How to Perform a Technical SEO Audit in 2026 (Step-by-Step Guide)

Step 1: Crawl your website — discover every page and error

The problem: You can't fix what you can't see. Most sites have hidden pages, broken links, and orphan content that never appear in analytics.

The solution: Run a full-site crawl using CrawlRaven, Screaming Frog, or Sitebulb. Enter your homepage URL and let the crawler follow all internal links. Google's crawler documentation confirms that Googlebot discovers pages by following links — so your crawler should mimic this behavior.

Key data to collect during the crawl:

• HTTP status codes (200, 301, 302, 404, 500)
• Title tags and meta descriptions
• H1 tags and header structure
• Canonical URLs and noindex tags
• Internal link structure and image alt text
• Page load time

Step 2: Check crawlability and indexation — unblock your important pages

The problem: Misconfigured robots.txt or noindex tags can silently block search engines from your most important pages. Google's robots.txt specification describes exactly how crawlers interpret these directives.

The solution: Systematically verify each access control:

• Validate your robots.txt — ensure it's not accidentally blocking important sections
• Check your XML sitemap — validate it's correct and submitted to Google Search Console
• Verify canonical tags — check for self-referencing canonicals and cross-domain issues
• Audit noindex tags — ensure they're only on pages you intentionally want to exclude

Step 3: Analyze on-page technical elements — fix the content signals

The problem: Duplicate title tags, missing meta descriptions, and broken header hierarchies dilute your content signals and confuse search engines.

The solution: For each crawled page, review against Google's title link guidelines:

• Title tags: unique, 50–60 characters, contains primary keyword
• Meta descriptions: unique, 120–160 characters, compelling copy
• H1 tags: one per page, contains primary keyword
• Content: original, matches search intent, minimum 300 words
• Images: compressed, with descriptive alt text per Google Images best practices

Step 4: Assess Core Web Vitals — fix performance before Google does it for you

The problem: Google uses Core Web Vitals as a ranking signal. Sites failing CWV thresholds lose visibility to faster competitors.

The solution: Check your CWV scores using Google Search Console or CrawlRaven's built-in performance analysis. Target these thresholds from web.dev:

• LCP (Largest Contentful Paint): Under 2.5 seconds
• CLS (Cumulative Layout Shift): Under 0.1
• INP (Interaction to Next Paint): Under 200ms

Step 5: Audit links — eliminate broken paths and orphan pages

The problem: Broken internal links waste crawl budget and create dead ends for users and search engines. Google's link best practices emphasize that internal links are a primary discovery mechanism.

The solution: Run a link audit to find:

• Broken internal links (returning 404 errors)
• Broken external links
• Redirect chains and loops
• Pages with no internal links (orphan pages)
• Excessive outbound links on single pages

Step 6: Validate structured data — claim your rich results

The problem: Invalid or missing structured data means you're leaving rich results (stars, FAQs, how-to carousels) on the table.

The solution: Use Google's Rich Results Test and CrawlRaven's schema checker to validate your JSON-LD, Microdata, and RDFa. Reference Schema.org for the latest vocabulary.

Step 7: Prioritize and create an action plan — fix high-impact issues first

The problem: A typical audit surfaces hundreds of issues. Without prioritization, teams waste time on low-impact fixes.

The solution: Sort all issues by impact and effort. Fix critical errors (broken pages, crawl blocks, Core Web Vitals failures) first. Then address high-impact on-page issues, followed by quick wins.

CrawlRaven automatically prioritizes all issues by estimated SEO impact, so you always know what to fix first.
