tdconversions.com website review

About 250 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.4 s faster on a phone.

11 files are served with short cache lifetimes, so returning visitors download them again (238 KiB).

Your mobile performance score is 63. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Google Tag Manager, OptiMonk and enzuzo.com and others), adding 655 KiB and 563 ms of main-thread time.

Polyfills for old browsers add 49 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 450 ms faster on a phone.

A phone's processor spends 2.4 s on main-thread work while loading, 1.1 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

6 long tasks block the main thread while loading, the longest for 228 ms. During a long task the page ignores taps.

2 images could be 50 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 150 ms faster on a phone.

17 KiB JavaScript is shipped twice across bundles. Google estimates it would make the page about 150 ms faster on a phone.

5 files block the first paint until they finish downloading. Deferring or inlining them could save about 50 ms.

About 13 KiB of CSS is downloaded but never applied on this page.

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.

Your largest element takes 11.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “1 Make 2 Engine 3 Conversion Type SEARCH RESET”.

The page becomes fully interactive after 11.8 s. Good is under 3.8 s.

Visually, the page fills in at 6.2 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 253 ms in total while the page loads. Good is under 200 ms.

The first text or image appears after 1.9 s on a phone. Good is under 1.8 s.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 70 ms to 64 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 1.4 s to 1.3 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

By the Sustainable Web Design model, a visit to your homepage emits about 0.51 g of CO₂e: 60.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

15 buttons have no accessible name, so screen readers announce just “button”.

6 text elements don'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.

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

Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.

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

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

There is no <h1>, so neither visitors nor Google get a clear main headline.

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

3 links have no real href, so search engines can't follow them.

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

The homepage links to 176 pages on tdconversions.com and 1 external page.

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.

/customer_authentication/redirect has no <title>, so Google invents the link text in results.

/customer_authentication/redirect is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

/customer_authentication/redirect has no meta description, so Google writes the search snippet from whatever text it finds.

/collections/volkswagen-kits, /collections/bmw-m57-kits, /collections/volkswage-3-0l-v6-tdi-adapter-kits, /collections/gasoline-engine-adapter-kits, /collections/volkswagen-gasoline-engine-adapter-kits and /collections/engine-mounts and 2 others use the same meta description. A description written for each page earns more clicks.

/customer_authentication/redirect, /pages/install-guides and /apps/trackingmore have no <h1> headline, so visitors and search engines get no clear main topic.

/pages/install-guides, /apps/trackingmore and /collections have under 150 words in the HTML. Thin pages rarely rank; if the text loads with JavaScript, crawlers that don't run it see even less.

We fetched 15 pages linked from your homepage (of 41 found) and read each the way a search engine does.

On a 390 px-wide phone the page scrolls sideways, a sign that something is wider than the screen.

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

HSTS is set, but max-age is 91 days; one year is the recommended minimum.

2 links go through two or more redirects, for example https://tdconversions.com/customer_authentication/redirect?locale=en&region_country=US.

No Referrer-Policy header, so full URLs can leak to the sites you link to.

No Permissions-Policy header to switch off camera, microphone and location for embedded content.

X-XSS-Protection is set to “1; mode=block”; the header is deprecated and can introduce bugs. Use 0 or remove it.

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

tdconversions.com is registered until Jan 2027. Make sure auto-renew is on and the card on file is current.

tdconversions.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.

tdconversions.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.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

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 343 words of visible text.

tdconversions.com has no DMARC record, so nothing tells receivers what to do with mail that fails SPF or DKIM. Gmail and Yahoo require DMARC from bulk senders.

We found no DKIM key on the selectors the big email providers use. If you send through one of them, turning on DKIM signing improves delivery.

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 and Google Tag Manager (measured from a US location before any click). No consent tool was detected. Visitors from the EU, UK and several US states must be asked first.

Opening the homepage sets 14 cookies (measured from a US location before any click).

No known cookie consent tool loads with the page. Some sites build their own banner, and some only show one to visitors from the EU.

Loading the homepage contacts 23 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
