- CPM
- Cost per mille — price for a thousand ad impressions, the base currency of display, audio and video advertising. Publisher CPMs vary by format, viewability, audience quality and how the inventory is sold.
- CPC
- Cost per click — the advertiser pays only when someone clicks. Common in search and performance campaigns; it shifts risk from advertiser to publisher, since unclicked impressions earn nothing.
- RPM
- Revenue per mille — what the publisher actually earns per thousand pageviews or sessions after fill rate, unsold inventory and fees. RPM, not CPM, is the number that tells you whether a page pays for itself.
- Fill rate
- Share of available ad slots that actually get filled with paying ads. A high CPM on a 40% fill rate can earn less than a modest CPM sold out.
- Viewability
- Whether an ad was actually seen — the MRC standard is 50% of pixels in view for one second for display, two seconds for video. Low viewability depresses price and gets inventory blocklisted.
- Direct-sold vs programmatic
- Direct-sold means a salesperson negotiates an insertion order with a brand or agency at a premium; programmatic means the impression is auctioned in milliseconds. Direct pays more per impression and takes headcount; programmatic scales and commoditizes.
- Header bidding
- Running a simultaneous auction across multiple demand sources in the page header before calling the ad server, so every buyer bids on the same impression instead of a waterfall. It raised publisher yield and added latency and complexity.
- SSP / DSP
- A supply-side platform sells the publisher's inventory into the exchanges; a demand-side platform is what the advertiser uses to buy it. The spread between what the buyer pays and the publisher receives is the ad-tech tax.
- First-party data
- Information a publisher collects directly from its own audience — registrations, subscriptions, newsletter signups, on-site behavior, declared interests. It is the durable asset when third-party identifiers fail, and it requires a value exchange to obtain.
- Consent / CMP
- A consent management platform captures and records a user's permission for tracking and data use under GDPR, ePrivacy and US state privacy laws. Consent rates directly determine how much addressable inventory a publisher has.
- Cookie deprecation
- The long-running removal of third-party cookies from browsers. Safari and Firefox blocked them years ago; Google reversed course on eliminating them in Chrome in 2025 and later retired parts of its Privacy Sandbox — but the direction of travel toward first-party data and contextual targeting did not reverse with it.
- Paywall: hard, metered, dynamic
- Hard blocks everything behind payment; metered gives a set number of free articles; dynamic decides per user and per article using propensity models. Dynamic wins on revenue and requires data most small publishers do not have.
- Freemium
- Some content free forever, premium content or features paid. The free tier is the acquisition engine, not charity — and the split has to be drawn where the paying audience feels the value, not where traffic is highest.
- Subscriber acquisition cost (SAC)
- Fully loaded cost to win one paying subscriber, including discounts, marketing and payment fees. Compared against lifetime value, it sets how aggressively a publisher can spend to grow.
- Churn
- Rate at which subscribers cancel. Voluntary churn reflects unmet value; involuntary churn is failed payments and is fixable with dunning and card updaters — often the cheapest retention win available.
- LTV
- Lifetime value — expected gross profit from a subscriber over their whole tenure. A healthy consumer media business wants LTV comfortably above SAC and a payback period measured in months, not years.
- Engaged time
- Actual attention spent on a page, measured by activity signals rather than tab-open duration. Engaged time predicts subscription and return visits far better than pageviews and is the metric Chartbeat and Parse.ly popularized.
- Scroll depth
- How far down the page a reader gets. Used to place ads where they will be seen, judge whether long-form is working, and separate genuine readers from bounce traffic.
- Recirculation
- Share of readers who go on to a second piece of content. It converts one-off search or social arrivals into sessions and habits, and it is the lever most under a publisher's own control.
- Referral traffic collapse
- The structural decline of visits arriving from search and social. Platforms deprioritized news links, and AI answers absorbed the informational query — so publishers built on borrowed reach lost the audience they thought they had.
- AI Overviews and zero-click
- Google's AI-generated answers at the top of results, which satisfy the query without a click. Pew's 2025 analysis found users clicked a result on roughly 8% of visits with an AI summary present versus about 15% without — the mechanism behind the referral collapse.
- SEO vs SGE / AEO
- Classic SEO optimizes for a ranked list of links; answer-engine optimization aims to be the source an AI system cites and quotes. Practically it means clear structure, direct answers, factual precision, entity and schema markup, and being the citable primary source rather than the aggregated summary.
- E-E-A-T
- Experience, Expertise, Authoritativeness, Trust — Google's quality-rater framework. It is not a ranking dial but a description of signals: real bylines, credentials, sourcing, corrections and about pages that make a site verifiably accountable.
