ALSO CALLED: Cost per acquisition
Customer acquisition cost. The average amount you spend on marketing and sales to gain one new customer. Compare it to how much a customer is worth to you over time; if it costs more to get customers than they bring in, the math does not work.
Stored copies of files your browser or a website keeps so pages load faster next time. The downside is that you sometimes see an old version after making a change to your site. Clearing the cache or doing a hard refresh usually shows the new version.
ALSO CALLED: CAN-SPAM Act
Short for the Controlling the Assault of Non-Solicited Pornography And Marketing Act, the main US law covering commercial email. In general it requires honest sender details and subject lines, a physical mailing address and a working way to unsubscribe. Other countries have their own, often stricter, rules, so check what applies to you.
Watch out General info only; rules vary by country and change over time, so check current official guidance for where you and your subscribers are.
ALSO CALLED: canonical tag, rel canonical
A tag in a page's code that tells search engines which version of a page is the official one when the same content can be reached at more than one address. It keeps search engines from splitting credit between near-identical copies.
Example A product page reachable with and without tracking codes points both to one canonical URL.
The text that goes with a photo, video or carousel post. A caption can add context, tell a short story, include hashtags and give a clear call to action. On many platforms only the first line shows before "more," so that line does the heavy lifting.
Video, audio & podcasting
ALSO CALLED: Subtitles, CC
On-screen text that shows what is being said in a video. Closed captions can be turned on or off by the viewer; open captions are burned into the picture permanently. Many people watch with the sound off, and captions also make your video usable for people who are deaf or hard of hearing.
Selling, ecommerce & payments
When a payment fails because the buyer's bank or card company refuses it. Common reasons include wrong card details, not enough funds, a fraud filter, or an expired card. You usually cannot see the exact reason, and the buyer may need to call their bank.
Example A customer emails that checkout keeps saying "card declined" even though they typed everything correctly.
A single post containing several images or slides that people swipe through. Carousels work well for step-by-step tips, short lists and mini guides, because each swipe pulls the reader a little further in.
Example A seven-slide carousel walking through what to put in a family emergency binder.
A broad bucket you use to group related blog posts, like "Recipes" or "Side Hustles." Categories help readers browse and help search engines see what your site covers. Most sites do fine with a small number of clear categories.
Websites, domains & hosting
ALSO CALLED: content delivery network
Content delivery network. A group of servers spread around the world that keep copies of your site's files and deliver them from whichever server is closest to each visitor. It can make pages load faster and absorb traffic spikes.
A route you use to reach people, such as email, a social platform, search engines, podcasts, paid ads or in-person events. Beginners do better picking one or two channels and learning them well than trying to be everywhere at once.
Example My main channels are my newsletter and short videos.
Selling, ecommerce & payments
When a buyer asks their bank or card company to reverse a payment instead of asking you for a refund. The money is pulled back from you, and processors often add a fee. Too many chargebacks can get your payment account limited or closed, so clear policies and fast support matter.
Example A buyer does not recognize your business name on their statement and files a chargeback instead of emailing you.
Watch out Make sure your business name on card statements is recognizable. Confusing statement names cause chargebacks that a quick refund would have avoided.
A program you talk to by typing or speaking that replies in conversational language. Modern chatbots run on large language models and can draft, explain, and brainstorm. On a business website, a chatbot can also answer common customer questions around the clock.
Selling, ecommerce & payments
The final steps of a purchase where the buyer enters payment details and confirms the order. A short, clear checkout with no surprises loses fewer buyers. Every extra field or unexpected cost is a reason for someone to quit.
The share of subscribers or members who cancel or leave during a given period. For memberships and subscriptions it is one of the most important numbers, because losing members quietly undoes the work of gaining new ones.
Partnerships, affiliates & JVs
When a merchant takes back a commission that was already credited, usually because the customer got a refund or the sale turned out to be fraudulent. It is normal and should be spelled out in the agreement, but surprise clawbacks are a red flag.
A single instance of someone clicking or tapping a link, button or ad. Clicks show interest, not purchase. Many tools count clicks slightly differently, and some count bots.
