hello can you tell me if what I am thinking about for SEO is correct

Are the keywords I should use for different platforms different? I mean should my product sheets be different depending on whether I sell on ebay or Amazon or something else?

I think so, I mean the products searched on amazon are not the same as those on eBay?

I thought that to write my product sheets you need an SEO tool? and even several?

I mean do you need one for each platform?

I can't take the keywords from the Google search console to write each of my product sheets?

Is it only for SEO on Google?

Was my product catalog created on Google sheet?

Can I use the API of this type of SEO software and connect it with my Google sheet so that all the right keywords for each of my product sheets go directly into the columns of my Google sheet for each product?

And so I don't have to do a lot of copying and pasting?

Would it be a good idea to use browser automation studio?

thanks
