tddctx.com website review

16 files block the first paint until they finish downloading. Deferring or inlining them could save about 6.3 s.

About 649 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 3.3 s faster on a phone.

Your mobile performance score is 48 (desktop: 70). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

8 third-party services load with your homepage (Mapbox, Google Tag Manager and osano.com and others), adding 993 KiB and 599 ms of main-thread time.

4 files are served with short cache lifetimes, so returning visitors download them again (171 KiB).

24 KiB could be saved by minifying JavaScript.

6 long tasks block the main thread while loading, the longest for 299 ms. During a long task the page ignores taps.

Mapbox costs a phone 187 ms of main-thread work and 467 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.

Polyfills for old browsers add 13 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

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.

Your largest element takes 12.4 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “The Leading GI Practice in Texas Providing digestive care a…”.

The first text or image appears after 7.5 s on a phone. Good is under 1.8 s.

The page becomes fully interactive after 13.1 s. Good is under 3.8 s.

Visually, the page fills in at 7.5 s (Speed Index). Good is under 3.4 s.

For real visitors the layout shifts by 0.15 (75th percentile). Good is under 0.1.

Scripts block taps and scrolling for 412 ms in total while the page loads. Good is under 200 ms.

1 image 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 104 ms to 111 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 1.8 s to 2.1 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

1 image (71 KiB) is 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 0.52 g of CO₂e: 63.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

3 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

4 visible links have no text or label, so screen readers cannot say where they go.

No meta description, so Google writes its own snippet from whatever text it finds.

No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.

1 link use generic text like “click here” or “learn more”, which tells Google nothing about the page behind it.

Open Graph is missing og:description, so shared links fall back to guesses.

The homepage links to 235 pages on tddctx.com and 11 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.

There is no https://tddctx.com/llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.

https://tddctx.com/reviews, https://tddctx.com/locations, https://tddctx.com/colonoscopy-patient-instructions, https://tddctx.com/contact-us, https://tddctx.com/about-us and https://tddctx.com/gastroenterologist-near-me and 9 others have no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 15 pages linked from your homepage (of 48 found) and read each the way a search engine does.

23 of 30 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 404 ()”.

Social proof on the homepage: a star rating. Pairing it with named testimonials or customer logos makes it far more convincing.

There is no form on the homepage, so every lead has to click through to another page first.

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 312 words of visible text.

Before a visitor clicks anything, the page loads Google Tag Manager (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 2 cookies (measured from a US location before any click).

Loading the homepage contacts 11 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
