Why your Facebook ads stop working after a few weeks

You launch a new Facebook ad. The first couple of weeks are great. Enquiries come in, the cost per lead looks good, and you think you've cracked it.

Then it slows down. Same ad, same budget, fewer enquiries. The cost per lead creeps up.

Nothing's broken. Your ad is just tired.

What Facebook ad fatigue actually is

Say you're a cleaner in Northampton, showing ads to homeowners within ten miles. That's a fixed pool of people. Spend money every day and Facebook shows your ad to the same people again and again.

The first time, someone notices it. The third time, they scroll past. By the sixth time, they don't even see it. Some get annoyed and hide it.

That's ad fatigue. It hits local businesses harder than big brands, because your audience is small. A national brand can keep reaching new people. You've got Northampton.

How to spot it

You don't need anything fancy. In Ads Manager, look at the last few weeks of one ad and check three things:

• Frequency. How many times, on average, each person has seen your ad. Once it creeps past about 3, keep a close eye on it.

• Click-through rate. Fewer people clicking than in the first week or two.

• Cost per lead. Going up, even though you haven't touched the targeting or budget.

If all three are moving the wrong way together, it's almost certainly fatigue.

I'll be straight with you: those numbers are rough guides from people who run a lot of ads, not rules from Meta. Every account is different. What matters is the trend.

Refresh it without starting again

The good news is you usually don't need a whole new campaign. You need the same message, looking new.

Change the first line. The opening line is what people actually read. Write three new versions with the same offer and test them.

Change the photo. Same offer, different picture. A real job you did in Wootton will beat a stock photo every time.

Add some movement. Our eyes are drawn to anything that moves. Meta's own creative team recommends turning still images into short animated ads: a little motion, the key benefit, then a call to action at the end. You can do it in Canva in ten minutes.

Try a short video. Fifteen seconds of you on a job, phone in hand, talking to camera. It doesn't need to be polished. It needs to look real.

Keep the offer. If it was working, the offer is fine. Don't throw away what works just because the picture's gone stale.

Plan for it, don't react to it

The best fix is to stay ahead of it.

Run two or three different ads at once, so Facebook can share the spend between them and find which works for who. And have a new one ready before the old one dies.

For most small local accounts, something fresh every four to six weeks is a sensible starting point. If you spend more, or your area is small, you'll need it more often.
