bestflag.com website review

19 images could be 2.1 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Your mobile performance score is 82. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Facebook, Shopify and Clarity and others), adding 905 KiB and 747 ms of main-thread time.

2 files block the first paint until they finish downloading. Deferring or inlining them could save about 500 ms.

About 289 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 150 ms faster on a phone.

18 files are served with short cache lifetimes, so returning visitors download them again (425 KiB).

A phone's processor spends 3.4 s on main-thread work while loading, 1.5 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 2,901 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

About 35 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

8 long tasks block the main thread while loading, the longest for 128 ms. During a long task the page ignores taps.

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.

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

2 KiB could be saved by minifying CSS.

The page becomes fully interactive after 18.8 s. Good is under 3.8 s.

Visually, the page fills in at 7.6 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 134 ms to 178 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your largest element takes 3.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Promote your brand. Celebrate milestones. Inspire people to…”.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 1.6 s to 1.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

15 images are downloaded at several times the size a phone draws them, for example instagram-post-customer-photo-flag-killedwithkidness-1.webp at 1,081 px wide, shown at 111 px. Resized copies would save about 7.9 MB.

4 images weigh 6.4 MB together. On a phone connection a single image that size takes seconds.

Your homepage downloads 5.0 MB in 251 requests on a phone: images 2.8 MB (58), scripts 1.0 MB (54) and other files 842 KiB (127). Under 2 MB keeps phones on slow connections fast.

7 images (7.3 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.

By the Sustainable Web Design model, a visit to your homepage emits about 1.41 g of CO₂e: 168.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

3 tap targets are too small or too close together to hit reliably with a finger.

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

All page content should be contained by landmarks: 8 elements on the page fail this check, rated moderate by axe-core.

16 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.

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

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

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

3 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

1 link has no real href, so search engines can't follow it.

The homepage links to 391 pages on bestflag.com and 10 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 /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.

We fetched 15 pages linked from your homepage (of 150 found) and read each the way a search engine does.

3 errors were logged to the browser console while the page loaded, for example “Uncaught Error: Minified React error #418; visit https://reactjs.org/docs/error-decoder.html?invariant=418 for the full…”.

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

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.

bestflag.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.

bestflag.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.

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

The homepage carries about 955 words of visible text.

DMARC is set to p=none, so mail pretending to be bestflag.com is still delivered. Add a report address, check the reports, then move to quarantine.

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, HubSpot and Meta Pixel and 1 more (measured from a US location before any click). A consent tool (HubSpot cookie banner) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 24 cookies, 6 of them by other companies (measured from a US location before any click).

Loading the homepage contacts 34 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
