The technical readiness level of a website to be interpreted by AI engines, generative crawlers and RAG systems. It helps models find useful information and use it with less ambiguity.

Alt text explains what an image contributes when it cannot be seen or when assistive technology interprets it. It prevents a useful image from becoming lost information.

The title tag is the HTML title shown in search results and browser tabs. It is one of the main signals for understanding the topic of a page.

Indexability is the real ability of a page to be included in an index. It is not enough for the page to exist: it must be accessible, crawlable, coherent and not blocked by opposing signals.

A situation where robots.txt, meta robots, headers or technical errors prevent bots from accessing content. It helps confirm whether important pages can be discovered without obstacles or contradictory signals.

The approximate amount of resources a bot spends exploring a site before leaving or prioritizing other URLs. It helps confirm whether important pages can be discovered without obstacles or contradictory signals.

Navigation breadcrumbs that explain the hierarchical position of a URL within the site architecture. It helps people, search engines and AI models understand the real meaning of the page.

Schema.org is a standard vocabulary for describing elements such as organizations, articles, products, events or FAQs. It is like placing understandable labels on important parts of the website.

A semantic chunk is a content block that makes sense on its own. It can be read, extracted or reused without depending on everything around it.

The organization of content so that entities, topics and relationships are clear for humans and machines. It helps people, search engines and AI models understand the real meaning of the page.

An approach that structures content and entities so machines can understand relationships and meaning. It helps people, search engines and AI models understand the real meaning of the page.

A single H1 is the main heading of a page. It should summarize the central topic without competing with other main headings inside the same document.

A soft 404 is a page that appears to work, but does not actually provide useful content. The server responds as if everything is fine, although the user or bot finds an empty, wrong or error-like page.

Standardized markup, usually JSON-LD, that helps search engines and AI understand entities and relationships. It helps people, search engines and AI models understand the real meaning of the page.

The meta description is a short summary of the page. It does not replace the content, but it helps explain what the user will find before entering.

Meta robots is a tag that tells bots what to do with a specific page: index it, not index it, follow its links or limit certain snippets. It is a small signal with major impact.

Mixed content happens when an HTTPS page loads resources through HTTP. The page may look secure, but some pieces are not, which can trigger warnings or reduce trust.

Consistency between what exists on desktop and mobile to avoid content loss in mobile-first indexing. It helps organize the website's base so content is easier to interpret and maintain.

Mobile-first means that the mobile version has priority in website evaluation. If something important does not appear or work on mobile, it can lose value even if it looks perfect on desktop.

A detectable 404 page clearly reports that a URL does not exist. Beyond showing a useful message to the user, it must also return the correct HTTP status.

A robots.txt directive that prevents certain bots from crawling a specific path. It helps confirm whether important pages can be discovered without obstacles or contradictory signals.

E-E-A-T brings together signals of experience, expertise, authority and trust. It helps assess whether a page looks reliable, who is behind it and whether the content deserves to be taken seriously.

A set of signals such as authorship, date and responsibility that increase algorithmic trust. It helps turn a technical review into a simple, verifiable reading.

An identifiable person, organization, place, product or concept that AI can recognize and relate to other elements. It helps people, search engines and AI models understand the real meaning of the page.

Headings are the H1, H2, H3 and following titles that organize a page. They divide content into readable sections that are easier to interpret.

An LLM is a language model capable of interpreting and generating text. It does not “understand” like a person, but it detects patterns, context and relationships between words and ideas.

Noindex is an instruction asking that a URL not appear in search results. It is used when a page can exist for the user, but should not be part of the index.

RAG is a system that retrieves information before generating an answer. Instead of answering only from model memory, it searches for relevant fragments and uses them as context.

Robots.txt is the file that guides bots on which areas they may crawl and which areas should be avoided. It is useful, but a badly placed rule can hide important parts of the website.

A 301 redirect indicates that a URL has moved permanently. It transfers authority, links and signals from the old URL to the new one so bots and users reach the correct content.
