1. Too many ads.
Blogs with different content can place ads at different levels, but there is always a limit. Too many ads will drive readers away. If a reader comes to your blog and finds no worthwhile content to read, they will likely leave feeling disappointed.
2. Overly frequent updates
Some blogs are updated too quickly, posting dozens of new articles in a single day. Personally, I don’t like such blogs—not because they’re bad, but because it’s impossible to keep up, which creates a sense of frustration.
In fact, every blog should have an appropriate update frequency relative to its content and audience. For more details, please refer to my other articles about update speed (here).
