What is an SEO Keyword?: Strategies for Better Rankings

If you want your business or content to be found online, understanding SEO keywords is key. These keywords are specific words or phrases individuals use search engines when seeking information online. When used strategically, these can improve your rankings, attract the right audience and bring in traffic that’s interested in what you offer. 

For example, terms like “best mechanical keyboards” or “budget-friendly travel destinations” can greatly influence your site’s click-through rate. Focus on aligning your website content with these popular search terms to boost visibility and improve rankings.

This guide will help you understand the different aspects of SEO keywords, including the different types, and how to choose and use them effectively to sharpen your SEO strategy and climb the search rankings.

Types of SEO Keywords

SEO keywords link what people are searching for with the content you provide. To craft an effective SEO strategy, it’s important to understand the different types of keywords and their roles in driving traffic.

Short-tail Keywords

Short-tail keywords, often called head terms, are broad and high-volume search phrases typically made up of one or two words, like “laptop.” While these keywords can drive significant traffic, they are also highly competitive, making it challenging to achieve strong rankings, and the conversion rates might be lower. 

While high visitor traffic can be appealing, it doesn’t always translate to alignment with your specific goals. Many visitors might not be searching for your products or services. Also, these keywords are more competitive, making it harder for smaller websites to rank high without significant domain authority and backlinks.

Mid-tail Keywords

Mid-tail keywords area phrases typically consist of two or three words and balance between short-tail and long-tail keywords. They are often more manageable for small or medium-sized websites to rank for, as they are less competitive than short-tail keywords but still offer a decent search volume.

These keywords are more specific to user intent, improving the likelihood of attracting interested traffic to your content or products. For example, a user searching for “gaming laptop” is more likely to result in a conversion than someone searching for a more general keyword, “laptop.”

Long-tail Keywords

Long-tail keywords usually contain four or more words and are highly specific to the user’s search intent. Examples include “gaming laptops under $1000” or “affordable summer vacations in Europe.” While long-tail keywords generally attract lower search volumes than shorter ones, they tend to be far less competitive and frequently yield higher conversion rates.

Long-tail keywords are especially useful for businesses focused on organic traffic because they target people who know exactly what they want.

The Role of SEO Keywords in Online Visibility

SEO keywords connect user queries and your content, helping search engines like Google find and rank your content. When you use the right keywords, you make your content easier to find, connecting you with people searching for your offer. However, it’s not just about inserting keywords— it’s about understanding how search engines interpret them and what search intent they correspond to.

Search Engine Algorithms and Keyword Relevance

Search engines utilise complex algorithms to evaluate the relevance of a website to a specific query. These algorithms consider different factors, such as keyword frequency, placement, and contextual relevance. 

For example, using a keyword naturally in headings, body content, and meta tags helps search engines better understand the content of your page. But it’s not enough to add keywords to your content; they must be relevant to the search query and match the user’s intent.

Search engines evolved to better understand the semantics behind a query. With algorithms like Google’s RankBrain and BERT, search engines can process natural language and discern intent beyond exact keyword matches. This makes it essential to use keywords that align with what users are searching for and why they are searching for it.

Understanding Search Intent

Knowing what users intend to find when they search online is key to selecting the right SEO keywords and crafting content that meets their needs. Search intent generally falls into four categories:

• Informational Intent – The user seeks information, such as answers to questions or how-to guides (e.g., “how to change RAM in laptop”).
• Navigational Intent – The user seeks a particular website or brand. (e.g., “Facebook login”).
• Transactional Intent – The user aims to purchase or complete an action (e.g., “buy gaming laptop online”).
• Commercial Investigation – The user  researching products or services but isn’t ready to purchase yet (e.g., “best laptops for gaming.”

When your content matches with user search intent, it will engage users effectively, reducing bounce rates and increasing conversion rates. This alignment enhances user experience and significantly increases your site’s potential for success by genuinely addressing the needs of your audience.

