Keyword & Content Depth Analysis

Understand exactly how search engines read your page copy

Thin, poorly structured content is one of the most common reasons websites underperform in organic search. Our free SEO content analyser goes further than a simple word count:

  • Visible body word count measured after scripts and stylesheets are stripped from the DOM
  • Flesch–Kincaid readability score computed to gauge how accessible your writing is (pass ≥ 55)
  • Top-40 keyword frequency map extracted directly from live body text — ordered from most to least dominant
  • Single-word, two-word, and three-word phrase density tables with percentage breakdown
  • Cross-reference of your top 8 keywords against meta title, meta description, and all headings
  • Text-to-HTML ratio alert when inline markup dominates over meaningful visible content

Website SEO Problems We Find and Fix

These are the most damaging on-site SEO errors affecting real websites today. Every single one is automatically detected during your free unlimited website scan.

On-Page▲ High

Meta title absent or outside optimal length

A title shorter than 10 or longer than 60 characters loses keyword focus, reduces search snippet quality, and lowers expected click-through rate.

Performance▲ High

Server response time (TTFB) above 800 ms

Slow first-byte delivery delays page rendering, degrades Core Web Vitals scores, and signals poor hosting infrastructure to ranking algorithms.

Security▲ High

Website not secured with HTTPS

Pages loaded over plain HTTP are flagged as unsafe by every major browser, receive weaker trust signals, and rank below HTTPS-secured equivalents.

Content▲ High

Page word count below 300 words

Thin pages lack the content depth search engines need to establish topical relevance, reducing their ability to rank for competitive queries.

Advanced▲ High

Structured data (JSON-LD) not implemented

Without Schema.org markup, your site cannot qualify for rich results including FAQ panels, article bylines, product ratings, or breadcrumb trails in SERPs.

Advanced▲ High

robots.txt file missing or returning an error

A missing robots.txt leaves crawlers without guidance, causing wasted crawl budget, accidental indexing of private pages, or missed content discovery.

On-Page● Medium

H1 heading absent or used more than once

A page with no H1 gives crawlers no primary topic signal. Multiple H1 tags create structural ambiguity that weakens topical authority in search results.

Social● Medium

Open Graph image and Twitter Card image absent

Without social preview images, links shared on Facebook, X (Twitter), and LinkedIn render as plain text — dramatically reducing engagement and clicks.

HTML● Medium

Character encoding (charset) not declared

An absent charset meta tag risks text-rendering inconsistencies across browsers and indicates an incomplete or poorly formed HTML document structure.

Mobile● Medium

Images lacking descriptive alt attributes

Alt text is read by screen readers for accessibility and by crawlers for image SEO. Three or more images without alt text triggers a failed audit result.

Performance▼ Low

DOM element count exceeds 1,500 nodes

A heavily nested DOM raises style recalculation time, increases Total Blocking Time, and degrades interaction responsiveness on lower-end devices.

Security▼ Low

External links open in new tab without rel security

Using target=_blank without rel="noopener noreferrer" exposes your page to reverse tabnapping — a vulnerability that can transfer window control to the opened tab.

All issues above — plus 28+ additional checks — run automatically in your free unlimited on-site SEO report. No login. No limits.
