There is no one easy failsafe tip. Have a lot of content, don't have a lot of competitors. Depends on what your wiki is about and what the google search is.
As Tupka217 said, there is no guaranteed checklist. However, there are some general guidelines. To expand a bit more on what Tupka217 said, have lots of content. However, don't have too many short pages and don't have really long pages. Generally, all text is better than all images but, ideally, each page should have a mix of both. Do not unnecessarily repeat content on different pages. Try to cover a topic that does not have too many other sources already on the internet; especially other wikis. Of course, it helps if your wiki is about something a lot of people care about. In other words, it helps if you wiki is about something popular.
Edit: It also helps if the wiki looks good and is easy to navigate; both on desktop and on mobile. Although, there are claims that Google focuses mostly on mobile.