Methods for discovering effective keywords

Effective keyword research optimises the chances of aligning content with both user intent and business goals. It is more than just coming up with a list of potential terms. Here’s a step-by-step guide to discovering the most effective keywords for your content:

1. Brainstorming Seed Keywords

Start by identifying seed keywords, which are the basic terms relevant to your business or industry. These seed keywords will be the starting point for your keyword research. For instance, if you run a shoe store, seed keywords might include “running shoes,” “athletic footwear,” or “sneakers.” Seed keywords are usually short-tail terms that help you expand into more specific phrases

2. Use keyword research tools.

Keyword research tools are instrumental in identifying, analysing, and selecting the right SEO keywords. Once you have a list of seed keywords, use keyword research tools like Ahrefs, SEMrush, and AnswerThePublic, which offer many features to enhance your keyword research.

• Google Keyword Planner: A feature within Google Ads that provides average monthly search volume data and an understanding of competition for particular keywords. 
• Ahrefs and SEMrush: Offers detailed insights into keyword difficulty, backlink profiles, and competitor analysis. 
• AnswerThePublic: Useful for capturing the questions and prepositions associated with search terms and exploring the mindset and intent of searchers. This can lead to discovering Long-tail keywords that are less competitive and have a higher conversion potential.

When using these tools, analyse the data together to better understand keyword effectiveness. Look for keywords with high search volume and moderate difficulty, indicating a great opportunity for strong rankings. You can create a well-informed and effective keyword strategy by integrating data from various sources.

3. Analysing competitors

Conducting a competitive analysis provides insights and can reveal opportunities to outrank competitors. Evaluate the keywords your competitors rank for and pinpoint gaps where they may have overlooked valuable long-tail keywords.

Key factors to consider in keyword selection

Choosing the right SEO keywords is like selecting the best strategies for a successful business plan. These keywords must align with your goals while engaging enough to attract customers. They signal search engines, helping potential clients find your content. Balancing search volume, keyword difficulty, and relevance is crucial in improving a site’s ranking and user engagement, ultimately driving organic traffic and business growth. Here are some factors to consider: 

Search Volume 

Search volume indicates how often a keyword is searched for in a given period, usually monthly. High-volume keywords are frequently searched, indicating a substantial potential to attract organic traffic. However, they often come with steep competition, meaning many websites are vying for a top spot in search results for these terms.

On the other hand, low-volume keywords tend to be more niche with fewer search queries but can be easier to rank for due to less competition. These can be particularly useful for targeting specific audiences and capturing traffic from more defined search intent.

Prioritise keywords that not only have moderate to high search volumes but also precisely match the subject matter and interests of the target audience to maximise the chances of driving relevant traffic to your content.

Tips for Using Search Volume Data:

• Look beyond numbers; consider the relevance and search intent.
• Balance your keyword strategy with both high-volume terms and niche phrases.
• Ensure alignment with content goals and user interests.

Keyword Difficulty 

This metric estimates how hard it would be to rank for a particular keyword on search engine results pages (SERPs). The calculation of keyword difficulty is typically based on factors such as the level of competition and the domain authority of the websites currently ranking for that term.

Selecting keywords that align with a website’s existing SEO strength is important. A balanced content strategy should incorporate low, medium, and high-difficulty keywords. This can be visualised in the following manner:

• Low-Difficulty Keywords: Quick wins for new websites; less competition.
• Medium-Difficulty Keywords: Progressively challenging, offering sustainable growth.
• High-Difficulty Keywords: Competitive, generally aimed at established websites with strong authority.

Focusing on relevant yet less competitive keywords, especially in the early stages of businesses, can establish their online presence and lay the groundwork for higher rankings on more competitive terms as their website authority increases.

Keyword Density

Keyword density measures how frequently a keyword appears within your content relative to the total word count. Aiming for a keyword density of about 1-2% is a good practice, which means that for every 100 words of content, the keyword should ideally appear once or twice.  Rather than fixating on strict percentages, it’s more important to incorporate your keyword naturally and meaningfully without force-feeding it into every other sentence—a tactic known as keyword stuffing, which can negatively affect your SEO efforts.

