Ask for website speed reports you can compare

Check the first visit as well as the familiar office browser

Keep links from moving when pictures arrive late
A late image can push a link downward just as a visitor tries to tap it. Slow connections expose accidental navigation caused by movement rather than by…
Keep links steady while the website's font loads
A late-loading font can change line lengths and move buttons just as visitors try to press them. Slow connections reveal a jump that is invisible in cached…
Keep website add-ons useful and dependable
Chat boxes, maps and booking panels each have a purpose, but adding them everywhere can make a page harder to use. List what each one helps visitors do and…
Make a performance fix reach the whole affected page family
The supplier optimises one article but similar pages still use the older implementation. Ask whether the repaired behaviour comes from shared code or a…
Make loading placeholders lead to a clear outcome
Grey skeleton boxes can resemble empty cards or broken page content. Visitors may wait indefinitely because nothing explains what is loading or whether…
Make visible buttons honest about when they are ready
A page can display a booking or search button before the scripts needed to operate it have loaded. Early clicks appear to do nothing, so visitors repeat the…
Measure the delay your team actually reported
A manager reports a specific slow action, while the supplier focuses on improving an unrelated headline score.
Prioritise slow pages by the task they interrupt
A rarely visited archive scores worse than a heavily used service page with a different practical delay. Prioritise with the affected task, audience and…
Require a fair before-and-after performance comparison
The before test uses a slow mobile profile while the after test uses a different device and network setup.
Review the cost of additions after the website launches
The website meets its initial target, but later marketing additions accumulate without any release review of their cost.
Test the pages visitors actually use, not only the homepage
A performance report tests only the homepage, while the busiest service and article templates carry different assets and scripts.
Treat missing visitor performance data as an evidence gap
A performance tool lacks page-level visitor evidence, and the team treats the absence as a pass. Missing evidence is not a positive result. Ask whether…
Use clear photographs without slowing the page
Large original photographs are useful for editing, but a website usually needs versions sized for where they appear. Ask your supplier to prepare those…
Weigh a widget's usefulness against its measured delay
A supplier recommends removing a widget without identifying which business function would disappear with it.
