Search Engine Optimization (SEO) can seem overwhelming at first, especially with the numerous technical terms used in the field. Understanding these SEO terms is crucial for beginners looking to improve their website’s performance.
In this guide, we break down common SEO terms and provide easy-to-understand definitions, along with photos and tips to clarify each concept.
Let’s dive in and simplify the world of SEO!
1. Search Engine Optimization (SEO)
SEO stands for Search Engine Optimization. It’s the process of optimizing your website to rank higher in search engines like Google, Bing, or Yahoo. This includes improving both on-page elements (content, meta tags) and off-page factors (backlinks, social signals) to increase organic traffic.
- Tip: An effective SEO strategy includes keyword research, content optimization, and ongoing performance analysis to improve search rankings.
According to Brigthedge, 53% of all trackable website traffic comes from organic search. SEO is a long-term strategy. It’s about creating high-quality, relevant content that meets search engine guidelines, rather than short-term tricks.
2. Keyword
A keyword is a specific word or phrase that users enter into search engines to find content. In SEO, optimizing your site’s content for relevant keywords helps attract targeted traffic. Keywords can be short (e.g., “SEO terms, SEO search terms”) or long-tail (e.g., “seo terms and definitions for beginners”).
Pro Tip: Choose keywords based on user intent. Use tools like Google Keyword Planner to find high-volume, low-competition keywords.
*According to Ahrefs, the average #1 ranking page also ranks in the top 10 for nearly 1,000 other relevant keywords.
3. On-Page SEO
On-page SEO refers to the optimization of individual pages on your site to rank higher in search results. This includes optimizing meta titles, headers, URLs, and content. The goal is to make your pages more relevant to specific keywords and more user-friendly.
Focus on user experience as well. Fast loading times, mobile-friendliness, and easy navigation contribute to better on-page SEO.
Tip: Improving on-page SEO by optimizing your page titles and including keywords in headings can help your content rank better.
4. Off-Page SEO
Off-page SEO involves activities outside your website that influence your rankings in search results. The most common off-page SEO tactic is backlink building, where other websites link to yours. Social media marketing and influencer outreach also play a role.
Quality matters more than quantity when it comes to backlinks. Focus on earning links from high-authority, relevant sites.
5. Technical SEO
Technical SEO refers to optimizing the technical aspects of your website to improve its visibility and performance in search engines. This includes things like website speed, mobile-friendliness, site architecture, and crawlability.
Based on the data from Search Engine Journal, 51% of companies say that technical SEO issues such as mobile usability or page speed significantly impact their SEO performance.
Tip: Use tools like Google PageSpeed Insights and GTmetrix to test your site’s speed and optimize technical performance regularly.
By improving technical SEO elements like page load speed and fixing crawl errors, your site will be more accessible to both users and search engine bots.”
6. Backlink
A backlink is a hyperlink on one website that points to another website. In SEO, backlinks are considered votes of confidence for your site. The more quality backlinks you have, the more authoritative search engines consider your content.
Tip: Focus on earning natural backlinks by creating valuable, shareable content. Acquiring backlinks from well-established sites in your industry can boost your site’s domain authority and help you rank higher.
The top Google results have an average of 3.8 times more backlinks than results ranked 2-10 according to Ahrefs.
7. SERP (Search Engine Results Page)
The SERP is the page displayed by a search engine in response to a user’s query. It typically includes a mix of organic results, paid ads, featured snippets, and other search features like image carousels.
Above photo is an example of the Search Engine Results Page for the keyword “basketball shoes 2024”.
Aim for the first page of results (especially the top 3 positions), as these get the majority of clicks.
8. Organic Traffic
Organic traffic refers to visitors who land on your website from unpaid (non-advertising) search engine results. It is one of the most valuable forms of traffic, as it reflects a user’s genuine interest in your content or product.
Continuously improve content quality and SEO practices to increase organic traffic over time.
9. Meta Tags
Meta tags are snippets of HTML code that provide metadata about a webpage. The most important meta tags for SEO include the meta title and meta description, which appear in the SERP and influence click-through rates.
Keep the meta title under 60 characters and meta descriptions under 160 characters and include your target keyword.
Optimizing your meta tags with targeted keywords can help search engines understand your page content and improve your rankings.
10. Alt Text
Alt text (or alternative text) is an HTML attribute added to images that describes what the image is about. Search engines rely on this text to understand images, and it also helps with accessibility for users who use screen readers.
- Tip: Use clear, descriptive alt text that includes your keywords where appropriate, without keyword stuffing.
Including accurate alt text like the example on the photo helps search engines understand your images better and boosts your image SEO.
