The driver to watch
For a SaaS, the driver is how fast the pricing page reacts
Visitors compare plans by tapping: monthly or yearly, seats, currency. Every tap that takes longer than 200 ms feels broken, and it happens right when they are deciding to pay.
What usually causes it
- Plan toggles and seat calculators built on heavy JavaScript
- Chat, analytics and A/B testing tags competing for the main thread
- The whole page hydrating before the first tap can respond

Where speed costs a SaaS money
Visitors decide on your marketing site, long before they see the product. These are the pages where they wait.
/pricingINP
Pricing page
Monthly and yearly toggles, currency switchers and seat calculators all react to taps. Heavy JavaScript turns a quick comparison into a wait.
/signupLCP
Signup and trial
Analytics, chat and testing tags often load before the form. The form is the one thing that has to show up fast.
/CLS
Homepage and landing pages
Cookie banners, logo carousels and product demos that load late push the call to action around.
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.

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 SaaS
Sample answers, from the kind of data a connected site produces.
Which channel lands people on our slowest page?
Paid search. It sends 41% of pricing page visits, and those visitors get 520 ms taps on mobile, against 180 ms on desktop.
Did last week’s release slow down signup?
Yes. The signup form went from 1.9 s to 2.8 s after Tuesday’s release, when a new chat widget started loading before it.
Should we fix pricing before the homepage?
Yes. Pricing gets a quarter of the traffic but sits right before 60% of paid conversions, so it carries $740 of the $1,450 at stake.

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.
