Technical SEO Audit
A Technical SEO Audit is a comprehensive evaluation of a website's technical infrastructure including crawlability, indexability, performance, mobile experience, and structured data implementation. It identifies issues that prevent search engines and AI systems from discovering, crawling, and indexing content effectively, prioritizing findings by impact and effort to fix.
Definition
A technical SEO audit examines crawlability (robots.txt, XML sitemaps, internal linking), indexability (canonical tags, robots meta tags, noindex), site structure (URL structure, information architecture), performance (page speed, Core Web Vitals), mobile experience, SSL/HTTPS, and structured data implementation. Audits typically use automated tools to scan the site and identify issues like broken links, duplicate content, orphaned pages, and crawl errors. Results are prioritized by impact and effort.
Conducting an audit involves using tools like Google Search Console, site crawlers, and performance monitors to gather data, analyzing results against SEO best practices, documenting findings with examples, and prioritizing fixes based on business impact. Follow-up audits after fixes verify that issues are resolved and new issues have not been introduced.
Why it matters for AI visibility
AI systems rely on the same technical infrastructure as search engines to discover and understand content. If your site has crawlability issues, duplicate content, missing structured data, or poor performance, AI systems will struggle to efficiently extract information. A well-executed technical foundation signals to AI systems that your site is professionally maintained and worth citing. Conversely, technical issues signal carelessness or low quality, reducing AI confidence in your content.

Crawling and Indexing
Crawling is the process of search engine and AI bots discovering web pages by following hyperlinks and sitemaps, while indexing is the process of storing, parsing, and analyzing page content so it can be retrieved and ranked in search results or cited in AI responses. Not all crawled content is indexed; pages may be excluded due to directives, quality signals, or duplication.
SEOCore Web Vitals
Core Web Vitals are three key user experience metrics that Google uses as ranking factors: Largest Contentful Paint (LCP, loading speed to 2.5 seconds), Interaction to Next Paint (INP, responsiveness under 200ms), and Cumulative Layout Shift (CLS, visual stability under 0.1). These metrics directly affect page rankings and are measured at the 75th percentile across real user data.
SEOSchema Markup
Schema Markup is structured data code added to web pages using standardized vocabularies (primarily Schema.org) that helps search engines and AI systems understand page content, meaning, context, and entity relationships. Implemented via JSON-LD, Microdata, or RDFa formats, schema markup enables rich snippets, knowledge panels, and enhanced search features while signaling content credibility and organization to automated systems.
SEOGoogle Search Console
Google Search Console is Google's official free platform for website owners to monitor a website's presence in search results, report crawl and indexation issues, submit sitemaps and URL changes, and analyze comprehensive search performance data including queries, impressions, and click metrics.