Video, audio & podcasting
ALSO CALLED: Peaking
Audio distortion that happens when a sound is too loud for the microphone or recorder to handle, so the top of the waveform gets chopped off. It sounds harsh and crackly, and it usually cannot be fixed afterward. Turn your gain down and do a test recording before the real take.
ALSO CALLED: The cloud
Saving files on a company's servers over the internet instead of only on your own device, so you can reach them anywhere. It is handy for backups and sharing. It is still someone else's computer, so use a strong password with 2FA and keep a second copy of anything critical.
Websites, domains & hosting
ALSO CALLED: content management system
Content management system. Software that lets you build and update a website through an admin screen instead of writing code for every change. You type, upload images, and click publish; the CMS handles turning that into web pages.
Design, branding & visuals
ALSO CALLED: four-color process
Cyan, magenta, yellow, key (black). The color mode used for printing, where colors are made by layering inks. Designs made in screen colors can look duller in print, so printers often ask for CMYK files.
Websites, domains & hosting
ALSO CALLED: canonical name record, alias record
A DNS setting that points one name to another name instead of to a numeric address. It is often used to connect a subdomain, like shop.yoursite.com, to a service you use elsewhere.
Partnerships, affiliates & JVs
Two or more brands putting their names together on a product, event, or piece of content. It borrows trust from both audiences at once, so only pick partners whose reputation you would be comfortable having attached to your own name.
People who have never heard of you and have no reason to trust you yet. They need an introduction and something useful before they will consider buying, so pitching them a product right away rarely works.
Example Someone who sees your video for the first time on a random scroll is part of your cold audience.
An email sent to someone who has not signed up for your list or asked to hear from you, usually to pitch a service, partnership or collaboration. A single, personal, relevant cold email can be fine. Bulk cold email to strangers risks spam complaints and legal trouble.
Watch out Never load strangers' addresses into your newsletter tool; most providers forbid it and it can get your account shut down.
Partnerships, affiliates & JVs
ALSO CALLED: Collab
Any project where two or more creators work together, such as a joint video, a guest post, a shared product, or a live event. Agree up front on who does what, who owns the finished work, and how any money is handled.
Design, branding & visuals
ALSO CALLED: color scheme, brand colors
The small, set group of colors you use across your brand and designs, usually a couple of main colors, a neutral or two, and an accent. A limited palette makes everything look like it belongs together.
Digital products & publishing
Permission to use something you bought, such as fonts, clip art, or templates, inside products you sell. Without it, you may only be allowed personal use. Terms vary a lot between sellers, so read exactly what is and is not allowed before you build with it.
Example A clip art license that allows use in printables you sell but not resale of the images on their own.
Money, legal & tax basics
Mixing business and personal money in the same account or paying for personal things with business funds. It makes bookkeeping messy and, for an LLC or corporation, can weaken the legal separation that protects your personal assets.
Example Paying for groceries with the business debit card, then trying to sort it out at tax time.
Partnerships, affiliates & JVs
The payment an affiliate or partner earns for a sale they helped make, usually a percentage of the sale or a flat amount per sale. Find out whether it is figured before or after payment fees, refunds, and taxes, since that changes what you actually receive.
Partnerships, affiliates & JVs
ALSO CALLED: Holding period, Pending period
A waiting period before an affiliate commission is approved for payout, usually long enough to cover the product's refund window. Commissions show as pending until the hold passes, which is why your first payment can take a while to arrive.
Studying the other people and products serving your audience: what they offer, what they charge, what buyers praise and what they complain about. The goal is not to copy but to find gaps you can fill and ways to stand apart.
Example Reading the one-star reviews of competing planners showed me people wanted a simpler version.
Design, branding & visuals
ALSO CALLED: image compression, optimizing images
Shrinking an image's file size so it loads faster, either by removing data you will not notice or by packing it more efficiently. Large, uncompressed photos are one of the most common reasons beginner websites feel slow.
Watch out Compress too hard and photos get blurry or blotchy; check the result before you upload.
Video, audio & podcasting
A sensitive microphone that picks up lots of detail, including the room, the fridge and the neighbor's dog. It sounds rich in a quiet, treated room and noisy in a loud one. Many condenser mics need extra power from an audio interface, called phantom power.
ALSO CALLED: opt-in confirmation, verification email
The email sent right after someone signs up, asking them to click a link to confirm they really want your emails. It is the core of double opt-in and protects you from fake signups and typos.
