Glossary
Definitions of the technical and legal terms used across this site. Each definition matches how the term is used in the sourced writing here.
- GEO (generative engine optimisation)
- The body of work aimed at getting a page or person cited as a source in answers produced by AI engines.
- Not a continuation of classic search optimisation: the measured factors differ and some run the other way. Keyword stuffing was the only method measured to reduce visibility.
- Detail →
- Dwell time
- The time a member spends on a post in the feed; LinkedIn has stated since 2020 that it uses this as a ranking signal.
- Two measures exist: on-feed dwell, starting when at least half the post is visible, and after-click dwell. The threshold in seconds has never been published.
- Detail →
- Long dwell
- One of two objectives LinkedIn’s ranking model predicts: time on a post above a threshold that depends on post type.
- The other is contribution — a like, comment or reshare. Both are named in LinkedIn’s February 2026 paper.
- Detail →
- Second pass ranker
- The LinkedIn model that merges candidates ordered by each content source into a single personalised feed list.
- Because of this structure there is no single “algorithm”. A post must first enter a candidate pool and then be ordered within it; it can be dropped at either stage for different reasons.
- Detail →
- Earned media
- Content published about a person or organisation by an independent outlet without payment.
- Roughly 84% of citations in AI answers come from this kind of content; paid content accounts for 0.3%. It is the heaviest measured factor in personal-brand visibility.
- Detail →
- OAI-SearchBot
- OpenAI’s search crawler. Whether a page can appear as a source in ChatGPT answers depends on this bot being able to crawl it.
- Frequently confused with GPTBot. GPTBot is for model training; blocking it does not directly end search visibility. OpenAI explicitly recommends allowing OAI-SearchBot.
- Detail →
- GPTBot
- The crawler OpenAI uses to train its foundation models.
- Blocking it means the content stays out of training data. It is not the bot that determines whether you appear in search answers.
- Detail →
- llms.txt
- A plain-text file proposed for the site root to summarise a site’s content for AI models.
- No measured evidence in its favour. Google’s John Mueller stated no AI system uses it, and no vendor mentions it in crawler documentation. It has not been shown harmful either.
- Detail →
- robots.txt
- The root-level text file stating which crawlers may access which parts of a site.
- A permission mechanism, not a guarantee: OpenAI states robots.txt rules may not apply to user-initiated fetches, and a CDN can block a bot independently of robots.txt.
- Detail →
- Structured data (schema.org)
- Markup that describes what a page is about in a form machines can read.
- In a controlled study of 1,885 pages already receiving citations, the effect on AI citations was indistinguishable from zero. Discovery was not tested. Treat it as hygiene, not leverage.
- Detail →
- Entity page
- A crawlable page describing a person or organisation with a one-sentence definition, verifiable records and links to their other profiles.
- The precondition for AI visibility. A login wall, JavaScript-only rendering and a noindex tag each close this threshold.
- Detail →
- Title field
- The structured “Title” field in a LinkedIn experience entry; the hard filter in recruiter search reads it directly.
- Not the same as the headline. The headline appears only in keyword search and is truncated at around sixty characters on the results card.
- Detail →
- Standardised skill
- A skill entry chosen from LinkedIn’s own list and therefore recognised by search.
- A skill typed as free text is not recognised. Pinning the three to five most directly tied to your target title decides what surfaces on the card.
- Detail →
- Impression
- The number of times a post was displayed on someone’s screen.
- Across 476,000 personal-profile posts the median was about 840. The distribution is skewed: the 94th percentile begins at 15,000 impressions.
- Detail →
- Engagement rate
- Reactions, comments and shares on a post as a proportion of its impressions.
- It can move opposite to reach: in the same measurement it falls from 2.86% in the bottom 80% of posts to 0.89% in the top 5%. Bigger reach can mean thinner attention.
- Detail →
- Link preview card
- The card with a title and image generated automatically when a link is attached to a post.
- In a 567,000-post measurement, posts with a card had a median of 414 impressions while plain in-body URLs slightly outperformed posts with no link. The effect may come from the format.
- Detail →
- Browser automation
- A tool acting on a platform through the user’s browser session instead of the official API.
- Section 8.2 of the LinkedIn User Agreement prohibits it directly, and the party bound is the user, not the vendor. Consequences are usually staged: temporary limits, feature restrictions, suspension.
- Detail →
- r_member_social_feed
- The LinkedIn permission that would let an application read comments on a member’s behalf.
- Granted only to selected developers. Writing comments sits in the open category while reading them does not, which is why “automatic comment replies” cannot be delivered through the API.
- Detail →
- Public disclosure (alenileştirme)
- Under Turkey’s Law 6698, personal data being made publicly available by the data subject’s own will.
- The regulator’s settled reading is that such data may only be processed in a way connected to and limited by the purpose of disclosure. Being public does not mean processable for any purpose.
- Detail →
- Data controller
- Under Law 6698, the natural or legal person determining the purposes and means of processing personal data.
- The burden of proof sits here. In published decisions, a controller that cannot document the processing condition it relied on loses.
- Detail →
- VERBİS
- Turkey’s public registry of data controllers, which controllers above a threshold must join.
- Exemption applies to controllers with fewer than 50 employees and an annual balance sheet under 100 million TRY whose main activity is not processing special-category data.
- Detail →
- Canonical tag
- The tag stating which address counts as the original when the same content is reachable at several URLs.
- It matters on bilingual sites: Googlebot carries no cookies, so if the language decision is not made from the path, two languages collide on one address and indexing becomes ambiguous.
- Sitemap
- An XML file listing a site’s crawlable addresses in machine-readable form.
- Submitted separately to each search console. Bing is no longer the main lever for ChatGPT but it is the index Microsoft Copilot draws on.
- Detail →
- Query-answer match
- A heading on a page matching, word for word, the question people type into a search box.
- It scores as the highest-impact factor in GEO measurements. Writing headings as questions is different from — and works opposite to — keyword repetition.
