Page speed

Every page, tested.Every week.

Every published page is tested for speed on mobile and desktop each week, and again after you publish it. You see which pages are slow and what would make them faster. It comes with your website, so there is nothing else to set up.

  1. 01

    Every page, every week.

    Each published page and blog post is tested on mobile and desktop on your schedule, and again about ten minutes after you publish it.

  2. 02

    See what's slow.

    Scores from 0 to 100, sorted into good, needs work, and poor, with the timings behind each one.

  3. 03

    Know what to fix.

    Each slow page lists what would make it faster in plain English, with the time each fix could save.

By hand or by asking

Read it yourself, or ask what's slow.

Use the dashboard, or ask Lumi, Claude, or ChatGPT about your page speed in plain words.

Find your slowest pages

Open SEO, then Page Speed. Filter to poor pages, or sort slowest first, and switch between mobile and desktop.

Ask which pages are slowest. The agent reads your latest results and lists them with their scores.

The spring roof checklist is slowest at 46, then roof repair at 71. Everything else scores 89 or higher.

Find out why a page is slow

Open a page to see its timings, real-visitor data, its score over time, and what would make it faster, with a link straight to its editor.

Name the page and ask why. The agent reads its latest test and explains the fixes that would save the most time.

Why is the spring roof checklist slow on mobile?

Get page speed/blog/spring-roof-checklist
The main content takes 5.8 seconds to load. Loading the images below the fold later could save about 1.4 seconds, and removing an unused script about 0.6.

Test again after a fix

Publishing retests the page on its own. Press Test again for one page, or Test all pages for the whole site.

Ask for a new test of one page or the whole site, and read the results a few minutes later.

Also in page speed

More than one homepage score.

01

Mobile and desktop

Every page is tested both ways, so a page that is fine on a laptop and slow on a phone stands out.

02

On your schedule

Weekly by default. Pick every two weeks or monthly, the day, hour, and time zone, or pause it.

03

Retest after publishing

A page or post you publish is tested again about ten minutes later. Turn it off if you prefer.

04

Real visitors too

When Google has data from real Chrome visitors, it shows next to the test, for the page or for your whole site.

05

Fixes in plain English

Each suggestion says what is slow and why, and notes when BrightSite already handles part of it.

06

Up to 500 pages

Pages, the blog, and every post are tested. Past 500, your homepage and most visited pages come first.

07

180 days of history

See a page's score over time, so you can tell when a change made it faster or slower.

08

A failed test keeps your score

If one test fails, the last good result stays on screen with a flag, so one bad run never wipes a page.

On every plan

The same on every plan.

Page speed has no tiers and no add-on. Launch, Grow, and Scale test every page the same way, and so does the free trial.

Questions

About page speed.

What does the test measure?

Each page gets Google's Lighthouse performance score from 0 to 100, plus how long the main content takes to load, blocking time, layout shift, speed index, and server response. 90 and up is good, 50 to 89 needs work, and under 50 is poor.

How often are my pages tested?

Once a week by default. You can switch to every two weeks or monthly, pick the day, hour, and time zone, or pause it. Published pages are also retested about ten minutes after you publish them, and you can test all pages yourself once an hour.

Which pages are tested?

Every published page, your blog, and every published post, on mobile and desktop. Pages marked noindex are skipped. A site with more than 500 pages has its homepage tested first, then the pages with the most visits in the last 30 days.

Is this the same test as Google's PageSpeed Insights?

Yes. Every test runs through PageSpeed Insights. When Google has enough real Chrome visitors for a page, or for your whole site, that 28-day data is shown next to the test.

Why did a score change when I didn't change anything?

Scores move a few points from one test to the next, and third-party scripts can change on their own. Look at the score over time rather than one result. If a test fails, the last good result stays on screen with a flag.

Does page speed cost extra?

No. It is included on every plan, with the same limits on Launch, Grow, and Scale, and during the free trial.

Can an agent read my results?

Yes. Lumi, Claude, and ChatGPT can list your slowest pages, explain what would make a page faster, and start a new test of one page or the whole site.
