Hello I am new to advertising on the internet so maybe this is a dumb question. but I dont quite get this part.
Am I able to run an adwords ad with say a toll free number in it? wouldnt that defeat the purpose of having per click or pay per conversion as the business model?
Going from memory, I can recall seeing certain ads for consultants that were on a forum I visit. I dont know if they were adwords ads or just some sort of other affiliate agreement with that particular forum. So trying to use my own personal experience to reason this out is just confusing me more.
A related question would use of an 800 number in a series of related ads or websites cause any problems with google adsense or adwords. Liek lets' say I had a large portal type of site say Giantwebsite.com and then I set up a number of websites and landing pages all of them using the giantwebsite, each one a different business but htey all use the same toll free number. Would this cause any sort of banning or other problems?
To answer your first question, if you put a phone number in the ad and the person viewing the ad decides to pick up the phone and call instead of clicking on the ad itself, then you have gained a potential client without paying for the click. The potential downside is that your ability to track conversion becomes skewed. Try some ad groups with/some ad groups without (A/B) to test your response.
As an adwords advertiser I do post toll free number on a small percentage of my ads, on search networks only. I really don't see much difference in click-through rate for ads with 800 number and the ads without. As nimbledigit mentioned there is no way to track if customer actually called in instead of clicking through the ad. But I suspect the % of customers who would do that is quite small anyway.
