The best way to change lots of ads?

My site has lots of pages. If I want to add channels to all my pages or make other changes to all my pages, do I need to copy the new code to every page manually or is there an easy way?

 

You can try using URL channels.

 

I added the code with a channel number to my first page
http://articles-online.info
but the codes on my other pages are without a channel number. Will this still work, or do I need to add the number to all my pages?

 

there are channels on your web site. you can see

google_ad_channel = "2766842941";

in your adsense code. it shows the channel numbers

 

Do I need the code on all my pages if I want them all to be tracked, or is it enough that I have it on my index page? If I need it on all my pages, can I use a search and replace program?

 

Channels works like this. It is quite useful to locate the ads that are being clicked.

Let's say you have three adsense ad's on your index page.

[header ad]
[sidebar ad] [content ad]

make a new channel for each of this position. call it index_header, index_sidebar, index_content.'

and suppose you have a different page called info.html with the same 3 ad's locations.

make channels and call it info_header, info_sidebar, info_content.

when a user clicks a ad on the sidebar in the info.html page, than info_sidebar would count the click. when a user clicks an ad on the content of the index page, index_content would count the click, and so on.

 

no you dont...cause channel IDs are already in your google ads code...
