Well dear you need to get those keywords which can can give you leads and the long tail keywords can definitely give you leads ..

 

Mate don't worry about yoast and it's stop word feature. It's just a guideline.. it wont effect onpage seo.

 

I would prefer long tail keyword since it brings my app in more search results.

 

Stop word are those words that carry little to no keyword value and can not use in domain name but we can use it in the title of any article. Long tail word means related words to the main keywords. We can use it in content.

 

CTR for 1,2 and 3 word searches is relatively lower than that of at least 4 word searches. That's because of less competition and more specific search terms
