Well after the whole Micheal Jackson scare my ads away and give me PSA's, I'm getting them again and I can't figure out why. Funlaws.blogspot.com It's only on that site.
content content content, and relevant content. If ads are not available for what you write about then write about something else.
That doesn’t mean anything. You can have ads one minute and the next their gone. From personal experience when the site/blog is new they tend serve a lot of public service ads. After a few months it gets better. Anyway that’s what I’ve noticed on my blogs/sites.
This is actually common with blogs. One of my blogs can't seem to get any ads on the fornt page (it's always blank, because I use the collapsible unit), but the interior pages all have relevant content. I really can't explain it, either. Ads seem to come and go.
Why don’t you use the space to promote your other blogs/sites? That’s what I do. I personally think it’s better than having public service ads or black spaces.
When it comes to blogs, I try to have as few ads as possible. I only have one adlinks unit at the top on the front page, and a 336 box at the bottom of my articles. I don't want to ruin the reading experience with ads.
