Website slow on mobile
Find one shared bottleneck. Apply one reversible performance patch.
SignalMend baselines two representative pages, traces the shared render path, and repairs the highest-impact common cause without turning a focused pilot into a redesign or replatforming project.
$49 diagnosis · $149 first repair pilot · starts after funding and access
Good first-pilot signals
- First paint is noticeably slower on phones and tablets than on desktop.
- A shared script, stylesheet, font, image, or cache policy blocks every page.
- Scrolling or loading causes visible layout shifts on common mobile widths.
- The team needs before-and-after evidence and a safe rollback, not a guessed score promise.
Included
- Lighthouse or WebPageTest baselines for two representative pages
- Network, render-blocking, cache, asset, and layout-shift diagnosis
- One maintainable site-wide code or configuration patch
- Checks at agreed phone, tablet, and desktop breakpoints
- Before-and-after report plus a written rollback step
Not included
- A redesign, framework migration, hosting move, or full-site rebuild
- Multiple unrelated performance fixes hidden inside one pilot
- Paid CDN, monitoring, plugin, theme, or optimization-tool purchases
- A guaranteed Lighthouse score, ranking, conversion, or revenue result
- Production changes before backup, funding, access, and baseline approval
Acceptance
A repair is complete only when the evidence is repeatable.
- 01The original mobile baseline is saved with the agreed page, device profile, network profile, and test tool.
- 02The patch changes only the named shared bottleneck and retains a documented rollback path.
- 03The same test setup produces a before-and-after report for both representative pages.
- 04The agreed breakpoints keep their content, controls, scrolling, and layout without a new visible regression.
Relevant evidence
Live lightweight calculator shell
A self-initiated responsive implementation demonstrates semantic HTML, plain CSS, local vanilla-JavaScript math, version-pinned assets, and static deployment. It is implementation evidence, not a client performance result, Lighthouse improvement claim, or guarantee for another codebase.
