Adsense showing Irrelevant ads on my site???

Hi all
I only just recently starting using adsense and its going ok, but i have noticed that on one of m sites which is about tropical fish tanks, there are a lot of adds showing that are about water tanks, and other irrelevent kids of tanks. Is there a way to stop this from happening?

 

Wait for few days and see, it takes some time to show more relevent ads
Besides, add more content

 

adding about 5 new articles each day, and this has been happening for over a month

 

Try to improve the quality of web site, then you will have most related ads. Wait few more days.

 

Inorder to get relevant ads, you could try-
1. Section Targeting - This method is to place special keywords between the most relevant content on a webpage. Google then, will use this content specificall to deliver more targeted ads.
2. Competitive URL filtering - to filter out urls from which ads are displaying in your site.

 

Before and after ur ad placement use some high paying keywords related to ur content. It would force contextual ad.

 

I know that adsense spiders are reading keywords form meta tags keywords, and the ads displayed will contain this keywords. Question: have you setup channels in your adsense account?

 

first possibility is that adsense has no enough advertiser for your niche.
second possibility is that its because your site is new in adsense.
