certapro.com website review

Google Tag Manager costs a phone 3.2 s of main-thread work and 2.8 MB of downloads while your page loads. That alone is enough to make taps feel slow. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

12 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.9 s.

A phone's processor spends 9.3 s on main-thread work while loading, 6.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google Tag Manager, pure.cloud and Google CDN and others), adding 5.5 MB and 5.1 s of main-thread time.

About 2.6 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 90 ms faster on a phone.

54 files are served with short cache lifetimes, so returning visitors download them again (1.8 MB).

Your mobile performance score is 57. Pages that score under 90 lose visitors before the first paint.

pure.cloud costs a phone 819 ms of main-thread work and 1.1 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.

About 122 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.

Google CDN costs a phone 366 ms of main-thread work and 734 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.

20 long tasks block the main thread while loading, the longest for 391 ms. During a long task the page ignores taps.

16 images could be 345 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

osano.com costs a phone 269 ms of main-thread work and 84 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.

The page has 1,599 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Google Maps costs a phone 95 ms of main-thread work and 328 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.

23 KiB could be saved by minifying CSS.

87 KiB could be saved by minifying JavaScript.

Polyfills for old browsers add 26 KiB JavaScript that modern phones do not need.

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

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

The page becomes fully interactive after 48.3 s. Good is under 3.8 s.

Scripts block taps and scrolling for 2.9 s in total while the page loads. Good is under 200 ms.

Real visitors wait 444 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

The first text or image appears after 2.6 s on a phone. Good is under 1.8 s.

Your largest element takes 3.4 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

Visually, the page fills in at 3.9 s (Speed Index). Good is under 3.4 s.

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

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 238 ms to 246 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 2.7 s to 2.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 8.1 MB in 319 requests on a phone: scripts 6.0 MB (102), images 1.4 MB (92) and other files 418 KiB (89). Under 2 MB keeps phones on slow connections fast.

15 images (1,013 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.

17 images further down the page (1.0 MB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 2.30 g of CO₂e: 276.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

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

All page content should be contained by landmarks: 11 elements on the page fail this check, rated moderate by axe-core.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 2 elements on the page fail this check, rated moderate by axe-core.

Document should not have more than one banner landmark: 1 element on the page fails this check, rated moderate by axe-core.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

The viewport tag blocks pinch-zoom, which low-vision visitors rely on.

Alternative text of images should not be repeated as text: 14 elements on the page fail this check, rated minor by axe-core.

2 form fields have no label, so screen readers announce an empty box and autofill guesses.

The homepage links to 102 pages on certapro.com and 6 external pages.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

/residential-painting and /residential-painting/services all use the title “House Painters Near You | Interior & Exterior Painting”. Search engines can't tell which page to show for a search, so each competes with the others.

/paint-it-pink has no meta description, so Google writes the search snippet from whatever text it finds.

/residential-painting and /residential-painting/services use the same meta description. A description written for each page earns more clicks.

Your homepage links to 3 pages by a URL that isn't their canonical one, for example /residential-painting/services, whose canonical is /residential-painting. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

/blog has no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 59 found) and read each the way a search engine does.

3 images failed to load on a phone, for example https://bat.bing.com/action/0?ti=148021596&tm=gtm002&Ver=2&mid=4cd15b0c-fbab-4a57-bf34-cde2c40ab8db&bo=1&sid=e01990e0d2f411f197742392f6e80946&vid=e01a5c60d2f411f1bbb17f4fe03ca942&vids=0&msclkid=N&pi=9.

4 of 20 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 third-party cookie is set on load; browsers are restricting these, so whatever relies on them breaks.

5 errors were logged to the browser console while the page loaded, for example “Bootstrap's JavaScript requires jQuery version 1.9.1 or higher, but lower than version 3”.

Chrome logged issues while loading the page (“Cookie”).

1 link go through two or more redirects, for example https://facebook.com/certapropainters.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

certapro.com has no CAA record, so any certificate authority may issue a certificate for it. A CAA record naming your provider (for example letsencrypt.org) closes that door.

certapro.com's DNS answers are not signed. DNSSEC stops attackers forging them to send visitors or email elsewhere; most registrars switch it on in a click, though most sites still run without it.

Your longest form asks for 57 fields (0 required). Every extra field lowers completion.

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 1,007 words of visible text.

Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Meta Pixel and Microsoft Ads and 3 mores (measured from a US location before any click). A consent tool (Osano) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 18 cookies (measured from a US location before any click).

Loading the homepage contacts 45 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
