Err...uh, the purpose of titles, covers, and synopses are for the reader to get 'curious' and pick/click on your work. Think of it as a whole, with each being a 'component' to reach your goal of clicking on your story. You can't just focus on one or two, and be done with it.
1) Like
@tiaf is trying to say, having a catchy/memorable title can help you get the clicks that you want. It's what the authors of long ass titles aim for, though many are panning them because of it. I'm not saying you resort to long titles, but having an 'interesting' title can make the reader click on your story.
However, do keep in mind that the title should have something to do with your work (most of the time).
2) Covers. Aside from a catchy title, the cover's purpose is to arouse curiosity in a reader whenever he/she glances on your work on the digital shelf. It's not just 'slap a picture of a pretty gal on the cover', you really have to think of a great artwork if you aim for serious retention on your readers.
What about the lewd anime-style covers? Well, they do bring the clicks (trust me, I've seen it do its share of wonders in my work), but once the reader realized they've been tricked, they'd drop your work faster than you can say "knife", along with an accompanying negative review to warn other readers (or simply just to piss you off) sometimes. And reader retention is what you need if you aim to sustain/grow your view count.
3) Synopses. This component gives the reader the idea of what to expect in your work, but you should also be careful not to bore them while reading your synopsis, or they'll also drop your work before they even clicked on your first chapter. Too few details, vague sentences, and off it goes to the proverbial 'garbage bin'. On the other hand, too many details, and it will also be the same. Just keep it in moderation.
A good synopsis should simply answer the questions:
1) Who is the character?
2) What is his/her problem?
Additional tips:
1) Consider the site where you upload your work. Yeah, I learned this the hard way. When I uploaded in RoyalRoad, I got low ratings, simply because my story got no sex, and/or system. I researched about that site and found out that most readers there prefer litRPGs, a genre I hated. The same can be said with ScribbleHub. Most of the stories here have smut, there's a vocal part of readers who hated 'harem' genre, and has a bit of bias against JPN-inspired stories. So I removed my 'isekai' story and uploaded the 'normal' romance novel I'm working on. My life is peaceful since.
2) You can't force a reader to click on your work. Views takes time. Let your story quality speak for yourself and your novel. What you can do as an author is to be patient and consistent in your updates.
Yes, your persistence in changing your 'introductions (title, cover, sysnopsis) may land you a few views, but focusing on those will be counter-productive in the long run. Especially if your potential readers had enough of your inconsistency.
In the end, I'm not saying I'm an expert to these things. I've only been writing for 15 years now, ten years of which went to willy-nilly writing. However, these suggestions and tips I've been sharing are my personal observations and experiences.
TL; DR? Yeah, at least I tried.
