Search Engine Optimisation (SEO) is a core component of any successful digital marketing strategy. It helps improve a website’s visibility in search engine results, which can lead to more traffic and ultimately more conversions. While SEO may seem overwhelming at first, understanding the basic terms and principles can significantly simplify the process. In this post, we’ll cover essential SEO terms in detail, and provide practical, easy-to-follow steps for using these strategies to improve your website’s performance.
Whether you’re a blogger, an e-commerce store owner, or a corporate site manager, mastering these SEO terms will provide you with a strong foundation for growing your organic search traffic.
1. Anchor Text
Definition:
Anchor text is the clickable text within a hyperlink that leads to another page, either on the same website (internal linking) or on a different site (external linking). It’s typically underlined or appears in a different colour to distinguish it from regular text.
Why It Matters:
Search engines use anchor text to understand the content of the page that the link points to. Well-optimised anchor text can help improve the relevance of the page for specific search queries, which can boost its ranking in search results.
How to Implement It:
- Choose relevant keywords: The anchor text should be a natural fit for the linked page. If you’re linking to a page about “SEO tips,” use those words in the anchor text.
- Avoid over-optimisation: Repeating the exact same anchor text too often can trigger penalties from search engines. Instead, vary your anchor text while still using relevant keywords.
- Keep it concise: Aim for 2-5 words in your anchor text. Phrases like “click here” or “read more” don’t provide any context and should be avoided.
Example:
If you’re linking to a guide on “keyword research,” a good anchor text could be: “Learn effective keyword research strategies.” This provides both context and keywords in a natural way.
Tip: Don’t overuse keyword-rich anchor text. Varying your anchor text by using synonyms or more descriptive phrases will make your content look more natural to search engines.
2. Alt Text (Alternative Text)
Definition:
Alt text is a short description of an image that helps search engines and visually impaired users understand what the image is about. It’s an HTML attribute that you add to image tags in your website’s code.
Why It Matters:
Since search engines can’t “see” images the way humans can, they rely on alt text to understand and index image content. Alt text also plays a crucial role in improving accessibility for visually impaired users, as screen readers use alt text to describe images.
How to Implement It:
- Always add alt text to your images, especially those that add important context to the content.
- Describe the image clearly: Write alt text that accurately describes the image in a concise manner.
- Incorporate relevant keywords naturally, but don’t stuff them in. The priority is to provide a meaningful description of the image.
Example:
For an image showing a person working on SEO, instead of simply writing “person at a desk,” you could use: “SEO specialist optimising a website using keyword research tools.”
Tip: Use alt text for every image on your site, especially for images that are integral to the content. However, avoid keyword stuffing in the alt text—focus on describing the image naturally.
3. Authority
Definition:
In SEO, authority refers to the level of trust a website has in the eyes of search engines. A site with high authority is viewed as a trustworthy source of information and is more likely to rank higher in search results.
Why It Matters:
Authority is a key factor in how search engines rank websites. Websites with high authority are more likely to show up in top search results for relevant keywords. Authority is built through a combination of factors, including backlinks from reputable websites, high-quality content, and good user experience.
How to Build Authority:
- Publish high-quality content that answers users’ questions and provides valuable insights.
- Earn backlinks from authoritative websites. The more reputable sites that link to your content, the more search engines will trust your site.
- Improve user experience by ensuring your site is easy to navigate, fast to load, and mobile-friendly.
Example:
If you run a health blog and authoritative sites like the NHS or WebMD link to your articles, this can significantly boost your site’s authority, leading to better rankings for related keywords.
Tip: Authority is built over time, so focus on producing consistent, high-quality content and building genuine relationships with other websites in your niche.
4. Bots (Crawlers or Spiders)
Definition:
Search engine bots, also known as crawlers or spiders, are automated programs that “crawl” through web pages to gather information. They index content, follow links, and help search engines understand what your website is about.
Why It Matters:
If your website isn’t crawlable, it won’t appear in search results. Search engine bots must be able to access your site, navigate through it, and index its content to display it in search results.
How to Optimise for Bots:
- Submit a sitemap to Google Search Console so crawlers can easily find all of your pages.
- Use internal linking to help bots navigate your website. Linking related pages to one another makes it easier for crawlers to find and index your content.
- Fix broken links and ensure there are no barriers (like blocked pages or login requirements) that prevent bots from crawling your site.
Example:
Using tools like Screaming Frog or Google Search Console, you can identify pages that bots may have trouble crawling, and fix any issues like broken links or inaccessible pages.
Tip: Make sure your website is free from errors, has a clear structure, and uses internal links to ensure that crawlers can fully index all of your content.
5. Title Tag
Definition:
A title tag is an HTML element that defines the title of a webpage. This is the clickable headline that appears in search engine results and at the top of the browser window.
Why It Matters:
Title tags are one of the most important on-page SEO elements. They provide both search engines and users with a clear understanding of the page’s content, and a well-optimised title tag can improve both rankings and click-through rates.
