Marketing, e-commerce and advertising terms starting with the letter C. Each one explained in plain language, with links to related terms.

Cachecache memory

The place where the browser stores copies of pages already visited. On a repeat visit it does not have to fetch everything from the server again, so the page loads faster and the server saves bandwidth.

This is controlled by HTTP headers - mainly "Cache-Control" and "Expires". Set incorrectly, they work the other way: the user keeps seeing an old version of the page long after the content has been updated.

Canonical

An HTML tag specifying which URL is the primary version of a given piece of content. It is used when several different URLs lead to the same content.

Without it, a search engine indexes the variants separately, and link equity gets split between them instead of consolidating on one URL. It is worth checking that all duplicates point to the same canonical.

Case studycase study

A description of how a specific company solved a specific problem. In marketing it is used to demonstrate a service's effectiveness through an example instead of a claim.

It works when it includes the starting point, the steps taken, and numbers at the end. A case study without figures is a story, not proof.

Click & collect

A shopping model combining the convenience of an online store with immediate pickup. The customer reserves a product online and picks it up themselves, without waiting for a courier and usually without a delivery fee.

It makes sense with a network of physical locations or a warehouse that allows pickup. It requires accurate stock levels - promising pickup "right away" when the item is not in stock costs more than not offering the option at all.

Cloaking

A technique that serves search-engine crawlers different content than what a human sees. The goal is a higher ranking earned on content the user will never actually see.

Directly against Google's guidelines and punished with removal from the index. It belongs to the Black Hat SEO toolkit - the cost of getting caught is higher than the benefit of a short-lived boost.

CLVCustomer Lifetime Value

A metric estimating how much a customer will bring a company over the entire duration of the relationship. It is calculated from average transaction value, purchase frequency, relationship length, and the cost of maintaining it.

It determines how much can be spent to acquire a customer. High CLV justifies investment in retention and loyalty programs; low CLV shifts budget toward acquiring new customers.

It is a forecast, not a fact. It needs to be recalculated regularly, since it changes along with margin and customer behavior.

CMSContent Management System

Software that lets you add, edit, and remove content on a site without writing code. It consists of an admin panel and an engine that displays that content.

The most popular CMS is WordPress. The choice of system should follow from who will be editing the content and how often - not from how popular a solution is.

Content marketingcontent marketing

A strategy of creating and distributing content that answers audiences' real questions, instead of selling directly. The formats vary: articles, video, podcasts, e-books, webinars.

It serves the stage where a customer is not ready to buy yet but is already looking for information. Along the way it builds organic visibility, since this content gets indexed by search engines.

Contextual advertising

A form of advertising displayed on pages whose subject matter matches the current visitor's interests — for example, an ad for fishing gear on a blog about fishing.

Thanks to a relevant context, it is usually more effective and cheaper per result than advertising shown with no connection to the page's content.

Conversion

An event counted as a goal: a purchase, a submitted form, a phone call, a signup, a download. What counts as a conversion follows from the business model, not from the analytics tool.

The most common mistake is counting everything the same way. If a click on a phone number weighs as much as a purchase worth several thousand, the report stops saying anything about money.

Copywriting

Creating content whose job is to grab attention and drive a specific action. It covers research into the target audience, concept, the text itself, and testing what works.

Good copywriting requires understanding the product and the customer, not just language skill. In practice, the biggest improvements usually come from talking to the person who sells that product day to day.

Core Web Vitals

A set of three metrics developed by Google: LCP (loading time of the largest element), FID (response time to the first interaction), and CLS (layout stability during loading).

Since 2021 they have been an official ranking factor. In practice, though, what matters most is what the user sees - a page that jumps around while loading puts people off regardless of its search ranking.

CPCCost Per Click

A way of billing campaigns where a cost is incurred only when someone clicks the ad - the impression itself is free. The standard model on Google Ads, Allegro Ads, and social-media advertising systems.

It lets you control budget precisely, but on its own it says nothing about profitability. A click costs the same whether or not it turns into a sale - which is why CPC needs to be read together with conversion and ROAS.

Crawl budget

The pool of resources a search engine allocates to crawling a site. On large sites, it determines whether all subpages even make it into the index.

It gets wasted on things that should not be indexed at all: 404 errors, redirect chains, duplicates, filters generating thousands of URLs. A clean sitemap and clean URLs work in the opposite direction.

CRMCustomer Relationship Management

A tool that gathers the history of contact with a customer: calls, quotes, orders, service tickets. It lets sales run without relying on a rep's memory or their personal inbox.

The value of a CRM depends directly on the discipline of entering data. A system filled in sporadically produces reports that decisions cannot be based on.

CROConversion Rate Optimization

Systematically improving a site to raise the share of users who take the intended action: buying, filling in a form, calling. It is based on analyzing where users drop off and A/B testing successive versions.

Usually cheaper than increasing traffic. Raising conversion from 1% to 2% has the same effect as doubling the ad budget, except the cost is one-time.

Cross-selling

Offering a customer products related to their purchase - accessories, consumables, service add-ons. It raises cart value without the cost of acquiring a new customer.

It requires a genuine link between the products. Suggestions picked at random lower trust and can be worse than not showing any.

CSSCascading Style Sheets

A style language describing how content written in HTML should look. It separates the visual layer from the document's structure, so changing the look does not require touching the content.

Cascading means rules inherit and override each other according to a defined hierarchy. That is the source of both the system's flexibility and most of the hard-to-trace bugs in a page's layout.

CTACall to Action

A button or line telling the user exactly what to do: buy, fill in a form, download a resource, call. The element the rest of the subpage is built around.

An effective CTA is singular, visible, and specific. "Learn more" says nothing - "Order an audit" says what will happen after the click.

CTRClick Through Rate

A metric showing what share of people who saw an ad or a search result clicked on it. With 1,000 impressions and 50 clicks, CTR is 5%.

It measures how relevant the message is to the audience, not the quality of the offer. A high CTR combined with low conversion usually means the ad promises something different from what the user finds after clicking.

Customer Journey Mapcustomer journey map

A representation of the customer's entire path, marking touchpoints with the company, communication channels, needs, and points of friction.

The map's value lies in showing the handoffs between departments - most customers are lost not within a stage, but at the boundary between marketing, sales, and service.
