Multiple Ads

Can I have some advise please

I have just learnt about having more than one ad in the ad group and have subsequently created another ad which I think is more clickable than the original. I have ad optimization turned on but even though the new ad has a higher click through rate it is only being served 3% compared to 97% on the original. I tried turning ad optimization off to see if it would display it more but no joy yet.

My question is my new ad has now a higher CTR than my original one (and the clicks are costing less) - should I just delete the original ad? The reason I am not sure is that it has been running fairly succesfully for months but am worried if it loses its fairly decent history and fair site numbers of clicks.

Just track the CTR for the original ad. If it goes down then you should delete it.

well the original ad hasnt gone down as such has been steady at 2.1% CTR for months and gets alot of sales but my new ad has a 10% CTR (admittedly it has only has 10 clicks compared to 10000 on the original). Would it still be ok to delete the original? My worry is there is some formula in the ranking that takes into account the ad group history and amount of clicks and by deleting the original the new one might drop down?

You need to give it at least 35 impressions, statistically, before the CTR can be considered valid, and there's also the fact that it can take several days to a week to be approved for the partner network. I'd give it a few more days, maybe a week, and see how the CTRs stack up then. If you do delete it, write another one to try to beat the control. Test those, and repeat.

if the new ad is better as you say, then in time it will get more impressions based on the ctr

i would leave both there

The 'date range' that you have set also includes how often the ads are shown. If your date range is longer than both ads were live, then the older ad will have a higher serve % as it was the only live ad for part of that period.

If you change your date range to when both ads were live the entire time, that might fix the issue you're seeing.
