The three parts of a slow tap
On dealer sites the first part is the usual problem. The tap itself is handled quickly; it just waited in line first.
| Part | What happens | Usual cause on a dealer site |
|---|---|---|
| Input delay | The tap waits for the phone to be free | Chat, tracking or a retailing tool still starting up |
| Processing | The site's own code handles the tap | A filter that rebuilds the whole inventory list |
| Presentation delay | The screen redraws with the result | A long inventory page with hundreds of elements |
What makes taps slow
A phone can only do one thing at a time on a page. If chat, tracking or a retailing tool is busy starting up when the shopper taps, the tap waits in line. The page looks loaded but ignores the shopper.
The fix is keeping that work out of the way when shoppers are tapping. Site Speed Engine loads the tools after the page is ready, so the first taps get answered.
