64 sales, marketing and SEO terms, each defined in plain English in its first sentence.

C

Clicks

Clicks count how many times people click an ad or a search result that leads to your site. In Google Ads a click is counted when someone clicks your ad, even if your website then fails to load, and it is the base for metrics like click-through rate and cost per click.

CNAME record

A CNAME (canonical name) record is a DNS record that makes one domain name an alias of another. When someone looks up the alias, DNS follows the CNAME to the target name and returns that name's IP address.

Complaint (Spam Complaint)

In email marketing, a complaint (or spam complaint) is recorded when a recipient marks your message as spam or junk in their inbox. Mailbox providers use complaint rates to decide whether your future email reaches the inbox, and Gmail and Yahoo ask bulk senders to keep the rate below 0.3%.

Conversion Rate (CVR)

Conversion rate (CVR) is the percentage of visitors, sessions or ad clicks that end in a desired action, such as a sign-up, demo request or purchase. You calculate it by dividing conversions by the total number of visitors (or clicks) and multiplying by 100.

Conversion Rate Optimization (CRO)

Conversion rate optimization (CRO) is the systematic process of increasing the share of website visitors who complete a desired action, such as booking a demo, starting a trial or buying. It works by finding what stops people from converting and testing changes that remove those obstacles.

CSS (Cascading Style Sheets)

CSS (Cascading Style Sheets) is the language that controls how a web page looks, including colours, fonts, spacing and layout. HTML gives a page its content and structure; CSS styles it.

Customer Acquisition Cost (CAC)

Customer acquisition cost (CAC) is the average amount a business spends on sales and marketing to win one new customer. You calculate it by dividing the total acquisition spend in a period by the number of new customers won in that period.

Customer Lifetime Value (CLV or LTV)

Customer lifetime value (CLV or LTV) is an estimate of how much a customer is worth to a business over the whole relationship, ideally measured as profit rather than revenue. It helps decide how much you can afford to spend to win and keep a customer.

Page Authority (PA)

Page Authority (PA) is a score from 1 to 100, developed by the SEO software company Moz, that predicts how well a single web page will rank in search results. It is based mostly on the links pointing to that page, and it is not a Google ranking factor.

Pageview

A pageview is one load of a web page in a browser that your analytics tool records. Every load counts, so one visitor who opens three pages, or reloads the same page three times, creates three pageviews. Google Analytics 4 reports pageviews under the metric name Views.

Paid Inclusion

Paid inclusion is a search marketing model where a website pays a search engine to be added to its index, reviewed faster or crawled more often, without being promised a higher ranking. It was common in early web search and has largely disappeared; Google says it does not accept payment to crawl a site more often or rank it higher.

Pay Per Click (PPC)

Pay per click (PPC) is an advertising model where the advertiser pays each time someone clicks an ad, rather than when the ad is shown. It is most common in search ads such as Google Ads and Microsoft Advertising, where ads compete in an auction for each search.

Pay Per Sale (PPS)

Pay per sale (PPS), also called cost per sale, is a payment model in which an advertiser pays a publisher or affiliate only when a visitor they referred makes a purchase. The payment is usually a percentage of the sale, though some programs pay a flat amount per sale.

Phishing

Phishing is a scam in which an attacker poses as a trusted person or organisation, usually by email, text message or phone, to trick people into clicking a harmful link, opening an infected attachment or handing over passwords, money or other sensitive information.

Private Blog Network (PBN)

A private blog network (PBN) is a group of websites, often built on expired domains, that one person or company controls and uses to link to a main site to boost its search rankings. Google treats PBN links as link spam.

Product Matrix (Ansoff Matrix)

A product matrix, usually meaning the Ansoff matrix or product-market matrix, is a two-by-two grid that sorts growth options by whether you sell existing or new products in existing or new markets. Its four strategies are market penetration, market development, product development and diversification.

R

Recipient

A recipient is the person or organisation a message is sent to. In email, recipients are listed in the To, Cc and Bcc fields; in email marketing, the recipients are the subscribers on your list who receive a campaign.

Reciprocal Links

Reciprocal links are links two websites place to each other, usually because the owners agreed to swap them. A few that make sense for readers are normal, but Google treats excessive link swaps made only for ranking as link spam.

Referring URL

A referring URL (or referrer) is the address of the page a visitor was on just before they clicked through to your page. Browsers pass it in the HTTP Referer header, and analytics tools use it to show which sites send you traffic.

Return Path

The return path is the email address that bounces and other delivery failure notices are sent to. It comes from the SMTP "MAIL FROM" command, is stored in a Return-Path header on delivery, and its domain is the one SPF checks and DMARC compares with your From address.

Returning visitors

Returning visitors are people who come back to a website after an earlier visit. Google Analytics 4 counts them as returning users, which it defines as users who have started at least one previous session.

Run of Network (RON)

Run of network (RON) is a way of buying ads in which your ad can appear on any website in an ad network, without choosing specific sites or placements. It gives high reach at a low price, in exchange for very little control over where the ad shows.

Run of Site (ROS)

Run of site (ROS) is a way of buying display ads in which your ad can appear on any page of one website, in any open ad slot, instead of in a fixed position. You give up control over where the ad shows and usually pay a lower rate in return.

S

Search Engine Positioning

Search engine positioning is the work of improving where specific pages appear in organic search results for the queries that matter to a business. It is a part of SEO focused on rank for chosen keywords, measured in Google Search Console as average position.

Search Query

A search query is the exact word or phrase someone types or speaks into a search engine. Marketers study queries to learn what people want and then choose the keywords they will target.

Search Term

A search term is the exact word or phrase a person types or speaks into a search engine. It differs from a keyword, which is the word or phrase an advertiser or SEO chooses to target. People create search terms. Marketers choose keywords.

Sender Score

Sender Score is a reputation rating from 0 to 100 for an email-sending IP address, calculated by the email company Validity (formerly Return Path). A higher score means the IP's recent sending looks more trustworthy compared with other senders.

Service Level Agreement (SLA)

A service level agreement (SLA) is an agreement between a service provider and a customer that sets measurable service targets, such as uptime or response time, and states what happens if the provider misses them. SLAs can also be internal, for example between marketing and sales.

Skyscraper Ad

A skyscraper ad is a tall, narrow display ad that runs down the side of a web page, most often 160 x 600 pixels (wide skyscraper) or 120 x 600 pixels (skyscraper). It sits in the sidebar next to the main content.

Social Proof

Social proof is the tendency to copy what other people do or approve of, especially when we are unsure what to choose. In marketing, it means showing evidence that others already use and trust a product, such as reviews, case studies, customer logos and testimonials.
