More domains or one, which is better for SEO?

Question

Search Engine Optimization

There is such a situation:
there is a project in 7 languages, a separate domain was bought for each language, and the project has been successfully working for almost a year,
some domains have more visitors from search engines and some less
when we launched, and our competitor launched almost exactly the same project, and also in 7 languages, only he put them all on 1 domain
right now he has 32 times more visitors than our
PF, he is not better, the design is not better, the content is also not better
, only this feature with the domain remains

• Do you think it can affect traffic so much?
  
• And is it worth moving all 7 domains to 1 new one?
  

Answer 1

only this chip with the domain remains

Nifiga not only . A lot of things can affect the number of visits.
1. Are you sure that the competitor only attracts visitors through organic search results?
2. Are you sure you did the right SEO site? (Markup, texts, linking)
3. Are you sure that the behavioral factor on your site is better than that of a competitor?
...and many more "Are you sure..."!

Answer 2

Of course, 1 domain is better than 7. All links lead to 1 domain, all other factors are also not sprayed. But!!! This does not mean that everything is bad for you just because of this. This is probably just one of the factors, read Lander 's comment , he is 100% right.

Answer 3

And where did you get the idea that there was only one chip left with the domain
? External SEO still gives a great effect, often more than internal, and you listed only internal factors, if it applied at least a little to external ones, but you don’t, then it’s logical that he succeeded.
Your conclusion would be logical if in the results for all requests his site would be the first and yours the second, but I think this is not at all the case

Answer 4

Here Lander is right, there are many things you do not take into account.
1) Maybe, but there are many nuances - it can connect a couple of hidden PBN grids, and all will refer to 1 domain. And you have 7, and you are simply ruined by reference. Your situation is also in the black, but more expensive - for the future.
2) Of course not. Dig further and improve websites and external ranking factors. It so happened that you have a long-term strategy, so use its advantages. Breaking everything because you are desperate is definitely not worth it.
