serpninja.io website review

22 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.1 s.

Your mobile performance score is 84. Pages that score under 90 lose visitors before the first paint.

About 85 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.

1 third-party service load with your homepage (Google Fonts), adding 166 KiB and 3 ms of main-thread time.

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 4.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Play Video”. Most of its time is element render delay (1.9 s).

Real visitors wait 2.7 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors wait 271 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Real visitors see the first content after 2.7 s (75th percentile). Good is under 1.8 s.

Real visitors wait 1.8 s for your server to start answering (75th percentile). Good is under 800 ms.

Visually, the page fills in at 4.1 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 4.1 s. Good is under 3.8 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 235 ms to 260 ms 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 0.16 g of CO₂e: 19.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 element hidden from screen readers can still receive keyboard focus.

Interactive controls must not be nested: 1 element on the page fails this check, rated serious by axe-core.

All page content should be contained by landmarks: 78 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.

The skip-link target should exist and be focusable: 1 element on the page fails this check, rated moderate by axe-core.

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

Your meta description is only 68 characters: “Unrivaled Link Building Expertise. Zeroing in on What Truly Matters.”. 70 to 160 characters is enough to sell the click.

Structured data found (ImageObject, Organization, PostalAddress and VideoObject) but with 1 problem, for example “VideoObject: hasPart is an empty list”.

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

The homepage links to 87 pages on serpninja.io and 5 external pages.

Your Organization JSON-LD is missing url, sameAs (social profiles), description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

There is no https://serpninja.io/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://serpninja.io/guest-post-service, https://serpninja.io/pbn-rentals, https://serpninja.io/google-my-business-verification and https://serpninja.io/casino-gambling-seo use the same meta description. A description written for each page earns more clicks.

https://serpninja.io/listicle-backlinks has no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 36 found) and read each the way a search engine does.

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.

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

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

The homepage carries about 619 words of visible text.

Opening the homepage sets 1 cookie (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 2 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
