It is so bad that in the official play store app ads potentially for competitors or irrelevant apps will appear before the item even when you search for the entire name of the app. This means that devs are incentivized to buy ads for their own name lest their competitor be listed first and if they don't you might well download malware.

On net the play store is 100% useless because of ads and poor search. The only way to adequately search for apps is by using an actual search engine, even googles, in your mobile browser to find apps and then using the play store solely for installation.

The play store is a product so bad if it wasn't required to install software it would have no users. It is the windows ME of google's product lines. It is so bad that Google ought to be embarrassed to show it off in public.
