symprove.com website review

5 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.1 s.

Your mobile performance score is 49. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 6.3 s on main-thread work while loading, 3.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google Tag Manager, Clarity and Shopify and others), adding 3.9 MB and 1.8 s of main-thread time.

Google Tag Manager costs a phone 951 ms of main-thread work and 738 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

About 673 KiB of JavaScript is downloaded but never used on this page.

36 files are served with short cache lifetimes, so returning visitors download them again (370 KiB).

About 117 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 450 ms faster on a phone.

13 long tasks block the main thread while loading, the longest for 414 ms. During a long task the page ignores taps.

Shopify costs a phone 142 ms of main-thread work and 2.5 MB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

3 images could be 54 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 100 ms faster on a phone.

Polyfills for old browsers add 67 KiB JavaScript that modern phones do not need.

11 KiB could be saved by minifying JavaScript.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

The page becomes fully interactive after 23.9 s. Good is under 3.8 s.

Scripts block taps and scrolling for 1.3 s in total while the page loads. Good is under 200 ms.

Your largest element takes 5.4 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

Visually, the page fills in at 7.0 s (Speed Index). Good is under 3.4 s.

12 images have no width and height attributes, so the layout jumps as each one loads.

Your homepage downloads 5.9 MB in 351 requests on a phone: media 2.1 MB (1), scripts 2.1 MB (105) and other files 1.0 MB (195). Under 2 MB keeps phones on slow connections fast.

1 image is downloaded at several times the size a phone draws it, for example Droplet_Image_bc20acbc-8739-4f29-9787-4fbcc668241c.webp at 360 px wide, shown at 80 px. Resized copies would save about 155 KiB.

2 images (336 KiB) are JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

By the Sustainable Web Design model, a visit to your homepage emits about 1.67 g of CO₂e: 199.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Scrollable region must have keyboard access: 2 elements on the page fail this check, rated serious by axe-core.

1 image has no alt text, which hurts accessibility and image search.

All page content should be contained by landmarks: 2 elements on the page fail this check, rated moderate by axe-core.

Users should be able to zoom and scale the text up to 500%: 1 element on the page fails this check, rated minor by axe-core.

Headings skip levels (h2 → h4), which makes the page harder to scan with a screen reader.

Elements with visible text labels do not have matching accessible names. (1 element).

There are 2 <h1> headlines (“Symprove UK” and “94% feel the difference†”). One clear main headline is easier for people and search engines.

Your meta description is 173 characters; Google truncates after about 160, so the end of your pitch is cut.

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

The homepage links to 77 pages on symprove.com and 7 external pages.

https://www.symprove.com/products/symprove-on-the-go, https://www.symprove.com/pages/help and https://www.symprove.com/pages/help-centre are marked noindex but linked from your homepage. If they are meant to be found, remove the noindex.

https://www.symprove.com/pages/help and https://www.symprove.com/pages/help-centre all use the title “Help Centre & Frequently Asked Questions | Symprove UK”. Search engines can't tell which page to show for a search, so each competes with the others.

https://www.symprove.com/products/symprove-on-the-go, https://www.symprove.com/pages/symprove-science, https://www.symprove.com/pages/why-it-works and https://www.symprove.com/pages/quality-standards have no meta description, so Google writes the search snippet from whatever text it finds.

https://www.symprove.com/pages/help and https://www.symprove.com/pages/help-centre use the same meta description. A description written for each page earns more clicks.

Your homepage links to 1 page by a URL that isn't its canonical one, for example https://www.symprove.com/products/symprove, whose canonical is https://www.symprove.com/products/symprove?view=default. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

https://www.symprove.com/products/symprove, https://www.symprove.com/pages/ingredients, https://www.symprove.com/pages/why-it-works, https://www.symprove.com/blogs/the-gut-hub, https://www.symprove.com/pages/about and https://www.symprove.com/blogs/gut-health-guides and 3 others have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 26 found) and read each the way a search engine does.

1 image failed to load on a phone, for example https://sp.analytics.yahoo.com/sp.pl?a=10000&d=Thu%2C%2005%20Nov%202026%2007%3A49%3A11%20GMT&n=0&b=Symprove%20Probiotic%20Supplement%20-%20Lowest%20Price%20Guarantee&.yp=10202919&f=https%3A%2F%2Fwww.s.

4 of 15 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

5 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

2 images are displayed at the wrong aspect ratio, so they look stretched or squashed.

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

The homepage carries about 1,095 words of visible text.

Before a visitor clicks anything, the page loads Amazon Ads, Google Ads, Google Analytics, Google Tag Manager and Klaviyo and 7 mores (measured from a US location before any click). A consent tool (OneTrust) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 31 cookies, 1 of them by other companies (measured from a US location before any click).

Loading the homepage contacts 62 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