- Syndication
- Licensing your content to run on someone else's property, or republishing theirs on yours. Adds reach and revenue; done carelessly it creates duplicate-content and canonical problems and trains the aggregator to outrank you.
- Licensing
- Selling rights to reuse content — wire and syndication deals, archive licensing, and now AI training and retrieval licenses. It converts an archive from a sunk cost into a recurring revenue line, and defines what a publisher gives away by default.
- MFA sites
- Made-for-advertising sites — low-quality, ad-cluttered pages built purely to arbitrage programmatic spend. Studies have found a meaningful share of open-web ad budgets landing there, which is why brand-safety and inclusion lists now matter to legitimate publishers' pricing.
- Brand safety and suitability
- Keeping ads away from content a brand deems inappropriate. Blunt keyword blocklists routinely defund legitimate news coverage of hard subjects, making 'suitability' — context-aware judgment — the fight publishers care about.
- Sponsored content
- Editorially formatted content paid for by a brand. It must be labeled clearly, is usually produced by a separate branded-content studio, and gets its credibility from the wall between that studio and the newsroom.
- Native advertising
- Paid placements that match the form and feel of surrounding content, from in-feed units to recommendation widgets. Performance depends on genuine relevance; disclosure is a legal requirement, not a design preference.
- FTC disclosure
- US Federal Trade Commission rules requiring material connections between endorser and advertiser to be disclosed clearly and conspicuously — 'ad' or 'sponsored' up front, not buried in hashtags. Applies to publishers, creators and affiliate content alike.
- Embargo
- An agreement that information supplied in advance will not be published before a set time. It gives reporters time to do the work properly; breaking one costs future access, and blanket embargoes are increasingly refused by newsrooms.
- Byline
- The named author credit. Beyond attribution it is an accountability and E-E-A-T signal — which is why author pages with credentials, contact details and a body of work now carry real search and trust weight.
- Fact-check
- Verification of claims before publication, or structured evaluation of public claims after. Either way it needs a documented process, named sources and a published methodology to be worth anything to readers or to search systems.
- Correction policy
- The published rule for how errors are fixed and disclosed — corrections, clarifications and updates, dated and visible rather than silently edited. Transparent correction is one of the strongest available trust signals.
- Editorial independence
- The principle that coverage decisions are not dictated by advertisers, owners or funders. In practice it is enforced by governance — written policies, disclosed funders, and someone senior whose job is to say no.
- Church and state
- The industry's shorthand for the separation between editorial and business operations. It has been eroded by branded content, affiliate commerce and events; where it is maintained, it is maintained deliberately and disclosed.
- CMS
- Content management system — the publishing platform where content is created, structured, versioned and released. Choosing it determines workflow speed, page performance, structured data quality and how easily content can be reused.
- Headless
- A CMS that serves structured content via API with no fixed presentation layer, so the same content feeds a website, apps, newsletters, screens and syndication partners. More flexibility, more front-end engineering.
- RSS
- A standard feed of a site's latest items in machine-readable form. Unfashionable and quietly essential — it powers readers, aggregators, syndication partners, automation and, increasingly, machine consumption of your content.
- Podcast RSS and dynamic ad insertion
- Podcasting still runs on an open RSS feed pointing at audio files, which is why no single platform owns it. Dynamic ad insertion stitches ads in at download time, so ads can be targeted, updated and resold across the whole back catalog.
- Downloads vs listeners
- A download is a file request; a listener is a person. IAB-certified measurement filters bots and partial requests, and platform analytics report consumption — the honest pitch cites both, since inflated download counts are the oldest trick in podcast sales.
- Watch time
- Total minutes viewed, and the completion rate behind it. Video platforms optimize recommendations for it, advertisers price against it, and it exposes the difference between a click-grabbing thumbnail and a video anyone finishes.
- AVOD / SVOD / FAST
- Ad-supported on demand, subscription on demand, and free ad-supported streaming TV — linear-style channels streamed free with ads. FAST is where library content and niche brands find distribution without a subscription business.
- Windowing
- Releasing content in sequenced windows across theatrical, premium, subscription, ad-supported and licensed tiers to maximize total value. Streaming compressed windows; profitability pressure has been re-lengthening them.
- Residuals
- Payments to writers, directors and performers when work is reused or streamed, set by union agreements. The 2023 WGA and SAG-AFTRA strikes rewrote streaming residuals and AI consent terms, and those costs now sit in every streaming P&L.
