SEO Abbreviation Explained
Still confused on certain short-form words in the SEO context? Fret not, here are the meanings and explanations of the terms:
1. SERP (Search Engine Results Page)
SERP stands for Search Engine Results Page which is the page users see after entering a search query. It includes a mix of organic results, paid ads, featured snippets, and more. Higher positions on the SERP usually get more clicks, which makes ranking well essential for visibility.
Example
A Google search for “best digital marketing agency Malaysia” may show ads at the top, followed by organic listings and a map pack of local agencies.
2. CTR (Click-Through Rate)
CTR is Click-Through Rate and it indicates how often users click on your link after seeing it in search results. CTR ultimately reflects the strength of your title and meta description in driving engagement.
Example
CTR is calculated using the formula (Clicks ÷ Impressions) × 100.
If your page appears 1,000 times (impressions) and receives 50 clicks, the CTR would be (50 ÷ 1,000) × 100 = 5%.
3. DA (Domain Authority)
Domain Authority reflects the perceived strength of your website in search rankings. It’s a comparative metric, not an official Google signal, but it helps estimate how likely your site is to outrank others. The score ranges between 1 and 100, and the higher it is, the more competitive your domain tends to be.
Example
An established news portal might have a DA of 85, while a small business site may start around 15.
4. CTA (Call to Action)
A CTA guides your visitors toward the next step—clicking a link, filling out a form, subscribing, or making a purchase. It turns passive readers into active participants. Common CTAs include buttons or links like “Subscribe Now,” “Request a Demo,” or “Contact Us.”
Example
At the end of a blog on healthy recipes, a button saying “Download Your Free Meal Plan” clearly directs users to the next step.
5. ALT (Alternative Text)
Search engines can’t see images the way humans do. ALT text facilitates by describing what an image shows so search engines and screen readers can understand its content. It supports accessibility and helps improve image SEO by adding context and relevance.
Example
alt=”Stainless steel water bottle on a wooden table” gives clarity and keyword value.

6. URL (Uniform Resource Locator)
A clear URL helps search engines interpret your page content and gives users a better idea of what to expect. It’s also easier to share, read, and remember. Well-structured URLs contribute to user experience and crawlability.
Example
example.com/seo-tips is more effective than something like
example.com/page?id=12345&ref=abc.
7. HTML (HyperText Markup Language)
HTML forms the core structure of your website. It organises your content so search engines can properly read, index, and rank your pages. Clean HTML supports better SEO by making your site easier to understand for users and crawlers.
Example:
Key SEO-related elements include <title>, <meta>, <h1> to <h6>, and <a>—each helping define the page’s purpose and hierarchy.
8. HTTP (Hypertext Transfer Protocol)
When browsing websites, HTTP handles the exchange of information between your browser and the website’s server, enabling pages to load seamlessly. The secure variant, HTTPS, encrypts this data to safeguard privacy and security, positively influencing SEO.
Example
Sites using HTTPS appear with a secure lock icon (🔒) in browsers, while HTTP sites may display as “Not Secure.”
9. KPI (Key Performance Indicator)
KPIs help measure the success and effectiveness of your SEO strategy. Tracking these metrics regularly allows you to pinpoint what’s working, what’s not, and adjust your strategy for better results.
Example of Common SEO KPIs
Organic traffic, bounce rate, keyword rankings, conversion rate, session duration.