How to Write an Effective Title Tag:
- Include your primary keyword near the start of the title tag.
- Keep it concise, typically under 60 characters, to ensure the entire title is visible in search results.
- Make it compelling: Use action-oriented words or questions to encourage clicks.
Example:
For a page about SEO basics, a good title tag might be: “SEO Basics: How to Improve Your Website’s Ranking in 2024.” This title is clear, concise, and includes relevant keywords.
Tip: Use tools like Moz or Yoast SEO to preview how your title tag will appear in search results and to ensure it’s not too long.
6. Meta Description
Definition:
A meta description is a brief summary of a webpage’s content that appears in search engine results under the title tag. While it doesn’t directly affect rankings, a well-crafted meta description can improve click-through rates.
Why It Matters:
A compelling meta description helps users understand what your page is about and encourages them to click through to your site. It’s a key element in attracting visitors from search results.
How to Write a Meta Description:
- Summarise the page’s content in 150-160 characters.
- Include a call to action if possible, such as “Learn more” or “Find out how.”
- Use relevant keywords, but focus on clarity and engagement over keyword stuffing.
Example:
For a blog post on SEO for beginners, a meta description might read: “Learn essential SEO terms and strategies to boost your website’s search engine ranking. Perfect for beginners and experts alike.”
Tip: Don’t forget to check your meta descriptions regularly to ensure they remain relevant as your content evolves.
7. Keywords
Definition:
Keywords are words or phrases that users type into search engines when looking for information. In SEO, keywords are what you optimise your content around to ensure it appears in relevant search results.
Why It Matters:
Using the right keywords ensures your content reaches the right audience. When your content matches user search queries, search engines are more likely to rank your pages highly.
How to Use Keywords Effectively:
- Conduct thorough keyword research using tools like Google Keyword Planner, SEMrush, or Ubersuggest. Focus on keywords with high search volume and manageable competition.
- Place your keywords strategically in key areas of your content, such as the title, headings, and meta descriptions. However, avoid overusing keywords, as this can lead to penalties.
Example:
For a blog about baking, relevant keywords might include “best cupcake recipes” or “easy bread baking tips.”
Tip: Target long-tail keywords (explained below) to attract more specific traffic.
8. Long-Tail Keywords
Definition:
Long-tail keywords are longer, more specific keyword phrases. While they generally have lower search volume than broader keywords, they are often more targeted and have higher conversion rates.
Why It Matters:
Long-tail keywords can be easier to rank for and often attract more qualified visitors—people who are closer to making a purchase or decision.
How to Find Long-Tail Keywords:
- Use tools like AnswerThePublic or Google’s autocomplete feature to find popular long-tail keyword phrases related to your niche.
- Focus on specific questions or detailed queries that users may search for.
Example:
Instead of targeting the broad keyword “SEO,” a long-tail keyword might be “how to improve SEO for small businesses.”
Tip: Write detailed, focused content aimed at answering specific long-tail keyword queries to attract highly targeted traffic.
9. Keyword Density
Definition:
Keyword density refers to the percentage of times a keyword appears on a webpage compared to the total word count. It’s an outdated SEO metric, but maintaining a reasonable keyword density is still important to avoid over-optimisation penalties.
Why It Matters:
While keyword stuffing can lead to penalties, a well-optimised keyword density can help search engines understand the topic of your page without overdoing it.
How to Calculate and Use Keyword Density:
- Formula: Divide the number of times the keyword appears by the total word count, then multiply by 100 to get the percentage.
- Aim for natural usage: Keep keyword density between 1-2%, but focus on natural, user-friendly content rather than meeting a strict percentage.
Example:
For a 1000-word blog post, using your main keyword about 10-15 times is typically enough to avoid overuse while ensuring search engines recognise the topic.
Tip: Use variations and synonyms of your keyword to make your content more natural and engaging.
10. Domain Authority (DA)
Definition:
Domain Authority (DA) is a score developed by Moz that predicts how well a website will rank in search results. The score ranges from 1 to 100, with higher scores indicating a stronger likelihood of ranking well.
Why It Matters:
While Domain Authority isn’t a direct ranking factor used by Google, it’s a useful metric for assessing the overall strength of your website compared to competitors. Higher DA typically correlates with better rankings and more organic traffic.
How to Improve Domain Authority:
- Create valuable, high-quality content that people want to link to.
- Earn backlinks from reputable sites in your industry to boost your DA over time.
- Ensure strong technical SEO by optimising your site’s speed, security, and mobile responsiveness.
Example:
A site with a DA of 80 is far more likely to rank highly than one with a DA of 20, especially for competitive search terms.
Tip: Use tools like Moz’s Domain Authority checker to monitor your site’s DA and track improvements over time.
11. Page Authority (PA)
Definition:
Page Authority (PA) is similar to Domain Authority but focuses on the ranking potential of a specific page rather than an entire website.
