Canonical URL
The version of a page you tell search engines is the master copy. Set with a <link rel="canonical"> tag. Critical when the same content lives at multiple URLs (with/without trailing slash, query strings, location pages). Done wrong, you bleed authority across duplicate URLs.
Case Acceptance
The percentage of presented treatment plans the patient agrees to. Marketing only fills the chair — case acceptance turns the visit into production. A healthy practice runs 70%+ on full treatment plans. Below 50% is a sales/treatment-presentation problem, not a marketing problem.
ChatGPT Search
OpenAI's web search inside ChatGPT. Cites a small number of sources per answer. Practices show up here by being entity-recognizable (Wikidata, sameAs links), having unique content (not boilerplate), and being part of authoritative lists ("best dentist in [city]"). Different ranking signal mix than Google.
Citation (AI Search)
A direct reference to your site inside an AI engine's answer — name + link, usually as a footnote or inline source. Different from local SEO citations. The new currency of visibility: rankings move clicks, citations move trust.
Citation (Local SEO)
A mention of your practice's name, address, and phone (NAP) on a third-party directory or aggregator — Yelp, Healthgrades, Yellow Pages, BBB. Consistency across citations is a local ranking signal. Note: this is the older meaning. AI search uses "citation" differently.
Conversion Rate
Percentage of website visitors who take the desired action — usually book a consultation or call. Dental industry median sits around 2-3%. Sites with weak hero copy, slow load, or buried phone numbers run under 1%. Above 5% means landing pages are doing real work.
Core Web Vitals
Google's page experience metrics: Largest Contentful Paint (LCP, load speed), Interaction to Next Paint (INP, responsiveness), and Cumulative Layout Shift (CLS, visual stability). All three need to be in the green or rankings take a hit. Dental sites running heavy hero videos usually fail LCP.
CPA (Cost Per Acquisition)
Also: CAC, Customer Acquisition Cost
Total marketing spend divided by new patients acquired. The single most important number in dental marketing. National median: $250-$400 per new patient. High-end cosmetic/implant practices can sustain $600-$1,200 because LTV justifies it. Watch CPA monthly, optimize against LTV.
Crawl Budget
The amount of time Googlebot will spend crawling your site per day. Tiny sites don't worry about this. DSOs with 50+ location pages absolutely do. Burn crawl budget on duplicate location pages and your fresh content never gets indexed in time.