Example "Please confirm your subscription to The Detention Slip" with a single button.
ALSO CALLED: editorial calendar
A schedule of what you plan to publish and when, across your blog, newsletter, or social accounts. It keeps you from staring at a blank screen on publishing day and helps you space out topics instead of repeating yourself.
ALSO CALLED: content theme
One of a few core topics your content keeps coming back to. Picking three to five pillars keeps your blog or channel focused, so people and search engines know what you are about instead of seeing a random mix.
Example A Gen X lifestyle blog might use pillars like nostalgia, money after 50, and caring for aging parents.
How much text an AI model can keep in view at once, including your messages, any files you share, and its own replies. Once a conversation runs past that limit, earlier details start dropping out, which is why long chats sometimes seem to forget things.
Example A whole book manuscript may not fit in the context window, so you work chapter by chapter.
Money, legal & tax basics
A legally binding agreement between two or more parties about what each will do. A written contract spells out the work, payment, deadlines and what happens if something goes wrong. Plain-language contracts are fine; vague ones cause fights.
Example A short contract with a client that lists the pages you will build, the payment schedule and how many revisions are included.
Design, branding & visuals
The difference between two colors or elements, especially text and its background. High contrast makes text easy to read and helps important things stand out. Light gray text on white might look sleek but is hard for many people to read.
When someone takes the specific action you were hoping for, such as joining your email list, buying a product or booking a call. Each step in a funnel has its own conversion, and a page or message is judged by whether people actually take that step.
Example A visitor who signs up for your free checklist is a conversion on that page.
The percentage of people who took a desired action out of everyone who had the chance. It is found by dividing conversions by visitors or recipients. It is one of the most useful numbers for judging a sales page or signup form.
Example If 200 people visit your sales page and 4 buy, your conversion rate on that page is 2 percent.
Watch out Anyone promising a specific conversion rate for your product is guessing. Rates vary hugely by audience, offer and traffic source.
Setting up your tools so they record when a conversion happens and, ideally, where that person came from. Without it, your ad platform or analytics tool cannot tell you which efforts produced sales.
Partnerships, affiliates & JVs
In affiliate marketing, a small file saved in a visitor's browser when they click your link, so the merchant can credit you if they buy later. Privacy settings and ad blockers can stop it from working, so affiliate tracking is never perfect.
Partnerships, affiliates & JVs
ALSO CALLED: Cookie window, Tracking window
How long after a click an affiliate still gets credit for a purchase. If the buyer comes back and purchases after the window closes, the sale is not credited to you. Programs set their own durations, and they can change them.
Example With a 30-day cookie, a buyer who clicks today and buys three weeks later still counts.
Partnerships, affiliates & JVs
A shady trick where someone secretly drops affiliate cookies on visitors who never clicked a link, to steal credit for sales they did not earn. It violates nearly every affiliate agreement and gets people banned from programs and networks.
Watch out Any "secret" affiliate method that earns commissions without real clicks from real people is likely fraud.
Money, legal & tax basics
Legal protection for original creative work, such as writing, images, music, video and code, once it is fixed in a form like a file or paper. In the US, protection generally exists automatically when you create the work. It does not protect ideas, names or short phrases.
Watch out Finding something on the internet does not mean you can use it. Most images, fonts and text online are owned by someone.
ALSO CALLED: copy, sales copy
Writing meant to get a reader to take an action, such as buying, signing up or clicking. Sales pages, emails, ads and product descriptions are all copy. Good copy is clear and specific about who it is for and what it does.
Watch out Copy that leans on invented urgency, fake results or pressure may work once, but it burns trust and can break advertising rules.
A ticking clock on a sales page or email showing time left to buy at a price or with a bonus. Honest timers mark a real deadline that actually ends. Fake ones reset every time you reload the page or quietly restart for each new visitor.
Watch out Reload the page or check back later; if the timer resets, the deadline was not real.
Selling, ecommerce & payments
ALSO CALLED: Promo code, Discount code
A word or string of characters a buyer types at checkout to get a discount. Codes let you reward your email list, run a limited sale, or track which promotion brought in a sale.
Example Readers of your newsletter get a code called SLIP10 for a discount on your new planner.
