Fastest PSG Vendor Websites 2026 (Mobile Speed Rankings)

Most PSG vendor comparisons focus on pricing, features, and industry fit. Mobile website speed rarely comes up — but it’s one of the few signals you can verify yourself, without asking the vendor anything. We ran Google’s PageSpeed Insights across all 278 PSG-approved vendors on mobile to find out who leads the field.

What We Measured

Vendors covered: All 278 PSG-approved vendors active in April 2026.

Tool: Google PageSpeed Insights — the same free tool any member of the public can use at pagespeed.web.dev.

Device: Mobile. This reflects how most visitors browse and applies the stricter mobile scoring thresholds.

Score type: Lighthouse performance score (0–100). This is a lab simulation — a controlled test of how fast a site loads on a standard mobile device under standard conditions.

Important: This measures the vendor’s own marketing website. It does not measure the software product or platform they deliver to clients. A fast website and a well-built product are related but separate things.

Snapshot date: April 2026.

The Top Performers

Of 278 vendors measured, only 9 score 90 or above. Here are the leaders:

Achieving a perfect 100 on Lighthouse mobile is rare. It means the site loads near-instantly, responds to every tap without delay, and has no layout instability. These top performers have invested meaningfully in the experience their website delivers to mobile visitors — the remaining seven vendors all score between 92 and 99, placing them well above the field by a wide margin.

Context: How Rare Is This?

Only 9 out of 278 vendors (3.3%) score 90 or above. The other 96.7% score below 90 on mobile.

The median score across all 278 vendors is 47 out of 100. That means the vendors listed above are not marginally better than average — they are performing at roughly twice the median score. In practical terms, their sites are in a different category from the typical PSG vendor website.

This isn’t unique to the PSG list. The wider Singapore B2B market looks much the same — our sister site’s Most Singapore B2B Websites Fail Google’s Speed Test measures a broader sample and finds the same low median. The top performers above are genuine outliers against the country’s B2B web as a whole, not just the PSG subset.

What a High Score Actually Means

A Lighthouse score of 90 or above tells you three things about a vendor’s website:

It loads fast on mobile. The main content appears within about 2.5 seconds or less on a standard mobile connection. Visitors don’t wait and wonder if the page is loading.

It responds immediately to taps. When a visitor taps a button, opens a menu, or fills in a contact form, the page reacts within 200 milliseconds — fast enough to feel instant. Sites with poor responsiveness feel sluggish and unreliable on a phone.

It’s stable as it loads. Elements don’t jump around while the page finishes loading. Buttons stay where they are. Text doesn’t shift. Images load in place without pushing content down. This matters more than it sounds — unexpected layout shifts cause accidental taps and a frustrating experience.

A perfect score of 100 means a vendor has optimised all of these simultaneously on mobile, which takes deliberate effort and ongoing maintenance.

What This Means When You’re Comparing Vendors

Use it as a positive signal, not the deciding factor. A vendor who scores 96 or 100 on mobile has clearly invested in user experience on their own public-facing site. That’s a reasonable indicator of how they think about quality and attention to detail. It doesn’t tell you everything — but it tells you something.

The median score makes the top performers stand out. With the typical PSG vendor scoring 47 out of 100, a vendor in the 90s is genuinely exceptional by the standards of the field. This isn’t a case of splitting hairs between 85 and 90. These vendors are substantially ahead of their peers.

Speed is one factor among many. When choosing a PSG vendor, pricing, software features, industry experience, support quality, and category fit all matter more than website speed. Use mobile performance as one input in your comparison — a useful tiebreaker or a positive signal — but not the primary criterion.

Check vendors you’re already considering. You don’t have to rely on this list. You can check any vendor’s score yourself before your first meeting.

How to Check Any Vendor’s Score

Checking a vendor’s mobile speed takes about two minutes:

1. Go to pagespeed.web.dev
2. Enter the vendor’s website URL
3. Select the Mobile tab
4. Read the performance score (0–100) and the Core Web Vitals results

If the vendor scores in the 60s or above, they’re performing better than most of their PSG-approved peers. If they’re in the 80s or 90s, they’re in a small group of high performers.

You can also find the mobile performance verdict directly on Grantla’s PSG solution pages — it’s shown inline per vendor so you don’t need a separate lookup while you’re already comparing solutions.

A Note on the Data

This ranking is based on Lighthouse lab scores — controlled simulations, not live measurements of real visitor traffic. Lab scores are consistent and useful for comparison, but they’re not drawn from actual users visiting the site.

A separate dataset — the Chrome UX Report — captures real-user experience for vendors with enough public traffic. Vendors with high real-user traffic may have field data that tells a more complete story. Among the vendors who do have real-user data, fewer than 30% pass all three Core Web Vitals on mobile, which gives some context for how competitive the 100/100 lab score actually is.

Scores can also change as vendors update their websites. This is a snapshot from April 2026. A vendor not on this list today may well appear on it after a site rebuild.
