Guide

An SEO site audit is a systematic evaluation of a web page or website to identify technical and on-page issues that affect search engine visibility. Think of it as a diagnostic checkup. You examine the HTML, evaluate how search engines will interpret the content, and produce a list of issues ranked by severity. This guide explains what a thorough site audit checks, why each factor matters, and how to fix common issues. The title tag is the single most important on-page SEO element. It appears in the browser tab, in search engine results as the clickable headline, and in social media shares. Google typically displays 50 to 60 characters of a title tag before truncating it. An effective title tag includes the primary keyword near the beginning, accurately describes the page content, and entices the searcher to click. Common issues include missing title tags, duplicate titles across multiple pages, titles that are too long or too short, and titles stuffed with keywords rather than written for humans. The meta description does not directly influence rankings, but it heavily influences click-through rate. Google displays approximately 150 to 160 characters of the meta description in search results. A well-written meta description acts as ad copy for your page. It should include the target keyword naturally, communicate the page's value proposition, and contain a call to action or clear reason to click. Missing meta descriptions force Google to auto-generate a snippet from page content, which rarely produces the best possible result. Heading hierarchy (H1 through H6) structures your content for both users and search engines. Every page should have exactly one H1 tag that clearly states the page topic and includes the primary keyword. H2 tags break the content into major sections. H3 tags create subsections within H2 sections. This hierarchy creates a logical outline that helps search engines understand content structure and helps users scan the page. Common issues include missing H1 tags, multiple H1 tags on one page, skipped heading levels (jumping from H1 to H3), and headings that do not describe their section content. Image optimization covers several factors. Every meaningful image should have descriptive alt text that explains what the image shows. Alt text serves three purposes: accessibility for screen readers, context for search engines that cannot see images, and display text when images fail to load. Alt text should be descriptive but concise, naturally incorporating keywords where relevant without stuffing. Beyond alt text, images should have appropriate file sizes (compressed for web), descriptive file names (blue-running-shoes.jpg rather than IMG_4532.jpg), and proper width and height attributes to prevent layout shift. Internal links connect pages within your site. They distribute page authority, help search engines discover and understand site structure, and guide users to related content. An audit checks whether pages have sufficient internal links, whether anchor text is descriptive (click here is bad, learn about protein powder is good), and whether important pages are linked from multiple locations. Orphan pages, pages with no internal links pointing to them, are particularly problematic because search engines may not discover them through crawling. External links point from your page to other websites. Linking to relevant, authoritative external sources adds credibility and context. An audit checks that external links work (no broken links), that they open in appropriate ways (new tab for external, same tab for internal), and that they use appropriate rel attributes. Links to untrusted or irrelevant sites can hurt your page quality signals. Canonical tags tell search engines which version of a page is the authoritative one. If the same content is accessible at multiple URLs (with and without www, with and without trailing slash, with URL parameters), the canonical tag prevents duplicate content issues by pointing all versions to a single preferred URL. Missing canonical tags on pages with URL variations is a common audit finding. The fix is adding a self-referencing canonical tag to every page and ensuring canonical tags on duplicate pages point to the preferred version. Open Graph and Twitter Card meta tags control how your page appears when shared on social media. An audit checks for the presence of og:title, og:description, og:image, og:url, and twitter:card tags. Missing these tags means social platforms generate previews automatically, often producing poor results with wrong images or truncated text. Well-crafted social meta tags increase the likelihood that shares generate clicks. Structured data (Schema.org markup) helps search engines understand the type and context of your content. An audit checks for the presence and validity of JSON-LD structured data. Common types include Article, Product, FAQ, HowTo, LocalBusiness, and BreadcrumbList. Valid structured data can generate rich results in Google, including FAQ dropdowns, star ratings, recipe cards, and how-to steps. Invalid structured data (missing required fields, wrong data types) produces errors in Google Search Console and fails to generate rich results. Page speed factors that are visible in HTML include render-blocking resources (CSS and JavaScript in the head that delay rendering), unoptimized images (missing lazy loading, oversized dimensions), excessive DOM size (too many HTML elements), and inline styles or scripts that could be externalized and cached. While a full page speed audit requires tools like Lighthouse or PageSpeed Insights, the HTML alone reveals several optimization opportunities. Mobile friendliness starts with the viewport meta tag. Pages without a properly configured viewport meta tag (<meta name="viewport" content="width=device-width, initial-scale=1">) will not render correctly on mobile devices. Since Google uses mobile-first indexing, a page that does not render properly on mobile will suffer in rankings across all devices. The audit checks for viewport configuration, text sizing, and touch-friendly element spacing. Language and localization tags matter for multilingual sites. The hreflang attribute tells search engines which language and region a page targets, preventing the wrong language version from appearing in search results. An audit of multilingual pages checks that hreflang tags are present, that they reference all language versions including a self-referencing tag, and that the values use correct language and region codes. Content quality indicators visible in HTML include word count (thin content under 300 words rarely ranks well for competitive queries), keyword usage (primary keyword in title, H1, first paragraph, and naturally throughout the content), content-to-HTML ratio (pages bloated with code relative to actual content), and the presence of multimedia elements (images, videos, tables) that enrich the content experience. Security indicators start with HTTPS. Pages served over HTTP rather than HTTPS receive a ranking penalty and display browser warnings that deter visitors. An audit notes any mixed content issues where an HTTPS page loads resources (images, scripts, stylesheets) over HTTP, which can trigger browser warnings and break the secure connection indicator. The WebRecast site audit tool parses HTML you paste directly into the browser. This client-side approach means no data leaves your machine, making it safe to audit pages that are behind login walls, in development environments, or on sensitive internal sites. The tool checks each factor listed above and assigns a pass, warning, or fail grade with specific recommendations. Prioritizing audit findings is essential. Not every issue has the same impact. A missing title tag on a key landing page is critical. A missing alt tag on a decorative icon is minor. Focus your fix efforts on issues affecting your most important pages first, then work down to lower-priority items. Critical items include missing or duplicate title tags, missing canonical tags causing duplicate content, broken internal links, and missing H1 tags. High priority items include meta description issues, image alt text, heading hierarchy problems, and missing structured data. Medium priority items include Open Graph tags, external link attributes, and minor content quality issues. Regular auditing catches issues before they accumulate. Run a quick audit on every new page before publishing. Perform a comprehensive site audit monthly or quarterly depending on your site size and publishing frequency. After major site changes (redesigns, CMS migrations, URL restructuring), run a full audit immediately. The cost of finding and fixing issues early is far lower than recovering from rankings lost due to undetected technical problems. Documenting audit results creates accountability and tracks progress. Export your findings, note the fix for each issue, assign responsibility if working with a team, and set deadlines. Re-audit after fixes are implemented to verify they resolved the issues. Over time, your audit history shows whether your site's technical SEO health is improving, stable, or declining.
