I think this is a neat idea. A lot of people are gateway'd into anime through shows like My Hero Academia and Attack on Titan, so finding anime similar to what they enjoyed can slowly lead them into more anime. I'd imagine someone picking up Black Clover after My Hero Academia or Fairy Tail wouldn't be disappointed at all. (aside from Asta's screaming, of course)

One thing that might need to be considered is that some themes are just not connectable. For instance, mecha is a very broad genre, and recommending Neon Genesis Evangelion or Code Geass after watching Darling in the Franxx just doesn't make sense to me. Also, anime like Clannad and School Days have a scary amount of similar tags. This could be remedied with a user vote option that shows how accurate a recommendation would be. (Something like "56% of users agree with this suggestion.")

Another approach could be indicating why a show is being suggested. For instance, I would not say Katanagatari and the Monogatari Series are similar in aesthetics, themes, or even pacing. However, I could still recommend Katanagatari after someone has enjoyed the Monogatari Series because the source material for both of them are written by Nisio Isin. So, next to the suggestion would be something such as, "Written by the same author." 

Overall, I still think anime suggestions are a good idea, but automated systems without transparency can be an issue.

Of course this would be assuming @Ryan Dave Jimenez's site supported user accounts, otherwise it would need to either pull that data from an outside source or rely on anonymous submissions which can sometimes be problematic if bots or trolls get invovled. Otherwise I think this would be far more accurate than associating anime using keyword tags or something similar. Alternatively you could put in the legwork and do the research and manually add the recommendations (again, sourcing from another website I would think.)

Yeah I was thinking doing this all via algorithms.

But you guys make a good point about bringing in human intervention. Whether it be via voting or what not.

I've seen how other anime sites do their recommendations. And they are definitely user driven. Sadly my website isn't that populated with devoted users yet. Many just pop in for a minute or two to check on an anime's score. Which is fine as I planned to create a reference site. Not really a community site where you stay for hours.

But I'm definitely gonna weave your suggestions in. Thank you for the feedback!

So now you’ve reached the goal of sorting the anime by genre, have you also ranked them in those categories like you planned?

Yup I will. It would be cool to see which show is the best in each genre.

I'm still working on it though. I tried to do it one way and realized it won't work so I have to do it a different way. haha

I hate it when I don't think things through
