One name or different?

Question

Search Engine Optimization

There is an office, well, let's say the name "mobi-repair" for repairing phones / laptops / cameras and so on.
There is a site. It's promoted under "phone repair."
The task is to make a few more sites, and promote each of them. "Repair of laptops", "repair of set-top boxes", "repair of cameras".
I don't even know if it's SEO or not. It is better to position the new ones with the new names "laptop repair", "photo repair" or leave the same name "mobi repair". Domains for these sites will be new. Not on subdomains.
And the sign at the office - one.
Or which is better and why?
Thank you.

Answer 1

Make one corporate site normal. Or do you really have enough resources for quality service, promotion and advertising of 3-5 quality sites?
It will be difficult to promote landing pages, these are landing pages, and the topic is not so “non-competitive”.
Make three unique sites with unique content, convenient, useful, optimized, etc. - here it is long and expensive.
The corporate website can be moved by SEO, start a blog there to post articles / videos on repairs, describe each service in detail, with reviews. For context (etc. advertising) - each page is like a separate "landing" in the site, with points of sale, etc. Those. you can use it without any problems.
