What Is SEO? (Search Engine Optimization)

SEO is the process of optimizing your website so it ranks higher on Google. The better your SEO, the more free, organic traffic you get. Simple.

Core SEO Terms You Need to Know

1. Algorithm

Google’s secret formula that decides which pages rank where. It looks at hundreds of factors like content quality, backlinks, and user experience.

2. Backlinks

Links from other websites to yours. The more high-quality backlinks you have, the more Google trusts your site.

3. CTR (Click-Through Rate)

The percentage of people who click your link after seeing it in search results. Higher CTR = better rankings.

4. Domain Authority (DA)

A score (0-100) that predicts how well your site will rank. Higher DA = stronger SEO.

5. Keyword

The words people type into Google. Example: "best running shoes for flat feet."

6. Long-Tail Keyword

A more specific, less competitive keyword phrase. Example: "best waterproof running shoes for women with wide feet."

7. Meta Description

The short blurb under your link in search results. Write this well to boost CTR.
