Performance Small

Keep an eye on performance

Performance regressions rarely arrive as one dramatic change: they accumulate one added image, one new tracking pixel, one un-lazy-loaded video at a time, until a site that was fast a quarter ago quietly isn't anymore, with no single commit anyone would think to blame.

Why it matters

Performance regressions tend to creep in one image or script at a time, so a fast site today can quietly slow down without ongoing checks.

How to fix

1 Re-run performance checks after adding new pages, assets, or third-party embeds.
2 Set a page-weight or load-time budget so regressions are caught early.

Common mistakes

Optimizing once at launch and never re-measuring as new pages, features, or marketing embeds get added later.
Missing regressions because only the homepage gets checked, while a heavier product or landing page template ships unmeasured.
Adding a third-party script "temporarily" for a campaign and never removing it once the campaign ends.

How to verify

1 Re-run performance checks after adding new pages, large assets, or third-party embeds, not just at launch.
2 Set a page-weight or load-time budget so a regression is caught by a number crossing a line, not by a subjective sense that the site "feels slower".
3 Periodically audit third-party scripts and keep only the ones still actually in use.
