I was creating a new site today, using WordPress, and inserted some Adsense code into the front page post.
Ads were showing fine and very targeted to the site topic. Then I started playing around with the WP theme, modifying the colour of the post font to make it a slightly light shade (instead of black)....
Next time I refreshed the page, my Adsense block was showing Public Service Ads!
It's a few hours on now, and it's still not showing the correct ads.
Will this correct itself soon?
I should add that my site isn't about anything dubious or illegal or 'adult' in nature.
