Hi there, hope everyone is having a good Monday! I am fairly new to SEO and am learning by doing - but I did want to make sure I wasn't making any rookie mistakes. Thanks in advance for any insights :)

I am creating a bunch of pages aimed at targeting long-tail SEO keywords. We have 2,000 keywords. For each keyword, there are 15 categories of information for which we have 2-3 sentences of custom, useful content. So, we could theoretically create 30,000 individual SEO pages.

Imagine something like this:

"Is <keyword #1> compatible with <category #1>?"

"Is <keyword #2> compatible with <category #1>?"

"Is <keyword #1> compatible with <category #2>?

"Is <keyword #2> compatible with <category #2>?

And so forth...

The 2,000 keywords are the same, but the categories are all different. And the custom content that we have is unique for each keyword-category pair. The content, though short, is actually helpful and genuinely should answer the user's specific search query.

A few questions:

1.) One of our primary goals with these pages is to prompt users to download our company's app. To do this, we can either have text links prompting a user to download our mobile app (likely an app.link URL), or we can show traditional Apple App Store and Google Play Store download buttons. Are there considerations for which might be better from an SEO perspective? For whatever reason, text links just feel less spammy than App Store and Play Store download icons? But does Google likely care?

2.) Because the 2,000 keywords are the same, we're afraid that the pages will start to look similar to Google. Each page will have custom content that varies by category, but again, that content is really short (2-3 sentences tops). Instead of creating 30,000 unique keyword-category combination pages, would we actually be better off from an SEO perspective to create 15 master category pages, each of which has 2,000 keywords on it? My only fear here is that we'll lose the connection to the very specific user query (i.e., keyword + category)

3.) If we do create 30,000 of these pages, would it be smart to remove the ones that get essentially no traffic? Would that likely lead to Google amplifying our placement of the remaining pages?

4.) Any other considerations I haven't brought up that I should be thinking about?

Thank you so much!!
