Glossary
Short definitions for the terms on this site. Each page states what the term means, then how ScrollLaunch uses it.
DofollowA dofollow link is a normal hyperlink that can pass ranking signals to the page it points at. Search engines may use it as a vote for that URL.NofollowA nofollow link tells crawlers not to treat the link as an endorsement. The rel attribute usually includes nofollow, and often ugc or sponsored.UGCUGC means user-generated content. rel=ugc marks a link that a user, not the site editor, created.Product reviewsProduct reviews on ScrollLaunch are signed-in, visit-gated star ratings plus a written take. They live at /products/[slug]/reviews. AggregateRating structured data is emitted only from published reviews.Link equityLink equity is the ranking value a link can pass from one page to another. Dofollow links can pass it. Nofollow links generally do not.BacklinkA backlink is a link from another website to yours. Quality, relevance, and whether the link is dofollow all change how much it helps.Referring domainA referring domain is a unique website that links to you. Ten links from one domain still count as one referring domain in most SEO tools.Anchor textAnchor text is the visible, clickable words of a link. Exact-match anchors repeated sitewide can look unnatural.Domain RatingDomain Rating (DR) is Ahrefs' 0-100 score for the strength of a site's backlink profile.

Other URLs that show the same content should point at it with rel=canonical.Soft 404A soft 404 is a page that looks empty or useless but still returns HTTP 200. Search engines may drop it, and a lot of them can hurt the site.SitemapA sitemap is an XML list of URLs you want crawled.

It does not remove a URL from the index by itself.IndexNowIndexNow is a protocol for telling Bing and other partners that a URL changed, by POSTing the URL and a key file on your host.llms.txtllms.txt is a plain-text index of a site for language models. It lists the pages and machine-readable files an agent should read first.ai.txtai.txt is a policy file that tells AI systems what they may summarise, quote, and cite, and what they must not invent.Markdown twinA markdown twin is the same page served as text/markdown so an agent can read it without parsing HTML.MCPMCP (Model Context Protocol) is a way for AI clients to call tools over HTTP. A server lists tools, and the client calls them with JSON.JSON-LDJSON-LD is structured data embedded in a page as JSON. It describes the page to search engines and answer engines.FAQ schemaFAQ schema (FAQPage) marks real questions and answers that are visible on the page. The text in the markup must match the text people can read.Open GraphOpen Graph tags (og:title, og:description, og:image) control how a URL looks when it is shared in chat and social apps.Meta descriptionA meta description is the short summary search engines may show under a title. It does not directly rank the page, but it affects clicks.Title tagThe title tag is the blue link text in search results. Keep the important words at the front and stay near 60 characters once the brand suffix is added.HreflangHreflang tells search engines which language or regional URL to show. It is only useful when you actually publish those translations.Alt textAlt text is the written replacement for an image. Screen readers use it, and search engines use it to understand the image.Internal linkAn internal link points to another page on the same site. It helps visitors and spreads crawl attention across the catalog.Crawl budgetCrawl budget is how many URLs a search engine will fetch from your site in a period.

They prefer pages that state a fact plainly and can be cited.Featured snippetA featured snippet is a short answer Google lifts into the result. Lists, tables, and a direct first sentence are the usual formats.People Also AskPeople Also Ask is the question box in Google results. Pages that ask the question as a heading and answer it immediately are easier to use there.E-E-A-TE-E-A-T stands for experience, expertise, authoritativeness, and trust. It is a quality framework, not a single ranking score.Core Web VitalsCore Web Vitals are Google's page-experience measures: loading (LCP), interactivity (INP), and visual stability (CLS).ISO weekAn ISO week is a week numbering system that starts on Monday.