Effective SEO is less about hitting a mathematical target and more about crafting engaging, relevant content that answers search queries and satisfies search intent while organically incorporating target keywords.

Context Relevance

Contextual relevance refers to the degree to which a keyword seamlessly integrates with the surrounding content, enhancing the overall theme and satisfying user intent. A thorough contextual analysis will ensure keywords attract not just traffic but the right kind of engaged and satisfied visitors. 

For instance, the keyword “apple” can imply drastically different search intent. Here is a sample demonstrating context changes:

Main Keyword	Apple
Paired with:	“Recipes” or “Nutrition”	“MacBook” or “iPhone”
Looking for:	Fruit	Brand

Use semantic variations and related keywords to enrich content and reinforce relevance, as this will support your SEO objectives while catering to the needs and interests of your audience.

Best Practices for Incorporating SEO keywords into content

Incorporating SEO keywords effectively into your content is crucial for enhancing search engine visibility while captivating and retaining your target audience’s attention. Following best practices ensures your keywords appear natural to search engines and readers.

On-page Optimisation techniques

Using keywords effectively involves placing them in strategic locations across your content. The best practices involve a subtle blend of frequency and placement to appear natural to search engines and human readers. Several strategic placements are paramount:

1. Title Tags: Title tags are among the most important on-page SEO factors to include primary keywords. The title tag appears as the clickable headline in search engine results, and search engines use it as a primary ranking factor. Ensure your keyword is placed near the beginning of the title for maximum impact.

An engaging and keyword-optimised title can improve click-through rates (CTR), which indirectly helps with rankings. A balance between keyword usage and engaging language is essential for captivating the reader’s attention.

2. Meta Descriptions: While not a direct ranking factor, a compelling meta description featuring a target keyword can improve click-through rates from search engine results pages (SERPs). A good meta description can signal users that your content is relevant to their search query, encouraging them to click.
   
3. Headings and Subheadings (H1, H2, H3): Place your primary keyword in the H1 tag (main heading) and secondary or related keywords in the H2 and H3 tags (subheadings). This helps search engines understand the structure and hierarchy of your content while also making it easier for readers to skim and understand​.
   
4. Body Content: Incorporate your keywords naturally throughout the body content. However, avoid keyword stuffing as it can harm user experience and website rankings. Also, use synonyms and related terms to enhance content depth and improve your chances with search engines using latent semantic indexing (LSI).
   
5. Images and Alt Text: Alt text provides an image description on a web page, which is essential for accessibility and image SEO. Adding relevant keywords in the alt text helps search engines understand the content of your visuals, enhancing the page’s visibility in image search results. To optimise alt text:

• Keep it descriptive and concise.
• Ensure relevance to the image and topic.
• Use varied keywords to maintain freshness.
  

6. URLs: A short, keyword-rich URL that includes your primary keyword in the URL can help search engines and users quickly understand the page’s content. Keep URLs short, clean, and descriptive for better user experience and search engine performance. Long, complex URLs can be difficult for users and search engines to navigate.

Keep in mind that although these on-page elements are essential for optimisation, they should always be implemented with a focus on maintaining the quality and readability of the content.

Keyword mapping strategy

Keyword mapping is a crucial SEO practice that involves assigning specific keywords to individual pages on your website to match search queries and user intent effectively. It ensures that each page targets a unique set of keywords,  preventing keyword cannibalisation and aligning with search engine best practices. Here’s how to approach it:

1. Identify Relevant Keywords

Conduct comprehensive keyword research using Ahrefs, SEMrush, or Google Keyword Planner. Focus on gathering a mix of broad (short-tail) and specific (long-tail) keywords. These keywords should mirror your content strategy and reflect the terms your target audience uses in search queries.

2. Classify Keywords by Search Intent

Not all keywords serve the same purpose. Analyse the search intent behind each keyword—whether informational, transactional, or navigational. 

3. Assign Primary and Secondary Keywords

Once you have a broad set of keywords, assign primary keywords to the most relevant pages on your site. Then, identify secondary keywords that support the primary keyword and align with subtopics or user queries. Secondary keywords should not have enough volume or intent to warrant their pages but should complement the main keyword.

