do you have any suggestions?

Thank you.

This is because the brand entity is split into two, which is certainly not recommended. This makes it vulnerable to content gambling, unlike the content whose intent is informative, not brand intent.

Two competing brand signals on one domain will confuse Google about topical relevance, that's almost certainly your drop. Separate domains for each brand is the cleanest solution, trying to rank two distinct gambling brands from one domain is fighting against yourself.

mixing 2 brands on one domain confuses google. u split signals and topical trust drops.
better keep each brand on its own domain.

This usually isn’t just about backlinks; it’s more about mixing two different brands on one domain.

When you added Brand B pages, you basically changed the overall focus of the site. That can confuse Google and weaken the relevance of your Brand A page, which is why /menu/ dropped. The same thing is happening on your other domains (without backlinks) confirms it.

It’s not mainly the Brand B backlinks
It’s mostly topical dilution

What to do:

Best: keep one brand per domain

Or keep everything very closely related

Build stronger, relevant links again to the Brand A page

Simple answer: your ranking dropped because the domain focus got split, not just because of backlinks.
