Google Adwords and including your phone number

I setup a new adwords account and an option is to include your phone number in the ad. Google Adwords help line is closed on the weekend so I’ll ask here.

If a user doesn’t click on the ad and calls the number, how does Google track and charge the adwords user?

Another thing – I already get at least one call per week from salespersons trying to sell me what is usually a useless or overpriced product related to my business (real estate). I’m thinking adding my phone number might just result in more sales calls.

Any feedback from Adwords users?

AdWords Ads Often

I realise I post a lot of threads here, and I apologise for it, but I need some advice.

How often should you change your Google Ads adverts?
I am trying to design a new campaign structure, with an emphasis on leaving it alone to bring in enough data to properly analyse it.

I know that by making frequent changes to bids or budgets, the eventual results you get will be skewed.
But does creating new adverts do the same thing?

Should I create one set of adverts and leave them for a month before making changes?
Or can I remove any under-performing adverts once they reach a certain number of impressions?

My main concern is messing up the data the campaign gathers, but also I obviously don’t want underperforming advetrs staying in the campaign longer than the need to.

The internet is annoyingly vague on this topic, and I can’t see anywhere a suggestion of how often to change adverts for new ones.
So does anyone here have any advice?

Thanks in advance!
