Why your ads stopped working
A campaign that was producing enquiries goes quiet for a fortnight and the instinct is to change everything. That is usually the worst response, because most of the causes are identifiable and half of them are not the campaign at all.
First, check it is real
Two weeks is not a trend in a business doing fifteen leads a month. Random variation alone will produce quiet fortnights regularly, and reacting to them is how good campaigns get broken.
Compare the same period against the previous three months rather than against last week, and look at whether spend also fell. If spend dropped, the platform is telling you something; if spend held and leads fell, something changed in the response.
Creative fatigue
In a small county you can exhaust your audience quickly. The same advert shown to the same twenty thousand people for three months stops working, and frequency in the reporting will show it climbing.
The fix is new creative, not a new budget. New photographs of recent jobs are usually enough; it does not need to be a rebrand.
Something broke
Forms stop submitting. Tracking gets removed in a website update. A phone number changes. A landing page starts returning an error on mobile only.
This is more common than people expect and it is invisible unless somebody checks. Submit your own form once a week; it takes a minute and it catches the most expensive failure mode there is.
- Submit your own lead form and confirm the email arrives
- Ring your own number from a mobile
- Check the landing page on a phone, not a desktop
- Confirm the ad account has not been restricted or the card declined
- Check whether a competitor has started bidding hard
The market changed
Seasonality is the obvious one, and it is sharper in Ireland than people allow for. A new competitor bidding aggressively is another, and it shows up as rising cost per click rather than falling impressions.
Both are real and neither is fixed by panicking. Seasonality is planned around; a new competitor is answered with better conversion rather than a bidding war you may not win.
Or the follow-up slipped
The most common cause of a campaign appearing to fail is that enquiries are arriving and not being answered quickly, so fewer turn into jobs and it feels like fewer leads.
Check the leads received, not the jobs won, before concluding the advertising stopped working. They are frequently different problems.
