Can someone give a light to my question: why the same company creates different websites that offer the same service?

For example, one foreign company owns: BestEssays and SuperiorEssays. Almost all companies own more than one site and they use the same writers anyway?

What is the point? Is it to trick clients into thinking they are dealing with different company?

Like, when you got burned on one site, there are more chances this client will still order from your company?

And some owners have more than 20 websites offering exactly THE SAME SERVICE.

Isn't it better for them to try to build a brand and manage everything from one website?

Do you imagine Google to try to promote both google and searchengine at the same time?

I just don't understand it.

The only possible reason, as I mentioned above, is that they may count on the same student to order from them even if this student was scammed by that company in the past.

Your thoughts?
