10 guides
  1. 01

    Read a response-speed measurement in context

    Compare response time, fetched HTML size and redirect counts under consistent conditions. Distinguish URLTO's server fetch from browser rendering and Core Web Vitals measurements.

  2. 02

    Distinguish response-fetch time from screen loading

    The speed check measures one server request. Do not report it as the time a visitor’s screen takes to finish.

  3. 03

    Distinguish response-body size from total page weight

    Body size is data from that request, not the sum of all linked images, fonts and scripts.

  4. 04

    Account for redirects in response measurements

    Short and final URLs have different request paths. Record included redirects when comparing them.

  5. 05

    Compare one response with repeated observations

    The same URL can vary over time. Record spaced observations to avoid overinterpreting one figure.

  6. 06

    Record results with differing cache and cookie conditions

    Your browser and the inspection server do not share identical cache or cookies. Distinguish request conditions when reading timing differences.

  7. 07

    Distinguish quick login or error-page responses

    First verify that the quick response belongs to the intended page. Do not compare a restricted view as content performance.

  8. 08

    Distinguish body-per-time ratios from connection speed

    The transfer reference is received body size divided by elapsed time. It is not an internet connection-speed test.

  9. 09

    Choose browser follow-up checks after a response test

    Follow server observations with actual page use. Start with suspected images, scripts or UI behavior.

  10. 10

    When a website check fails: interpret the error in context

    Distinguish target restrictions, connection failures and unexpected HTML in website, SEO, link and response checks. Understand why a server fetch can differ from your browser.
