Results by builder
Which landing page builder is fastest for Google Ads? Everyone has an opinion. We wanted data. So we tested 58 public pages built on 8 builders with Google PageSpeed Insights on mobile, all on the same day. Here are the medians (ClickMend scans, October 2026, 58 pages):
| Builder | Pages | Median score | Median LCP | Median TBT | Median CLS | Median weight |
|---|---|---|---|---|---|---|
| Wix | 7 | 66 | 10.1 s | 54 ms | 0 | 2,787 KB |
| Squarespace | 7 | 60 | 8.6 s | 135 ms | 0 | 1,771 KB |
| WordPress + Elementor | 8 | 59 | 10.3 s | 36 ms | 0 | 2,467 KB |
| Webflow | 7 | 60 | 6.0 s | 116 ms | 0 | 1,718 KB |
| Unbounce | 7 | 75 | 5.9 s | 400 ms | 0.003 | 1,337 KB |
| ClickFunnels | 7 | 40 | 18.0 s | 535 ms | 0 | 3,413 KB |
| Leadpages | 8 | 52 | 13.3 s | 678 ms | 0.005 | 3,062 KB |
| GoHighLevel | 7 | 32 | 5.7 s | 853 ms | 0.338 | 3,196 KB |
Score is the PageSpeed performance score, 0 to 100. LCP is Largest Contentful Paint, the time until the biggest thing on screen shows up. TBT is Total Blocking Time. CLS is Cumulative Layout Shift. All are lab numbers on a simulated phone.
The spread inside each builder was wide. Unbounce pages went from 42 to 95. Leadpages went from 28 to 76. GoHighLevel went from 27 to 69. That spread is a reminder that what goes on a page matters as much as the tool.
How we tested
- Pages. For Wix, Squarespace, Webflow, and Unbounce, we used published template demos from each builder's own template gallery or marketplace. Elementor's own demos blocked our test, so we used 8 published demos of Elementor template kits for home service trades. ClickFunnels, Leadpages, and GoHighLevel did not offer testable template demos, so we used each company's own landing pages, which are built on its own tool.
- Builder check. We read each page's code and confirmed the builder from its signature files before testing.
- Test. Google PageSpeed Insights API, mobile, performance category, one run per page, on October 23, 2026. 60 test calls in total, including one blocked page we threw out and one failed run we repeated.
- Privacy. No client pages and no small business pages were used.
Read these limits before you quote any number:
- 7 or 8 pages per builder is a small sample. A different set could move a median.
- These are demos and vendor pages, not real ad pages from advertisers.
- The page types differ. The ClickFunnels, Leadpages, and GoHighLevel pages, and the Unbounce previews, carried their makers' own tracking tags. Tag and pixel script was a median 829 KB per Unbounce page, 1,527 KB per Leadpages page, 999 KB per GoHighLevel page, and 355 KB per ClickFunnels page. The Wix, Squarespace, Webflow, and Elementor demos carried almost none.
- Lab data on a simulated mid-tier phone, one run each. Scores move from run to run.
- Only 4 of 58 pages had their own real-user data in Google's Chrome UX Report.
What slowed the pages
We read every audit Lighthouse flagged. The slow parts were different for each builder.
- Platform script. Wix demos carried a median 1,419 KB of script, mostly from Wix's own files, while images were small.
- Render-blocking files. Flagged on all pages for Squarespace, Elementor, Webflow, Unbounce, and ClickFunnels. Elementor had the biggest estimated savings, 2.3 to 7.8 seconds per page.
- Images and fonts. Elementor kit demos loaded a median 1,100 KB of images and 617 KB of fonts.
- Background video. Three of 7 Webflow templates loaded 7 MB or more, mostly media. Six of 7 ClickFunnels pages embedded a video player.
- Tracking tags. On Leadpages, GoHighLevel, and Unbounce pages, tags were most of the script and drove blocking time over Google's suggested 200 ms.
- Layout shift. Only GoHighLevel pages had a high median CLS, 0.338. Google rates over 0.25 as poor.
What this means for your ads
Google's own Quality Score help page says the speed your page loads can be the difference between someone bouncing or buying. So speed is worth checking. But our data does not say any one builder is the answer. It says the choices on the page, like video, image size, fonts, and tags, move the result a lot.
- Test the exact final URL from your ad, on mobile.
- Fix the slow parts first: big media, extra fonts, extra tags, images without sizes.
- Check that your Google Ads conversion tag still fires after every change. See conversion tracking not working.
- Test again a week later, since pages get slower after edits and new scripts.
The page you send clicks to can matter. In one ClickMend case, a flooring company's two pages scored 51 at 7.7 seconds and 100 at 1.8 seconds, and cost per lead went from $74 to $56 after the switch to the faster page. That is one advertiser, not a builder test, and results vary.

Frequently asked questions
Which landing page builder is fastest for Google Ads?
Our data can't settle that. Medians ranged from 32 to 75, but the ClickFunnels, Leadpages and GoHighLevel pages were the vendors' own marketing pages with the vendors' own tags, not template demos. The range inside each builder was wide too. Your own page can be fast or slow on any of them.
Why are the LCP numbers so high?
PageSpeed Insights runs lab tests on a simulated mid-tier phone over a slow mobile network. On the 4 pages that also had real-user data, real visitors saw the main content in 1.8 to 4.4 seconds, while the lab showed 5.6 to 21.9 seconds. Use lab numbers to compare and to find slow parts.
Should I switch builders to get a faster page?
Not first. In our data, many slow parts were choices on the page: background video, big images, heavy fonts, and tracking tags. Fix those, test again, and only then decide if the builder is the limit.
Can I see the raw data?
Yes. We recorded every page URL, the date, and the raw metrics for all 58 pages, including each failed Lighthouse audit. The method is in the How we tested section above.
