CAC is what you spend on sales and marketing to win one new customer. If you spent $300,000 on sales and marketing last quarter and won 60 customers, your CAC is $5,000. Compare it with LTV and payback period to see whether growth is healthy.
CAC payback period is how many months of a new customer's gross profit it takes to cover what you spent to win them. With a $6,000 CAC and a customer paying $1,000 a month at 80% gross margin, payback takes 7.5 months.
A call to action is the button or line that tells the reader what to do next, like "Book a demo", "Start free trial" or "Get the template". The best CTAs match where the reader is, so a pricing page asks for a demo while a beginner guide offers a checklist.
A canonical tag is a line of code in a page's head that tells search engines which URL is the main version when several URLs show the same content. If your pricing page loads at /pricing and at /pricing?ref=nav, the canonical tag on both points to /pricing.
Churn is the customers or revenue you lose when people cancel or don't renew. If you start the month with 500 customers and 10 cancel, your monthly logo churn is 2%. Revenue churn counts lost dollars, which matters more when your customers vary a lot in size.
A content brief is the plan a writer gets before writing: the target keyword, the reader, the search intent, the outline, the sources and experts to use and the CTA. A good brief for "SOC 2 compliance checklist" also lists the product features to mention and the questions sales hears most.
Content distribution is everything you do to get a piece in front of people after you publish it, like LinkedIn posts, newsletters, sales emails, communities, paid promotion and partner shares. A benchmark report reaches far more of the right readers when the founder posts the key chart and sales sends it to open deals.
A content engine is a repeatable system for planning, writing, publishing and sharing content every month, with clear owners and steps. For a B2B SaaS team, that might mean four articles and twelve founder posts a month, all planned from the same buyer questions and refreshed when they start to age.
Content marketing is creating useful articles, guides, videos and posts so buyers find you, learn from you and trust you before they talk to sales. For a B2B SaaS company, that might be a guide on cutting cloud costs that brings in engineers who later try your FinOps tool.
A content pillar is one of the three or four main themes a person or brand keeps posting about. The founder of a sales tool might rotate between pipeline math, hiring sales reps and lessons from building the company. Pillars keep posts focused, so people remember what you stand for.
A content refresh is updating a published page so it stays accurate and keeps ranking, with new data, new screenshots, new sections and a fresh look at search intent. A "best CRM for startups" post from last year may already list old prices. Refreshing pages that already rank is often faster than writing new ones.
Conversion rate is the share of people who take the action you want, out of everyone who could. If 2,000 people visit your demo page and 60 book a demo, that page converts at 3%. Track it per page and per channel, because a blog post and a pricing page have very different jobs.
Core Web Vitals are three Google measures of how a page feels to use. Largest Contentful Paint is how fast the main content loads and Interaction to Next Paint is how fast the page reacts to a click. Cumulative Layout Shift is how much things jump around while it loads.
CPC is what you pay each time someone clicks your ad. If you spend $2,000 on a Google Ads campaign for "SOC 2 software" and get 160 clicks, your CPC is $12.50. High CPCs are normal for B2B buying keywords, so judge them by cost per qualified lead and pipeline.
CPL is your ad or campaign spend divided by the leads it brought in. Spend $5,000 on LinkedIn Ads, get 50 form fills, and your CPL is $100. A cheap lead that never books a meeting costs more in the end than a pricier lead who buys.
Crawl budget is how many pages Googlebot can and wants to crawl on your site in a given period. A SaaS site with 300 pages rarely needs to think about it. A docs site whose filters spin out 80,000 URLs does.
