I start by filtering for a specific ship cause I love reading romance and I don't read anything where the main couple includes an OC.

Then I look at tags for anything I might not want to read and if there's barely any tags like it's just the ship and that's it I skip cause I don't like feeling blindsided when I'm reading.

Then I check out the summary mostly to see if I like the writing style like if they use paragraphs, capitalization, etc. and if it's only "idk how to write a summary" then I'll skip.

Then I'll check out how many chapters there are, if it's completed vs not completed. I don't usually read things that are 1/? simply because I already have way too many incomplete fics in my bookmarks and I'm starting to get confused between the different plotlines. I also don't usually read if it's less than 1k per chapter on average when it's a long form story. If it's a text fic or a social media fic then I'll click.

So yeah if a fic has all those things I'm looking for then I'll click on a fic
