sep.ir website review

4 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.2 s.

6 images could be 189 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 1.1 s faster on a phone.

Your mobile performance score is 52. Pages that score under 90 lose visitors before the first paint.

About 123 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 450 ms faster on a phone.

About 92 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.

3 third-party services load with your homepage (Google Tag Manager, Clarity and Google Analytics), adding 205 KiB and 164 ms of main-thread time.

4 long tasks block the main thread while loading, the longest for 65 ms. During a long task the page ignores taps.

1 file is served with short cache lifetimes, so returning visitors download them again (10 KiB).

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.

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 7.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “نیلسون ریپورت”.

Visually, the page fills in at 9.5 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 8.2 s. Good is under 3.8 s.

The layout shifts by 0.254 while loading, so content jumps under the reader's thumb. Good is under 0.1.

Real visitors wait 2.9 s for the largest content to appear (75th percentile). Good is under 2.5 s.

For real visitors the layout shifts by 0.21 (75th percentile). Good is under 0.1.

Real visitors see the first content after 2.4 s (75th percentile). Good is under 1.8 s.

Real visitors wait 1.2 s for your server to start answering (75th percentile). Good is under 800 ms.

The first text or image appears after 2.3 s on a phone. Good is under 1.8 s.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 112 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 2.8 s to 2.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

4 images (275 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.

4 images further down the page (275 KiB) 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 0.56 g of CO₂e: 67.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 dropdown has no label.

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

10 elements hidden from screen readers can still receive keyboard focus.

Some list items are not inside a list.

Some lists contain elements other than list items, which screen readers announce wrongly.

All page content should be contained by landmarks: 23 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.

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

3 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).

Your meta description is 176 characters; Google truncates after about 160, so the end of your pitch is cut.

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

No twitter:card tag. X falls back to Open Graph, which is set, so this is minor.

The homepage links to 97 pages on sep.ir and 31 external pages.

There is no https://www.sep.ir/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.

Your homepage links to 13 pages by a URL that isn't their canonical one, for example https://www.sep.ir/%D8%AF%D8%B1%D8%A8%D8%A7%D8%B1%D9%87-%D8%B3%D9%BE, whose canonical is https://www.sep.ir/%d8%af%d8%b1%d8%a8%d8%a7%d8%b1%d9%87-%d8%b3%d9%be. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

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 64 found) and read each the way a search engine does.

1 image failed to load on a phone, for example https://Trustseal.eNamad.ir/logo.aspx?id=47841&Code=VpgAEzCKiE79zD030CNt.

3 errors were logged to the browser console while the page loaded, for example “Loading the image 'https://trustseal.enamad.ir/logo.aspx?id=47841&Code=VpgAEzCKiE79zD030CNt' violates the following Con…”.

1 image is served at too low a resolution for sharp phone screens.

Chrome logged issues while loading the page (“Content security policy”).

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.

Social proof on the homepage: 3 trust badges. Pairing it with named testimonials or customer logos makes it far more convincing.

The homepage has only about 17 words of visible text; thin pages give Google and first-time buyers little to go on.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

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

Before a visitor clicks anything, the page loads Google Analytics, Google Tag Manager and Microsoft Clarity (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 6 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 4 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
