What Is a Keyword?
A keyword is a word or phrase that people type into search engines when looking for information that meets their needs.
In SEO (Search Engine Optimization), a keyword refers to the specific term you want your website to rank for in search results to attract your target audience.
This audience consists of users whose searches match the content and focus of your website.
For example, if you run an online shoe store, you might target keywords like "shoes," "men’s shoes," or "leather shoes." These terms are likely to draw the right visitors, whereas unrelated searches like "summer travel destinations" wouldn’t be relevant.
Some websites cover multiple related topics and can attract visitors searching for any keywords within those categories. For instance, a large fashion site might include shoes, outfits, accessories, and jewelry, appealing to a broad range of search terms.
Why is a keyword important?
If you own a website, keywords are at the top of the list of the most important things you must work on. Here is why they are so important:
From the User’s Perspective
Users enter keywords expecting to find websites that answer their questions. Choosing the right keywords ensures your site matches their intent, increasing the likelihood they’ll visit your page. For example, someone searching for “best travel destinations in Pakistan” wants information specifically about Pakistan, not other countries.
From the Search Engine’s Perspective
Search engines analyze keywords to judge how relevant your content is to users’ queries. If keywords are irrelevant or misused, your site’s ranking will suffer. For example, a packaging company using keywords like “COVID vaccine” will not rank well because those terms don’t relate to their content.
From an SEO Perspective
Keywords help optimize your pages to increase targeted traffic. Selecting the right keywords for your audience means users find exactly what they want when they visit. Misleading keywords that don’t reflect your content can harm your SEO.
From a PPC (Pay-Per-Click) Perspective
PPC ads rely on bidding for keywords. Choosing relevant keywords lets advertisers reach users interested in their offerings and avoid wasting budget on irrelevant clicks.
Types of Keywords
Head Terms vs. Long-Tail Keywords
Head terms are short, broad, and highly competitive (e.g., “digital marketing”).
Long-tail keywords are longer, more specific, and less competitive (e.g., “best digital marketing techniques for small businesses”).
Seed keywords
Short, high-volume keywords without modifiers that form the basis for creating longer, more specific keywords.
Branded & non-branded keywords
Branded keywords include brand names (e.g., “SEODebate Chrome Extension”).
Non-branded keywords focus on products or services without mentioning a brand (e.g., “website domain rating checker”).
Negative keywords
Used in PPC campaigns to prevent ads from showing on irrelevant searches that might waste budget.
Primary & secondary keywords
Primary keywords are the main focus of your content.
Secondary keywords support and refine the topic, helping search engines understand your niche better.
Geo-targeting keywords
Include location-specific terms to attract local audiences (e.g., “restaurants in Dubai”).
Topical & evergreen keywords
Topical keywords trend for a short time (e.g., “Christmas celebration ideas”).
Evergreen keywords maintain consistent search interest (e.g., “how to lose weight”).
LSI (latent semantic indexing) keywords
Terms related to the main keyword that help search engines better understand context (e.g., “SEO” related to “digital marketing”).
LSI keywords are neither long-tail keywords nor synonyms of the main keywords. They are related to the words of the main keywords that search engines can recognise and fetch the required results.
How to Evaluate Keywords?
Competition: How many people search for the keyword; more general keywords usually have higher competition.
Keyword Difficulty: Measures how hard it is to rank in the top search results for that keyword.
Competitive Density: Indicates how many advertisers are bidding on the keyword in paid campaigns.
Search Volume: Number of searches a keyword gets over time.
Length: Shorter keywords tend to be general, while longer keywords are more specific.
Cost: Highly competitive keywords often cost more in paid advertising.
