Content SEO is what you write. Technical SEO is how search engines and LLMs read it. Crawling, indexing, semantic markup, schema, Core Web Vitals, URL structure — the infrastructure layer that operates before content. Quote, audit, vendor selection, and technical debt resolution — all curated in one place.
Three core Technical SEO terms
The technical foundation that search engines and LLMs use to read a site. Crawling, indexing, semantic markup, schema, Core Web Vitals, page speed, URL structure, sitemap, robots.txt — the infrastructure layer that operates before content does.
Google's three core user experience metrics — LCP (Largest Contentful Paint), CLS (Cumulative Layout Shift), INP (Interaction to Next Paint). *Measurable signals* that directly affect ranking decisions.
The volume of crawling resources search engines and LLM crawlers allocate to a specific site. When wasted on crawl errors, duplicate URLs, or infinite redirects, core pages fail to index.
Quote · audit · crawl errors · vendor selection · Google standards — useful flow for both decision-makers and practitioners. Original articles are in Korean.

READ MORE (KR)Content SEO is what you write. Technical SEO is how search engines and LLMs read it. Crawling, indexing, semantic markup, schema, Core Web Vitals, URL structure — the infrastructure layer that operates before content. Even great content is invisible if the technical foundation is broken.
Baseline audit once at launch. Quarterly checks thereafter. Plus immediate audit when (1) URL structure changes, (2) large content additions, or (3) search traffic drops sharply. LogAgency's free diagnosis covers Core Web Vitals, crawl errors, and schema application state in one pass.
Google publicly stated Core Web Vitals are a ranking signal (2021). Not the sole decision factor, but a differentiating signal between content of equal quality. Recommended mobile thresholds: LCP under 2.5s, CLS under 0.1, INP under 200ms.
Google states schema is not a direct ranking factor. However, it contributes to (1) rich result eligibility, (2) Knowledge Graph entity connection, (3) AI search citation candidate signals. From a GEO perspective, schema is near-essential infrastructure. See also the Schema Markup topic.
(1) In-house build capability — direct markup and schema writing, not dependence on solutions or plugins. (2) Measurable metrics — concrete numbers like LCP, CLS, indexing rate, crawl error count, not vague "ranking improvement" promises. (3) Reproducible verification — actual cases showing citation or search results on live sites.
