i want to put adsense on the bottom of my wordpress blog. i use Glore as my theme. how to do this without using any plugin? Glore can be found here http://fthemes.com/glore-free-wordpress-theme/
It depends where you want to place the code. You can put it on sidebar.php, header.php, single.php, footer.php. It really depends
i want to put it on the bottom of every single post (above comment box) but i don't know where to exactly put the adsense code.
Personally I designed my own themes (which I have now released) to get the best conversion rates. Take a look if you are interested.
and if i want it to be on the begining of the post as well? the problem is that on categories or tag pages it will show a snipt of the ads, so if i have a category with 10 posts it will show 10 ads? thanks!
Yes that's true. If the issue leads here then you have to filter the loop on the category/tag pages that it won't show any ad codes.
