A homeowner taps your ad or your map listing on their phone. Before they read a word, your page has to load. Then it has to answer three questions fast: do you do what I need, are you near me, and how do I reach you? If it doesn't, the back button is one tap away.
The research on how quickly people leave is older than you might like, but it keeps pointing the same way.
Speed Comes First
Google data found that 53% of mobile site visits are abandoned if pages take longer than 3 seconds to load. That figure comes from a sample of about 3,700 mobile sites measured in March 2016, so treat it as directional.
53%Share of mobile site visits abandoned when pages take longer than 3 seconds to load, from Google data on about 3,700 mobile sites (March 2016).
A later Google analysis predicted that as page load time goes from one second to ten, the probability of a mobile visitor bouncing increases 123% (Think with Google, 2018).
Bigger studies connect speed to sales, with a catch for lead-based businesses. In Milliseconds Make Millions, Deloitte Digital looked at mobile data from 37 brands and found a 0.1-second speed improvement came with 8.4% more conversions on retail sites. For lead generation sites the picture was mixed: visitors were 21.6% more likely to get from the first step of a form to the submission page, but overall lead-gen conversion rates dipped in that sample.
Google's current yardstick is Core Web Vitals. A page is in good shape when its main content loads within 2.5 seconds (Largest Contentful Paint), it responds to taps within 200 milliseconds (Interaction to Next Paint), and the layout doesn't jump around (a Cumulative Layout Shift of 0.1 or less), measured at the 75th percentile of visits.
Then Clarity, Within 10 Seconds
Once the page loads, the clock keeps running. Nielsen Norman Group found users often leave web pages within 10 to 20 seconds, and that "to gain several minutes of user attention, you must clearly communicate your value proposition within 10 seconds."
For a cabinet dealer, the first screen should show:
- What you sell, in plain words: kitchen cabinets, bathroom vanities, design and installation.
- Where you work: your city and service area.
- Proof: your Google rating, a real project photo or a short client quote.
- One clear next step: call, text or book a design consultation.