4. Map Keywords to Specific URLs

Each keyword cluster should be mapped to a specific URL. If a page doesn’t exist for a certain keyword cluster, it indicates an opportunity to create new content. This also ensures that your site’s structure is optimised for SEO and that no two pages compete for the same keyword. This prevents keyword cannibalisation, which can confuse search engines and weaken your ranking potential. Carefully mapping unique keywords to each page can prevent this issue and help search engines identify the most relevant page for a query. 

5. Align Content with Search Intent and User Needs

For each page, ensure the content aligns with the user’s intent behind the keyword. For instance, transactional pages should feature product details and CTAs, while informational pages should provide in-depth answers or guides. This boosts user satisfaction and improves rankings.​

This approach not only helps organise your SEO efforts but also aids in creating a user-friendly site architecture.

Semantic keywords and LSI

Semantic keywords and Latent Semantic Indexing (LSI) help search engines understand the primary keywords and the context and meaning behind your content. This enables a more comprehensive approach to SEO, moving beyond traditional keyword matching to a more nuanced understanding of content relevance and user intent.

• Semantic keywords are phrases that are related to the primary keyword. They help provide additional context to your content, ensuring that search engines like Google can understand the discussed topic accurately. Including these related terms enhances the depth and breadth of your content, which improves your chances of ranking for multiple contextually related searches. 

For example, if your primary keyword is “coffee,” semantic keywords might include “caffeine content,” “espresso machine,” or “coffee beans,” helping search engines categorise your content more accurately.

• Latent Semantic Indexing (LSI) is used by search engines to evaluate the relationship between various concepts and terms within content. Including LSI keywords is crucial for a well-rounded content strategy, ensuring the content is keyword-rich and contextually relevant. In practice, use semantic keywords to:
  • Enhance topic authority
  • Improved Context and Relevance
  • Optimising for User Intent
  • Avoiding Keyword Stuffing

This broader keyword net can capture additional search queries and provide users with more comprehensive information.

Linking practices

Using keywords in anchor text—the clickable text portion of a link—can help search engines and users understand the context and relevance of linked content. Here’s how to best utilise linking practices to support your SEO keyword strategy:

1. Anchor Text Diversity: Avoid overusing exact-match keywords in your anchor text. Vary anchor text with related phrases to your primary keyword to prevent penalties and create a natural link profile.
2. Context and Relevance: Ensure anchor text accurately represents the content it links to. Misleading anchor text disrupts user experience and SEO performance—for example, linking “SEO keyword research tools” to relevant content​.
3. Internal and External Linking: Use SEO keywords naturally in internal links to connect related content and distribute link equity across your site. This strengthens SEO efforts while enhancing site navigation. On the other hand, when linking to external sites, ensure SEO keyword anchor text flows naturally and adds value by pointing to authoritative sources.
4. Avoid over-optimisation: Mix keyword-rich anchor text with branded or generic terms to avoid over-optimisation. Diversify anchor text using synonyms and variations to keep content natural.

Monitoring and evaluating keyword performance

Monitoring and evaluating SEO keyword performance is essential for optimising your content strategy and ensuring long-term search engine visibility. It involves regularly assessing the effectiveness of your target keywords in driving traffic, engagement, and conversions. Tracking this performance enables you to refine your strategy and respond to search trends or user behaviour changes.

To evaluate keyword performance:

1. List SEO keywords for which you aim to rank.
2. Use tools to track how your keyword rankings change every month.
3. Analyse the monthly search volume and any seasonal fluctuations.
4. Assess the relevancy of keywords to user search intent.
5. Adjust the content strategy based on keyword results to improve overall SEO.

Key Performance Indicators (KPIs) for Keyword Monitoring

• Keyword Ranking: Your keyword’s position on search engine results pages (SERPs). 
• Search Volume: The number of searches a keyword receives within a specific timeframe. High search volume indicates demand for that keyword but may also come with high competition.
