If you want to succeed in SEO, every step—from keyword research to technical SEO, from internal linking to structured data—is crucial. How familiar are you with common SEO terms? This SEO guide will break down 20 key terms and help you master the secrets of improving website rankings!

1. Keyword

A keyword is a word or phrase that users enter into search engines—it’s the core of SEO. Choosing the right keywords helps your website rank higher in search results.

When selecting keywords, you must consider three factors: search volume, competition level, and relevance to your business. Ignoring any of these could affect your SEO results.

2. Keyword Research

Keyword research is the foundation of an SEO strategy, aimed at identifying the exact terms users search for. This helps you understand market demand and gives direction for content creation.

For example, if “coffee” has a high search volume, you might consider creating content around this topic.

Tools like SEMrush and Ubersuggest can provide data on search volume, competition, and related keywords.

3. Long-tail Keywords

Long-tail keywords are longer, more specific keyword phrases with lower search volume but higher accuracy in capturing user intent.

Unlike short-tail (broad) keywords, long-tail keywords may not individually attract high traffic, but their combined volume can be significant and provide stable long-term results.

4. Title Tag

A title tag is an HTML element that defines a webpage’s title. It appears in browser tabs and search results.

A well-optimized title tag should include the primary keyword and be compelling enough to encourage clicks.

5. Meta Description

A meta description is a short summary of a webpage, typically displayed in search results. Its main function is to help search engines and users quickly understand the page’s content.

A good meta description should be concise, include the main keyword, and have a clear call to action to boost click-through rates.

6. Backlinks

A backlink is a link from another website pointing to your site. Search engines use backlinks to determine a site’s authority.

If high-authority websites link to you, it signals to search engines that your content is credible, helping improve your rankings.

7. Internal Links

Internal links connect different pages within your website. They help users navigate easily and allow search engines to index and understand your site structure.

A strong internal linking strategy can enhance user experience, increase time spent on your site, and improve rankings for important pages.

8. Website Architecture

Website architecture refers to how your site’s pages are structured and linked.

A well-organized website improves user experience and makes it easier for search engines to crawl your site.

Best practices include using breadcrumb navigation, clear URL structures, and minimizing the number of clicks needed to reach key pages.

9. Anchor Text

Anchor text is the clickable text in a hyperlink, usually shown in blue with an underline.

SEO-friendly anchor text should be relevant, natural, and descriptive.

Example:

10. Sitemap

A sitemap is a file that lists all pages of a website to help search engines index content efficiently.

For e-commerce websites, a clear sitemap ensures that search engines can quickly find all product pages.

You can submit your sitemap to Google Search Console to ensure proper indexing.

11. Robots.txt

A robots.txt file tells search engines which pages they can or cannot crawl.

For example, if you don’t want search engines to index your admin panel, you can add this to your robots.txt file:

Disallow: /admin/

However, robots.txt cannot completely prevent a page from being indexed.

12. 301 Redirect

A 301 redirect permanently redirects one URL to another, passing SEO value to the new page.

It’s commonly used when changing URLs or merging duplicate content into a single, authoritative page.

13. 404 Error

A 404 error occurs when a user tries to access a non-existent page.

To reduce frustration, you can create a custom 404 page with navigation options or a search bar.

Regularly check for broken links and fix them to minimize 404 errors.

14. Site Speed

Site speed refers to how fast a web page loads. If your site takes longer than 3 seconds, users may leave and visit a competitor instead.

Ways to improve site speed:

●Compress images

●Enable browser caching

●Reduce HTTP requests

●Use Google PageSpeed Insights to analyze and optimize speed.

15. Mobile Friendly

A mobile-friendly website works well on all screen sizes and devices.

A responsive web design automatically adjusts layout and content to fit different screens, ensuring a smooth experience on desktops, tablets, and smartphones.

16. Structured Data

Structured data is a standardized format that helps search engines better understand webpage content.

For example, a recipe website with JSON-LD structured data can have its recipes displayed as rich results in Google Search.

17. Click-Through Rate (CTR)

CTR is the percentage of users who click your website link from search results.

If your page ranks well but has a low CTR, your title and meta description may not be attractive enough, you can choose to Improve them to boost engagement.
