Ensure search engines can crawl, parse, and rank every page on your domain with our comprehensive 12-point technical audit checklist.
Even the most well-written articles and beautiful website designs cannot generate organic search traffic if search crawlers encounter technical roadblocks. Technical SEO is the practice of optimizing your website’s infrastructure so search engines like Google, Bing, and AI search engines can easily discover, crawl, and index your content.
This 12-point Technical SEO Checklist provides a step-by-step diagnostic framework used by Web Boosting Agency during every comprehensive SEO Audit.
Google requires secure HTTPS encryption. Verify that all HTTP traffic automatically redirects to HTTPS via 301 redirects and ensure zero mixed-content warnings exist on media files.
Review your robots.txt file to ensure critical CSS, JS, and conversion pages are not accidentally blocked. Direct crawlers to your primary XML sitemap location.
Ensure your XML sitemap includes only 200 OK status canonical URLs. Exclude non-canonical URLs, 404 broken pages, 301 redirects, and pages set to noindex.
Add self-referencing <link rel="canonical"> tags on every page to prevent duplicate content indexing caused by tracking parameters or pagination URLs.
Use Google PageSpeed Insights to measure LCP (<2.5s), INP (<200ms), and CLS (<0.1). Learn more in our Website Speed Optimization guide.
Embed structured data for Organization, WebSite, WebPage, Service, and Article schemas to qualify for Google rich search results.
Eliminate 404 dead links and multi-hop 301 redirect chains to preserve crawl budget and PageRank link equity.
Ensure all elements pass Google Mobile-Friendly tests with touch targets of at least 48px and zero horizontal scrolling on smartphones.
Perform internal link audits to verify that every published webpage has at least 2–3 contextual inbound internal links from higher-level category pages.
Convert legacy JPEG/PNG images to modern WebP formats, add explicit width and height attributes, and include descriptive alt text.
Add semantic BreadcrumbList schema and visible breadcrumb trails to reinforce URL hierarchy for users and crawlers.
Design a custom 404 page featuring a search bar, key service links, and a direct contact link to retain lost visitors.
