davedowning.com website review

25 files are served with short cache lifetimes, so returning visitors download them again (2.4 MB).

11 images could be 1.8 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Your mobile performance score is 87. Pages that score under 90 lose visitors before the first paint.

8 files block the first paint until they finish downloading. Deferring or inlining them could save about 750 ms.

About 52 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

FontAwesome CDN costs a phone 6 ms of main-thread work and 373 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.

5 third-party services load with your homepage (cloudflare.com, JSDelivr CDN and FontAwesome CDN and others), adding 454 KiB and 47 ms of main-thread time.

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

8 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.

The first text or image appears after 2.9 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 5.1 s (Speed Index). Good is under 3.4 s.

Your largest element takes 2.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Downing Filtration is a family of companies located in Phoe…”. Most of its time is element render delay (2.5 s).

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

Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

Your homepage downloads 4.5 MB in 40 requests on a phone: images 2.3 MB (14), other files 1.5 MB (4) and fonts 344 KiB (3). Under 2 MB keeps phones on slow connections fast.

6 images are downloaded at several times the size a phone draws them, for example LEED.jpeg at 2,310 px wide, shown at 237 px. Resized copies would save about 1.1 MB.

10 images (1.9 MB) 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.

7 images further down the page (1.2 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 1.28 g of CO₂e: 153.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

All page content should be contained by landmarks: 16 elements on the page fail this check, rated moderate by axe-core.

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

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

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

Headings skip levels (h1 → h4), which makes the page harder to scan with a screen reader.

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

Your title is only 18 characters: “Downing Filtration”. Between 30 and 65 characters leaves room to say what you do and for whom.

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

There are 23 <h1> headlines (“ABOUT US”, “LOCATIONS” and “LOCATIONS”). One clear main headline is easier for people and search engines.

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

No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

No XML sitemap at https://downingfiltration.com/sitemap.xml, so Google discovers your pages only by following links.

There is no robots.txt at downingfiltration.com/robots.txt, the first file search crawlers ask for.

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

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 35 pages on davedowning.com and 7 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://downingfiltration.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://downingfiltration.com/merv, https://downingfiltration.com/company, https://downingfiltration.com/resources, https://downingfiltration.com/products and https://downingfiltration.com/prefilter and 5 others all use the title “Downing Filtration”. Search engines can't tell which page to show for a search, so each competes with the others.

https://downingfiltration.com/merv, https://downingfiltration.com/company, https://downingfiltration.com/resources, https://downingfiltration.com/products, https://downingfiltration.com/prefilter and https://downingfiltration.com/finalfilter and 4 others have no meta description, so Google writes the search snippet from whatever text it finds.

https://downingfiltration.com/hega, https://downingfiltration.com/hepa and https://downingfiltration.com/belts have no <h1> headline, so visitors and search engines get no clear main topic.

https://downingfiltration.com/hega and https://downingfiltration.com/hepa 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 10 pages linked from your homepage and read each the way a search engine does.

6 of 7 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

2 errors were logged to the browser console while the page loaded, for example “%c%d font-size:0;color:transparent NaN”.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

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

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.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

The homepage has only about 182 words of visible text; thin pages give Google and first-time buyers little to go on.

The homepage shows no opening hours. If customers visit or call, show when.

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

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