Choose the Page You Want to Test

Pick the page people see after they click your ad.

This may not be your home page.

It may be a page for one service or one offer.

1. Open that page.
2. Copy the full web address at the top of your browser.
3. Make sure the address starts with https://.

Use Google PageSpeed Insights

1. Open Google PageSpeed Insights ↗.
2. Paste your web address into the box.
3. Click Analyze.
4. Wait for Google to finish the test.
5. Click Mobile at the top of the results.

You will see a large score in a circle.

That is not the number we need.

Look for Largest Contentful Paint

Move down the page until you see Largest Contentful Paint.

You may also see the letters LCP.

They mean the same thing.

Write down the number of seconds.

• 2.5 seconds or less: Good
• More than 2.5 seconds: Needs work
• More than 4 seconds: Slow

Run the test three times.

Write down all three LCP numbers.

Use the number in the middle.

Do not use the fastest number.

Put Your Number Into the ADR Terminal

Open the ADR Capital Leakage Terminal.

Find the control named Mobile Render Latency.

Set it to your LCP number.

Then fill in these four boxes:

• How much you spend on ads each month
• How much one ad click costs
• How much one sale is worth
• How often your leads become sales

The calculator will show how a slow page may waste ad money and sales.

These numbers are estimates.

They are not a promise of future sales or profit.

See If Your Page Gets Faster

Save your first test numbers.

Test the same page again after the page is improved.

Use the same steps each time.

This will show you if the work helped.

The goal is simple: help more people reach your page before they leave.
