URL tracking and Quality Score

Does adding tracking codes to existing KW and Ad URLs affect QS?

[NatronZero]

And my question is this... if I have an account running for some time and then want to add, say a call tracking solution and have to add a tracking ID to each URL, will this change the properties of an ad or keyword - will Google see these as new KWs and ads? The URL is the same.. so on one hand I would say no, on the other hand I'm not sure how stringent the policies are... I have removed a "www." from a display URL, and this showed as a different ad.

Thanks,
n.

This will cause Adwords to re-evalutate the landing page, but I doubt it will cause any issues if you're not breaking any of their rules.

Changing the click URL will cause Adwords to handle these urls as new, you will loose all your history. So never change old ads, but add the new ones and wait with disabling until the new ones proved their value.

Sujan: Quality score is an attribute of the keyword, with the text-ad and landing pages being contributing components. When you say that changing the target URL will cause them to 'loose are thier value' what are you specificially talking about? Are you saying Google will re-evaluate the text ad or the landing page or something else?

can you further clarify?

do you mean the actual url (sales.store.com) or the display url (blue-widgets.store.com)?

does QS track history on the actual or display url or both?

When you apply new URL to a keyword level, your ad(s) do note get re-evaluated.

No reason to lose anything if you change

google.com

to

google.com/?something

as long as it is absolutely the same landing page.
