1 Slow Site
Loads of unnecessary graphics or just a slow host will dramatically decrease your blogs readership.

2 Advertising overload
Any site that bombards the visitor with ads; popup or otherwise is just a major turn off.

3 political statements
Unless your blog is all about politics, a political or religious post can alienate your readers

4 Rambling
The blogger that has no topic but blogs anyway. Or worse the blogger that has a million unrelated topics.

5 Bad design
With a blending mixing of colors or unreadable font, who can read anything wrapped in such squalor.

6 Ranting
Nobody wants to read someone’s complaints.

7 Bad or missing navigation
If you can’t find it, can you read it?
