What is the best way to promote an online store?

Question

Search Engine Optimization

There are three areas in which I work: pumps, Spare parts for petrol tools and auto tools. There will be about 1000-2000 goods in each direction. Such a question, how best to implement for promotion? To have three separate sites, to have one, but different subdomains, or to have all the products on one? Thanks in advance.

Answer 1

In general, for SEO, it doesn’t matter if you don’t fill up the main page with links and traffic

Answer 2

In general, in general, a site with a more developed structure (the number of products and categories with proper optimization) will certainly benefit from 3 different subdomains, you can also expand the semantics using a filter and search slices.

Answer 3

As only the search results will tell you better.
See how your direct competitors and competitors in the search results have done and repeat.
But the larger the IM, the better.

Answer 4

You have to stick to the budget.
In any case, it is clear that the main page ranks better than the internal ones (ceteris paribus).
Therefore, 3 separate sites for specific topics are better than one general (provided that the sites are zero).
But the budget will be more than for the promotion of one site.
