I manage several community events calendars and write about local events, so I’m regularly visiting the same websites over and over again, or at minimum, on an annual basis. One mistake that I often encounter is that the organization or business changes its website page structure.
For example, the webpage for a particular event was previously located as a subpage under the Events page. Now, it has been moved to Community > Happenings. What the organization or business inadvertently did was 1) create broken links for every website that was connecting to the previous link structure and 2) hurt its search engine rankings.
Global and national brands are guilty of this mistake, too, as I have discovered that they changed the links to the subpages of their franchises. Unless you’re fixing a terribly designed website page structure, there should be no logical reason to alter it.
In addition, if you have a recurring event, you should create one page dedicated to it and then update it as the event approaches. In other words, don’t create “Fun Event 2022” only to then create a new page “Fun Event 2023” the next year and so on. You can easily put historic information (e.g., photos, winners, awards, speakers, etc.) on that main page (e.g., “Fun Event”), which you should treat as a microsite.
