Most of this is images that were never resized, a page builder, and six plugins doing one job. It is fixable in an afternoon by somebody who knows where to look.

The retention curve here is a working model of well-documented mobile abandonment behavior, not a measurement of your site. Run PageSpeed Insights for your real numbers.

What this assumed

  • Uses a conversion penalty that grows with load time. Your real curve depends on your audience and your offer.

Runs in your browser. Nothing you type is sent anywhere.

This is an estimate

This tool returns an estimate based on the numbers you entered. Your real result depends on your own costs, rates and conditions. Check it against your own records before you make a decision with it.

What this tool actually does for you

Who it is for

Anyone whose site was built on a page builder loaded with plugins and sliders.

The problem it points at

Your site takes six seconds on a phone in a truck on rural data. A big share of visitors never see it at all.

What you walk away with

The revenue tied up in load time, so speed stops being a nerd argument.

How to use it

Takes about two minutes. Be honest with the numbers, the tool is not going to tell anybody.

  1. Test your site on PageSpeed Insights and get your real mobile load time.
  2. Enter your monthly visitors and what a customer is worth.
  3. See what each second is costing you.

Put this tool on your own website

Free forever. I host it. You keep it.

This is a real lead magnet you can run on your own site tonight. Somebody lands on your page, plays with the numbers, sees what their problem costs, and now they are on your website instead of a competitor's. Costs you nothing, and I keep it working.

  1. Scroll up and press Put this tool on my website. The code appears right there, no form.
  2. Copy the one line you get.
  3. In your website editor, add an Embed, HTML or Custom Code block on whatever page you want it on.
  4. Paste it in, save, publish.
  5. Check it on your phone, then send people to that page.

Works on

WordPress, Wix, Squarespace, Shopify, GoDaddy, Webflow, Duda, HubSpot, ClickFunnels, or plain HTML. Anywhere that takes an embed code.

What it costs you

Nothing. No monthly fee, no expiring trial, no watermark you have to pay to remove. If you get stuck putting it in, text me at (903) 500-8898 and I will help you place it.

One useful tool is the proof

Now imagine the whole website doing real work.

Map the pages, lead capture, follow-up, and reporting that should sit behind your offer. The result is a recommendation, not a guaranteed outcome.
