User blog comment:Dr. Unicorn/What Makes a Good Wiki Page?/@comment-1038387-20160606180530

Images help give a visual representation. If you go to a wiki about a TV series and you see a character name you don't know - like, say, Polliver - reading the description or history may take time, and not everyone is tempted to do that. Having an image makes it instantly recognizable as "oh, that guy". Also, these pages tend to show their images in the category and/or See Also sections, so they're more tempting to visit.

I think a very important thing to writing a good page is a standard across the wiki. Give all character pages the same sections, all episodes the same layout. Use one style tables and infoboxes throughout. Nothing grinds my beans more than going to a wiki and seeing vastly different design across pages. Sorry, Downton Abbey Wiki, the season tabbers are nice, but please use them on all character pages. Sorry, Stardew Valley wiki, your page on Sea Cucumber is not helpful. Even if you stub a page, stub it with section headers and templates.
