Chapter 12: Glossary — The Vocabulary, Without the Mystique

Plain definitions, in the order a store owner meets the ideas. Where a term is a tool company's invention rather than a Google concept, it says so.

allintitle: — A Google search operator. allintitle: phrase returns only pages whose title tag contains all the phrase's words. Used in Chapter 3 to estimate how many pages deliberately target a keyword. The result count is an unstable estimate, not a measurement.

Anchor text — The clickable words of a link. Descriptive, natural anchor text ("our cork mat care guide") tells readers and Google what the destination covers. A site whose incoming anchors are all exact sales keywords looks manufactured, because it usually is.

Backlink — A link from another website to yours. Chapter 10's subject. Quality is defined by relevance, real traffic, editorial placement, and the linking site's own reputation — not by count.

Canonical tag (rel="canonical") — A line of code declaring "this URL is the official version of this page." Stores use it to consolidate variant, filter, and duplicate URLs onto one primary page (Chapter 8).

Cannibalization — When two of your own pages target the same search intent and split each other's rankings. Prevented by keyword mapping (Chapter 4); cured by re-aiming, merging, or redirecting.

Click-through rate (CTR) — Clicks ÷ impressions, in Search Console. A ranking with poor CTR usually has a title/description problem (Chapter 7).

Core Web Vitals — Google's standardized user-experience metrics: loading (LCP), responsiveness (INP), and visual stability (CLS). A minor ranking input and a major conversion factor (Chapter 8).

CPC (cost per click) — What advertisers pay Google for one click on a keyword. Used in Chapter 2 as an indirect signal of buyer intent: advertisers pay for clicks that convert.

Crawl — Google's automated visiting of pages to discover and re-read them. Pages cannot rank if they cannot be crawled and indexed. Crawl attention is finite; duplicates and filter-URL sprawl waste it (Chapter 8).

Domain Rating (DR) — Ahrefs' 0–100 estimate of a site's link authority. A tool metric, not a Google metric — useful for comparing competitors (Chapter 3's "low-DR site in the top 5" signal), meaningless as a goal in itself.

Faceted navigation — Store filtering (color, size, price, sort) that generates a new URL per combination. Powerful for shoppers, dangerous for crawl budget without canonical/noindex control (Chapter 8).

Heuristic — A rule of thumb that works often enough to be useful and is not a law. This book's thresholds — allintitle under 50, ~1,500-word category pages — are heuristics, and are labeled as such wherever they appear.

Impressions — In Search Console: how many times your page appeared in results. The earliest honest success metric in SEO, because Google expands impressions before it improves positions (Chapters 9–10).

Indexing — Google storing a page in its database so it can appear in results. If a page is not indexed, nothing else in this book matters for it. Check in Search Console (Chapter 8).

Intent (search intent) — What the searcher is trying to do: buy, compare, or learn. The organizing unit of keyword mapping — one intent, one page (Chapter 4).

Internal link — A link between two pages of your own site. The mechanism of topical structure (Chapter 5) and the cheapest support you can give a near-miss page (Chapter 9).

Keyword Golden Ratio (KGR) — A practitioner formula (popularized by Doug Cunnington): allintitle count ÷ monthly search volume; ratios under ~0.25 are treated as promising. A cousin of Chapter 3's flat threshold, with the same heuristic status.

Keyword mapping — Assigning each search intent to exactly one owning page, recorded in a spreadsheet. Chapter 4; Worksheet 1.

Long-tail keyword — A longer, specific, lower-volume phrase ("extra thick yoga mat for bad knees") with usually higher intent and lower competition than head terms ("yoga mat"). The economic foundation of small-store SEO.

Meta description — The short summary shown under your title in search results. Does not directly affect rankings; strongly affects whether rankings become clicks (Chapter 7).

Near-miss page — One of your pages ranking around positions 8–20 for a mapped keyword. The highest-value improvement targets in the monthly loop (Chapter 9).

noindex — A directive telling Google not to include a page in results, while still allowing it to be crawled. The correct tool for pages that must exist for users but should never rank (Chapter 8).

Redirect (301) — A permanent forwarding of one URL to another, passing most of its accumulated value. Used when pages move, merge, or are deleted with history (Chapters 8–9). A 302 is the temporary version.

Rich result — An enhanced search listing (stars, price, availability) powered by schema markup. Eligibility requires accurate structured data (Chapter 7).

robots.txt — A small file at your site's root instructing crawlers where not to go. Powerful, easy to get wrong, and not a removal tool (Chapter 8).

Schema / structured data — Standardized labels added to a page's code describing its content (Product, price, rating, breadcrumbs) in machine-readable form (Chapter 7).

Semantic SEO — Optimizing a page for a topic — its full set of subtopics, attributes, vocabulary, and questions — rather than for one repeated keyword. Chapter 6.

SERP — Search engine results page. "The SERPs" is practitioners' shorthand for Google's results for a given query.

Sitemap (XML) — A file listing your site's important URLs, submitted to Search Console to help Google find and prioritize them. Should contain only live, canonical URLs (Chapter 8).

Title tag — The HTML title of a page; displayed as the headline of its search result and a major relevance signal. One per page, unique, keyword-led (Chapter 7).

Topical authority — The earned perception — by Google and by readers — that a site covers a subject completely and coherently. Built physically from hub-and-cluster structure (Chapter 5) and coverage (Chapter 6). Not a score any tool can sell you.

Merchant Center / product feed — Google's program through which stores submit structured product data (the feed: titles, prices, images, availability), powering Shopping-tab and free product listings (Chapter 1). Separate from crawling: a page can rank organically with no feed, and a feed can list products whose pages rank nowhere — which is why the book builds pages first.

Disavow — A Search Console tool for telling Google to ignore specific links pointing at your site, used when toxic links (Chapter 11's $50 packages) have already been acquired. A cleanup tool of last resort, not a routine practice — most small stores will never legitimately need it, which is itself an argument for never buying the links that make it necessary.

E-E-A-T — Experience, Expertise, Authoritativeness, Trustworthiness: the qualities Google's quality guidelines ask its human raters to look for, and a useful shorthand for what Chapters 6–7 build in practice — first-hand product knowledge, accurate specifics, real reviews, and a store that behaves like a business rather than a funnel.

Search volume / keyword difficulty — The two headline numbers of every keyword tool: an estimate of monthly searches for a phrase, and a proprietary score (each tool computes its own) estimating how hard ranking would be. Both are modeled guesses built on partial data. Chapter 2 explains why neither outranks buyer intent; Chapter 3 replaces blind trust in difficulty scores with inspecting the actual results.

Winning Formula — The source method's four-signal keyword test (Chapter 3): a low-authority site in the top 5; irrelevant results ranking; stale pages holding positions; a low allintitle count.
