Every Feature Explained

What it checks: The HTML title tag that appears in search results and browser tabs.

Ideal: 50-60 characters, unique, includes primary keyword.

Why it matters: Title tags are one of the most important on-page SEO factors. Google uses them to understand your page content and displays them in search results. A well-optimized title can significantly improve click-through rates.

What it checks: The meta description tag that appears below your title in search results.

Ideal: 150-160 characters with a compelling call-to-action.

Why it matters: While not a direct ranking factor, meta descriptions influence click-through rates. A compelling description can mean the difference between a user clicking your result or a competitor's.

What it checks: Presence and count of H1 heading tags on the page.

Ideal: Exactly one H1 per page that matches your primary topic.

Why it matters: The H1 tag signals to search engines what your page is about. Multiple H1s can confuse search engines about your page's primary topic.

What it checks: The hierarchy of H1-H6 headings throughout your page.

Ideal: Logical hierarchy (H1 → H2 → H3) without skipping levels.

Why it matters: Proper heading structure helps search engines understand your content hierarchy and improves accessibility for screen readers.

What it checks: Whether all images have descriptive alt text.

Ideal: 100% of images should have relevant, descriptive alt text.

Why it matters: Alt text helps search engines understand image content, improves accessibility, and can drive traffic through image search.

What it checks: Total word count on the page.

Ideal: At least 300 words for basic pages, 1000+ for in-depth content.

Why it matters: Longer, comprehensive content tends to rank better as it provides more value to users. However, quality matters more than quantity.

What it checks: Presence of a canonical URL tag.

Ideal: Every page should have a self-referencing canonical tag.

Why it matters: Canonical tags prevent duplicate content issues by telling search engines which version of a page is the "master" copy.

What it checks: The lang attribute on the HTML tag.

Ideal: Should be set (e.g., lang="en" for English).

Why it matters: Helps search engines understand the language of your content and serve it to the right audience.

What it checks: Number of links pointing to other pages on your website.

Ideal: 5+ internal links per page to relevant content.

Why it matters: Internal links help search engines discover your content and distribute page authority throughout your site.

What it checks: Links that lead to 404 errors or non-existent pages.

Ideal: Zero broken links on your website.

Why it matters: Broken links create poor user experience and waste crawl budget. They signal to search engines that your site may be poorly maintained.

What it checks: Presence of navigation menu with proper link structure.

Ideal: Clear nav element with links to important pages.

Why it matters: Good navigation helps users and search engines find your important content. It also distributes page authority to key pages.

What it checks: Time until the largest content element is visible.

Ideal: Under 2.5 seconds for good score.

Why it matters: LCP is a Core Web Vital and direct Google ranking factor. It measures perceived load speed - how quickly users see meaningful content.

What it checks: How much the page layout shifts during loading.

Ideal: Score under 0.1 for good user experience.

Why it matters: Layout shifts are frustrating when you're about to click something and it moves. CLS is a Core Web Vital and ranking factor.

What it checks: Time the main thread is blocked and can't respond to user input.

Ideal: Under 200ms for good interactivity.

Why it matters: High TBT means users can't interact with your page even though it looks loaded. This creates frustration and increases bounce rates.

What it checks: Time until the first content element renders.

Ideal: Under 1.8 seconds for good score.

Why it matters: FCP tells users something is happening. A slow FCP makes users think your site is broken or unresponsive.

What it checks: Total size of HTML, CSS, JS, and images.

Ideal: Under 3MB for optimal performance.

Why it matters: Large pages take longer to download, especially on mobile. This directly impacts load time and user experience.

What it checks: Whether your site uses HTTPS encryption.

Ideal: All pages must use HTTPS.

Why it matters: HTTPS is a confirmed Google ranking factor. Browsers also show "Not Secure" warnings for HTTP sites, which destroys user trust.

What it checks: HTTP Strict Transport Security header.

Ideal: Enabled with max-age of at least 1 year.

Why it matters: HSTS forces browsers to only connect via HTTPS, preventing man-in-the-middle attacks and protocol downgrade attacks.

What it checks: Content-Security-Policy header configuration.

Ideal: Configured to restrict script and content sources.

Why it matters: CSP prevents XSS attacks by controlling what resources can be loaded on your page. Essential for protecting your users.

What it checks: X-Frame-Options header to prevent clickjacking.

Ideal: Set to DENY or SAMEORIGIN.

Why it matters: Prevents attackers from embedding your site in an iframe to trick users into clicking hidden elements (clickjacking).

What it checks: Viewport meta tag configuration.

Ideal: viewport meta tag with width=device-width.

Why it matters: Without proper viewport settings, your site won't display correctly on mobile devices. Google uses mobile-first indexing.

What it checks: Presence and validity of robots.txt file.

Ideal: Valid robots.txt with sitemap reference.

Why it matters: Robots.txt tells search engines what to crawl. A missing or misconfigured file can block important pages from being indexed.

What it checks: Presence of XML sitemap.

Ideal: Valid sitemap at /sitemap.xml with all important pages.

Why it matters: Sitemaps help search engines discover and crawl all your pages efficiently, especially for larger sites.

What it checks: og:title, og:description, og:image meta tags.

Ideal: All three tags present with optimized content.

Why it matters: Open Graph controls how your content appears when shared on Facebook, LinkedIn, and other platforms. Good OG tags increase click-through rates from social.

What it checks: Structured data in JSON-LD or Microdata format.

Ideal: Relevant schema types (LocalBusiness, Organization, etc.).

Why it matters: Schema markup helps search engines understand your content and can enable rich snippets in search results (stars, prices, FAQs).

What it checks: Readability score based on sentence and word complexity.

Ideal: Score of 60-70 for general web content.

Why it matters: Content that's easy to read keeps visitors on your page longer. Complex content has higher bounce rates.

What it checks: Frequency of top keywords in your content.

Ideal: Primary keyword at 1-3% density.

Why it matters: Too low means search engines may not understand your topic. Too high (keyword stuffing) can trigger penalties.