11. Anchor Text
Anchor text is the clickable, visible text in a hyperlink. In SEO, anchor text should be relevant to the page you are linking to and help users understand the context of the link.
Avoid generic anchor text like “click here.” Use descriptive phrases like the example in the photo instead to improve SEO and usability.
12. Crawling
Crawling is the process search engines use to discover new or updated content on the web. Search engine bots (crawlers) scan websites and follow links to index new pages or changes in existing ones.
Ensure your website is crawlable by fixing broken links, using clean URLs, and maintaining an updated sitemap.
13. Indexing
Indexing is when a search engine stores information from a webpage after crawling it. Pages in the index can then appear in search results when relevant queries are entered.
Ensure important pages are indexed by submitting them through Google Search Console and regularly monitoring your index coverage.
After submitting your sitemap, Google will start indexing your website, allowing it to appear in search results.”
14. Keyword Density
Keyword density is the ratio of how often a keyword appears in your content compared to the total word count. While keyword use is important, overuse (keyword stuffing) can result in penalties.
Aim for natural keyword usage, ensuring your content is helpful and reads smoothly without forcing keywords.
Google recommends focusing on keyword relevance rather than keyword density. Over 1.5% keyword density may be considered “keyword stuffing” (according to Moz), so maintain a balanced keyword density to ensure your content is optimized for search engines but remains easy for readers to follow.”
15. Long-Tail Keywords
Long-tail keywords are longer, more specific search phrases (usually 3+ words) with lower search volumes but higher conversion rates. They are often less competitive and more targeted.
Example: Optimizing for long-tail keywords like ‘best running shoes for flat feet’ helps your site rank for more specific, lower-competition searches.
Pro tip: Use long-tail keywords to attract highly targeted traffic. These keywords often indicate purchase intent or specific questions.
16. Domain Authority (DA)
Domain Authority (DA) is a metric developed by Moz that predicts how well a website will rank on search engines. Scores range from 1 to 100, with higher scores indicating greater likelihood of ranking.
Focus on improving content quality, earning backlinks, and enhancing your site’s overall structure to gradually increase your DA.
Increasing DA is a long-term process, typically taking 6-12 months of sustained effort.
17. Bounce Rate
Bounce rate is the percentage of visitors who leave your website after viewing only one page, without interacting further. A high bounce rate may indicate that your content isn’t engaging or relevant and visitors aren’t finding what they’re looking for, which could hurt your site’s SEO performance.
Lower your bounce rate by creating engaging content, improving site navigation, and making sure your pages load quickly.
18. Click-Through Rate (CTR)
CTR is the percentage of users who click on your link after seeing it in search results. A higher CTR usually indicates that your meta tags are compelling and relevant to the user’s query.
A low click-through rate can indicate that your meta descriptions and titles aren’t attracting enough attention in the SERPs.
Pro Tip: Improve your CTR by crafting engaging titles and meta descriptions that include your target keywords.
19. Canonical URL
A canonical URL is the preferred version of a web page that search engines should index. This is especially useful when you have duplicate content, as it prevents search engines from penalizing your site.
Always use a canonical URL when you have multiple versions of the same page, such as for different languages or mobile versions.
20. Robots.txt
Robots.txt is a file located in the root directory of your website that tells search engine crawlers which pages or files they are allowed (or disallowed) to index.
You can check the robots.txt of the website by entering the website URL then adding the “robots.txt” (e.g. https://yourwebsite.com/robots.txt)
Note: Be cautious when using robots.txt; blocking too many pages could prevent important content from being indexed.
21. Sitemap
A sitemap is a list of all the pages on your website, typically created in XML format, that helps search engines understand your site structure and index your content more effectively.
Pro tip: Keep your sitemap updated as you add new content. Submit it to Google Search Console to ensure efficient indexing.
22. Schema Markup
Schema markup is a form of structured data that helps search engines understand your content better and can result in enhanced search results (like rich snippets).
Use schema for products, reviews, events, and other relevant content to improve your visibility in search results.
Less than 30% of websites currently implement schema markup, providing a competitive advantage. (Search Engine Land)
23. Title Tag
A title tag is an HTML element that defines the title of a webpage. It appears in the SERP and plays a crucial role in determining both your search rankings and your CTR.
- Tip: Include your target keywords in the title tag and keep it under 60 characters to avoid truncation in the SERP.
24. XML Sitemap
An XML sitemap is a specific type of sitemap file that lists all of the URLs on your website, helping search engines crawl and index your site more efficiently.
Websites with regularly updated XML sitemaps are indexed faster, resulting in better ranking potential.
