Open Rate
Open Rate is the percentage of email recipients who open your email. If you send to 1,000 people and 250 open it, your open rate is 25%. Industry averages range from 15 to 25%. Subject lines drive open rates more than anything else. A compelling subject line can double your open rate overnight. Note: Apple's Mail Privacy Protection inflates open rates for Apple users, so take these numbers with a grain of salt.

Organic Traffic
Visitors who find your website through unpaid search results. They Googled something, your page appeared, they clicked. No ad spend involved. Organic traffic is the result of SEO work: optimizing your site, creating content, building authority. It's the most valuable traffic type because it's free and ongoing. Unlike paid traffic, organic traffic keeps coming even after you stop actively working on it.
Paid Traffic
Visitors who come to your website through paid advertising. Google Ads, Meta Ads, LinkedIn Ads, display networks. You pay for each click or impression. The advantage is speed: you can drive traffic today. The disadvantage is cost: it stops the moment you stop paying. Smart businesses use paid traffic to generate revenue while building organic traffic for the long term.
A/B Testing
Showing two versions of something to different audiences to see which performs better. Version A might have a blue button, Version B a green one. You split traffic 50/50 and measure which version gets more clicks. The winner becomes the new default. This removes guesswork from marketing decisions and lets data drive improvements. Even small changes can produce significant results when tested properly.
Landing Page
A standalone web page created for a specific marketing campaign. Unlike your homepage (which tries to serve everyone), a landing page has one goal and removes all distractions. No navigation menu, no sidebar, no links to your blog. Just a headline, a value proposition, social proof, and a conversion form. Good landing pages convert 5 to 15% of visitors. Bad homepages convert 1 to 2%.
Click-Through Rate (CTR)
The percentage of people who click on your link, ad, or email after seeing it. If 100 people see your ad and 3 click it, your CTR is 3%. Higher CTR means your message resonates with your audience. Low CTR means something needs to change: the headline, the image, the targeting, or the offer itself. Average CTRs vary wildly by platform and industry.
