Series Speed and conversion Part 8 of 8

A conversion audit: finding where people leave

Polishing a page nobody reaches is the most common waste. Walk the whole path end to end and the leak shows itself first.

This is the final part. So far we have traced how speed reaches revenue, read the numbers tools produce, cleared the weight off a page, and covered forms and experiments. The last piece is deciding where to apply all of it.

The most common waste is polishing a page nobody reaches. We look at the home page most, so we edit the home page most, while customers arrive on entirely different screens from search results and ads.

Step 1 — find the real entrances

An audit walks in this order — start without knowing the entrances and the rest is guesswork

Open the landing page report in analytics and the performance report in Search Console. Write down the top ten. They are usually not the home page, and often not the pages you considered important. That list is what you audit.

Read the queries alongside them. What people were asking when they arrived tells you what the page has to answer. For paid traffic, check that the promise in the ad matches the screen it lands on — a mismatch is the fastest and quietest cause of abandonment there is.

Step 2 — walk it yourself

A dashboard shows you where numbers drop but never why. So walk the path, and match the customer’s conditions while you do.

Use a real phone, on mobile data, logged out, in a fresh private window. A signed-in desktop browser on office wi-fi is not what a customer experiences. Go from entrance to completion in one sitting and note every point where you were blocked or hesitated.

Step 3 — classify the leaks

Six kinds of leak — the last is not something to fix but something to filter earlier

Start with actually broken. Submit the form for real, confirm the mail lands, confirm the thank-you page opens, take the payment step to the end. Faults of this class do not shave a little off conversion — they take it to zero. And because nobody reports them, they persist for months.

The last row, poor fit, is not a defect. Visitors who do not match your conditions leaving is correct behaviour, and stating those conditions early and plainly raises your completion rate overall. It is why we put the server-hosting requirement near the top of our own landing page rather than at the bottom.

Step 4 — fix one thing and measure it the same way

When the list gets long, pick the biggest hole on the path most people travel — the page traffic passes through, not the prettiest one.

Record the current value of that step before you touch it, then measure again over the same span under the same conditions. Where speed is involved, keep medians of three runs on the same URL from before and after. Record the items that did not improve as well — selective reporting costs you the credibility of every other number the first time it is noticed.

Closing the series

One principle ran through all eight parts: stop quoting other people’s numbers and produce your own — same URL, same conditions, median of three runs, once before and once after. That single habit turns a marketing report from an argument into a decision.

If the speed work itself is hard to do in-house, our optimization program handles upgrades, performance work, SEO support and a security review as one job, and hands back before-and-after measurements as a report. Exactly how that work runs is published on the process page.

A front-end budget you can actually hold

Pages do not get heavy in one go. They get heavy through small, individually reasonable additions. A ceiling you actually check is what stops the accumulation.

The cost of pop-ups — search and conversion at once

An interstitial that covers the content on mobile is treated unfavourably in search, and the same interstitial costs conversions too. The levers are timing, trigger and dismissal.
