Firstly i assume Poopelsa is Puppy logged in using an alt's account. Below is my reply to you based on your last comment:
I think the issue here is not so much if your product is making the front page or not, but whether the search will return relevant items based on the search terms. I have tried searching for "kemono bikini" like you said and all of the results appearing on the first page is relevant (bikini for Kemono) and IMO I dont think they are of lower quality like you described anyway. On the other hand, try seaching for the same term in the current search, and it does not take an observant person to realize that half the results are only derivations of the term bikini (namely panties, undies etc.), which is not as relevant. Would you go to the department store to shop for bikini and ended up buying panties instead? Hopefully not (no puns intended).
In any case, why would any normal person selling non kemono bikini bother to put "kemono bikini" into their product title? Even if it makes them appearing first, the chance of it leading to any sales is close to none. Eventually those sellers will have to readjust their title if they want to make sales. LL cant really control what all people put into their title text.
And in my years of doing SEO, what I have learned is that the relevance of the search term to the title meta tag is one of the most important criteria used by google search engine. So what is so wrong in placing importance on the title text?
