You can pour budget into great ads and still see disappointing results if the page behind them lets visitors slip away. These are the leaks we spot again and again — and how to fix each one.
Why do landing pages leak conversions?
Landing pages leak conversions when they add friction or doubt: forms that ask too much, buttons that are hard to find, slow load times, copy that does not match the ad, and nothing to build trust. Each gives a ready-to-act visitor a reason to leave instead.
The five mistakes that quietly kill ROI
Most underperforming pages share the same handful of problems:
- 1Asking for too much information before any trust is built
- 2Burying the call to action below the fold where nobody scrolls
- 3A slow page that loses impatient mobile visitors
- 4Generic copy that ignores the specific campaign or audience
- 5No social proof to reassure a first-time visitor
Mistake 1: forms that ask for too much
Every extra field costs you conversions. Research from Baymard Institute consistently shows that shorter, simpler forms complete at higher rates. Ask only for what you genuinely need to follow up — often just a name, email and phone number.
Mistake 2: a hidden call to action
If visitors have to hunt for the next step, most will not bother. Keep your main call to action high on the page and repeat it as people scroll. The anatomy of a landing page that converts covers exactly where it belongs.
Mistake 3: a slow, clunky page
Paid visitors are impatient, and most arrive on mobile. A page that loads slowly loses them before your offer even appears, so treat page speed as part of the page job, not a technical afterthought.
Mistake 4: copy that ignores the ad
When your page does not match the ad that brought the visitor there, they feel they are in the wrong place and leave. According to Google, landing page experience also feeds your ad Quality Score — so a mismatch quietly wastes your ad budget twice over.
Mistake 5: no social proof
A first-time visitor has no reason to trust you yet. Reviews, ratings, results and recognisable logos close that gap. Building proof into the page is a core part of effective landing page design.
Fix one mistake at a time
Resist the urge to change everything at once. Fix one issue, measure the impact, then move to the next. This disciplined approach turns a leaky page into a reliable lead generator.
Frequently asked questions
What is the most common landing page mistake?
Asking for too much information in the form. Every extra field reduces completions, so requesting only the details you truly need is usually the fastest way to lift conversions.
Where should the call to action go on a landing page?
Keep your main call to action high on the page, visible without scrolling, and repeat it as the visitor moves down. If people have to search for the next step, most simply leave.
Why is my landing page not converting?
Common causes are a long form, a hidden call to action, slow load times, copy that does not match the ad, and no social proof. Fixing these one at a time usually turns performance around.
Should each ad have its own landing page?
Ideally yes. Matching each ad to a page with the same message and offer reassures visitors they are in the right place, which lifts conversions and improves your ad Quality Score.