Watch out Coupon code browser extensions and code-sharing sites can spread your private codes. Give codes an end date or a usage limit.
Digital products & publishing
A service that hosts an online course for you, handling video lessons, downloads, quizzes, student logins, and often payments. It saves you from building all of that yourself, but your course lives under their rules, so keep your own copies of everything.
ALSO CALLED: Cost per action
Cost per acquisition. The average amount you spend on advertising to get one conversion, such as a sale or signup. It is figured by dividing ad spend by the number of conversions.
Websites, domains & hosting
ALSO CALLED: hosting control panel
A widely used control panel that many web hosts give you for managing your hosting account. From it you can set up email addresses, manage files, create databases, add domains, and install software. Other hosts have their own panels that do similar jobs.
Cost per click. What you pay, on average, each time someone clicks your ad. It is figured by dividing ad spend by clicks. Cheap clicks are useless if none of those people convert.
Cost per mille, meaning cost per thousand impressions. What you pay for your ad to be shown a thousand times, whether or not anyone clicks. Common for ads aimed at awareness rather than direct sales.
ALSO CALLED: spider, bot, search engine bot
An automated program a search engine sends out to visit web pages, read them, and follow their links to find more pages. If a crawler cannot reach a page, that page cannot show up in search results.
ALSO CALLED: content creator
A person who regularly makes and shares content, such as videos, posts, podcasts or newsletters, often building an audience around a topic or personality. Many creators earn through products, sponsorships or affiliate links rather than the platform itself.
An attack where criminals take usernames and passwords leaked from one site and try them on many other sites automatically. It works because people reuse passwords. Using a different password for every account makes this attack useless against you.
Sharing the same piece of content on more than one platform. It saves time, but each platform has its own formats, lengths and culture, so a small adjustment for each one usually works better than a straight copy.
Watch out Some platforms may show fewer people a video that still carries another app's watermark.
Partnerships, affiliates & JVs
ALSO CALLED: Cross-promo
Two creators or businesses promoting each other to their audiences, often with no money changing hands at all. It is one of the simplest partnerships to start with, as long as both audiences actually overlap and each side follows through.
Example You mention a friend's newsletter in yours, and they mention yours the same week.
Selling, ecommerce & payments
Suggesting a related product alongside the one someone is buying or has bought. Done well, it helps buyers find things they actually need. Done badly, it feels like being pestered at the register.
Example Someone buys your recipe ebook, and the thank-you page mentions your printable grocery list.
Websites, domains & hosting
ALSO CALLED: Cascading Style Sheets, stylesheet
Cascading Style Sheets. The code that controls how a web page looks: colors, fonts, spacing, and layout. HTML says what is on the page; CSS says how it should appear. Many site builders let you add small bits of custom CSS.
ALSO CALLED: call to action
Call to action. The specific instruction that tells a reader what to do next, like "Download the checklist" or "Buy the planner." Every page, email or post that has a goal should have one clear CTA, because people rarely take a step they were not asked to take.
Example The button at the bottom of the sales page that says "Get the binder" is the CTA.
Click-through rate. The percentage of people who clicked a link out of those who saw it, found by dividing clicks by impressions or recipients. It shows how well a headline, ad, thumbnail or email link grabs interest.
Example An email sent to 500 people gets 25 clicks on your link, for a click-through rate of 5 percent.
Websites, domains & hosting
ALSO CALLED: domain email, branded email
An email address that uses your own domain name, like hello@yoursite.com, instead of a free webmail address. It looks more professional and stays yours even if you change email providers.
Standing directions you give a chat tool once, which it then applies to every conversation, such as your tone, audience, or preferred format. They save you from retyping the same setup and keep the outputs more consistent from one chat to the next.
Example "Write in plain English for Gen X readers. No hype, no emojis."
ALSO CALLED: buyer's journey
The full path a person takes from first hearing about you to buying and, ideally, coming back or recommending you. Mapping it helps you see where people get confused, lose interest or need more information before they move to the next step.
Video, audio & podcasting
The point where one clip ends and the next begins, or the act of removing a section of footage. Editing is mostly making good cuts: trimming dead air, mistakes and rambling. A tight video is usually a heavily cut video, even when it looks casual.