Why It Matters:
Even if your website has a high DA, individual pages might still need attention. Improving the PA of key pages can help them rank better in search results.
How to Improve Page Authority:
- Earn high-quality backlinks for the specific page.
- Use internal links from other high-authority pages on your site to pass authority to the target page.
Example:
If you have a blog post that consistently drives traffic, you can improve its Page Authority by earning more backlinks and linking to it from other pages on your site.
Tip: Focus on building authority for the pages that matter most to your business, such as product or service pages.
12. Backlinks
Definition:
Backlinks are links from other websites that point to your website. They are one of the most important ranking factors in SEO, as search engines view backlinks as a vote of confidence in your content.
Why It Matters:
Backlinks from high-authority websites can significantly boost your website’s authority and improve its rankings. However, not all backlinks are created equal—links from low-quality or irrelevant sites can harm your SEO.
How to Earn Backlinks:
- Create shareable content like infographics, research studies, or helpful guides.
- Guest post on reputable websites in your niche to build links back to your site.
Example:
If a popular food blogger links to your recipe website, this can improve your rankings and drive traffic to your site.
Tip: Regularly monitor your backlink profile using tools like Ahrefs or Moz to ensure your links are high quality and avoid any harmful links.
13. 301 Redirect
Definition:
A 301 redirect is a permanent redirection from one URL to another. It tells search engines and users that the page has permanently moved, and any link equity (SEO value) from the old URL should be passed to the new one.
Why It Matters:
301 redirects ensure that users and search engines are directed to the correct page if a URL changes. This preserves your SEO rankings and prevents users from landing on broken pages.
How to Use 301 Redirects:
- Use when changing URLs: If you update a page’s URL, set up a 301 redirect from the old URL to the new one.
- Use for page deletions: If you remove a page, redirect it to a relevant alternative page to avoid 404 errors.
Example:
If you rename a blog post from “2023 SEO tips” to “2024 SEO tips,” use a 301 redirect to send traffic from the old URL to the updated version.
Tip: Use tools like Screaming Frog or Google Search Console to monitor for broken links and set up redirects as needed.
14. Canonical URL
Definition:
A canonical URL is the preferred version of a webpage when there are multiple URLs with similar content. The canonical tag helps prevent duplicate content issues by telling search engines which page to prioritise.
Why It Matters:
Duplicate content can confuse search engines and dilute your SEO efforts. Using canonical tags ensures that search engines index the right version of your page.
How to Use Canonical URLs:
- Apply canonical tags to pages with similar or identical content.
- Point to the main version of the page to consolidate link equity and avoid duplicate content penalties.
Example:
If you have several product pages that vary slightly based on filters or parameters, use a canonical tag to point to the main product page.
Tip: Regularly review your site for duplicate content and apply canonical tags where necessary.
15. Internal Linking
Definition:
Internal linking refers to links that point from one page on your website to another. These links help search engines and users navigate your site and distribute ranking power across your pages.
Why It Matters:
Internal linking is crucial for SEO because it helps search engines understand the structure of your website and pass authority between pages. It also improves user experience by guiding visitors to related content.
How to Implement Internal Linking:
- Link to relevant pages: Whenever you mention a topic that’s covered in more detail on another page, link to it.
- Use descriptive anchor text to help users and search engines understand the context of the link.
Example:
If you mention “on-page SEO” in a blog post, you could link to another article that provides a deeper explanation of that concept.
Tip: Ensure that your most important pages (such as service pages) are receiving plenty of internal links from other pages on your site.
16. Sitemap
Definition:
A sitemap is a file that lists all the important pages on your website. It helps search engines crawl and index your site more efficiently.
Why It Matters:
Sitemaps make it easier for search engine bots to find and index your content. This is especially important for large websites or those with complex navigation.
How to Create a Sitemap:
- Use a plugin: If you’re using WordPress, plugins like Yoast SEO or All in One SEO Pack can generate a sitemap automatically.
- Submit your sitemap to Google Search Console to ensure it’s indexed.
Tip: Review your sitemap regularly, especially when adding new content or restructuring your site.
17. Headings (H1 to H6)
Definition:
Headings are HTML elements (H1 through H6) that structure content on a webpage. The H1 tag is usually reserved for the main title, while H2 and lower headings are used for subheadings.
Why It Matters:
Headings improve both user experience and SEO by helping search engines understand the structure and hierarchy of your content. Proper use of headings also makes content easier to read and navigate.
How to Use Headings Effectively:
- Use one H1 tag per page, usually for the title of the page.
- Use H2 and H3 tags to break up content into logical sections. Incorporate secondary keywords naturally in these headings.
Example:
For a blog post titled “SEO Basics,” your H1 could be: “SEO Basics for Beginners,“ and an H2 might be: “How to Choose the Right Keywords.”
Tip: Tools like Yoast SEO can help ensure your headings are structured correctly and optimised for search engines.
