Find out how many members your slow join page turns away
Every new member pays again next month, so a lost signup costs more than one payment. SIUX Studio ties the speed of your join, pricing and checkout pages to the members they bring in.

The driver to watch
For a membership, the driver is how fast the join page loads on a phone
People join on impulse, from a post or an email. A join page that makes them wait loses the impulse, and a lost member is every monthly payment they would have made.
What usually causes it
- Intro videos and testimonial walls above the price
- Community platform scripts loading on public pages
- Fonts and images that hold up the first screen

Where speed costs a membership money
People join on impulse, often from a post or an email on their phone. These are the pages where that impulse fades.
/joinLCP
Join page
Join pages lead with a video or a wall of testimonials. If the first screen takes seconds on a phone, the visitor never reaches the price.
/checkoutINP
Checkout
Monthly or yearly, coupon codes, add-ons: each choice is a tap that has to respond at once.
/pricingCLS
Pricing and plans
Review widgets and comparison tables that load late move the plan buttons as people reach for them.
What we measure
Five signals, and what each one costs you
Speed metrics on their own are trivia. Each one below is tracked per page and tied to the sales that page brings in.
0.1s
Faster on mobile was enough to lift retail conversions by 8.4% in the Deloitte × Google study.

What a faster join page is worth to you
Use revenue from new members only, since members who renew add to it every month. The assumption behind every figure is spelled out below.

Assumes, for every 0.1 s faster, +1% more conversions and +0.4% more visitors (fewer people give up before the page loads, plus a light Google ranking boost), both halved below 2.5 s, with visitors capped at +10%. Deloitte × Google measured +8.4% conversions for retail from 0.1 s, so this is conservative. Your real report uses your own visitors and orders.

Ask the report
Questions the report answers for a membership
Sample answers, from the kind of data a connected site produces.
How many members did slow pages cost us last month?
About 18 new members, or $700 a month in recurring revenue, based on how visitors who got a fast join page converted.
Do monthly or yearly plans suffer more?
Monthly. People who pick monthly are mostly on phones, where the plan picker takes 410 ms to react.
Which campaign sends people to the slowest page?
The podcast link. It lands on a version of /join with a second video player and takes 4.6 s on mobile.

Fix #1 first: the hero image on /checkout is 1.8 MB and loads after two third-party scripts.
Then the alerts do the rest
Every signal flows into one place. When a deploy, a new app or a theme change makes things worse, you hear about it the same day, with the page and the price.
Deploy watch — A new release is compared with the week before it. If a page gets slower, you get an alert naming the page and what it now costs.
