Quick guide
How to do keyword research
Keyword research turns one topic into a list of terms people actually search for on Google. The numbers are not AI guesses: they are real search data (monthly volume, competition and CPC) pulled from Google's database, so you can pick topics with proven demand.
What keyword research is
Keyword research is the process of finding which terms your audience types into search and how many people search for them. It is the foundation of SEO: it defines your blog topics, page structure and the priority of each piece of content.
What each metric means
| Metric | What it shows |
|---|---|
| Search volume | How many times per month, on average, the term is searched |
| Competition | How contested the term is (low, medium or high) among advertisers |
| CPC | Average cost per click in ads, signals the commercial value of the term |
How to pick good keywords
- Start with long tail: terms with 3+ words usually have less competition and clearer intent.
- Balance volume and difficulty: one huge contested term can return less than several medium ones.
- Read the intent: 'how to X' (informational) and 'best X' (commercial) need different content.
- Group by theme: several similar keywords become one strong article (a cluster).
Volume is not everything
A low-volume term with clear intent and little competition can convert better than a generic high-volume one. Think qualified traffic, not just big numbers.

Glossary terms
KeywordA keyword is the term or phrase a person types into a search engine and that a website chooses to target in order to appear in the results. In SEO, it is the bridge between what the audience is looking for and the content you publish: understanding which keywords your audience uses, with what intent and at what search volume is the starting point of any content strategy.LSILSI, short for Latent Semantic Indexing, is an information retrieval technique from the 1980s that identifies relationships between terms based on the patterns in which they appear together across many documents. In SEO jargon, the name ended up becoming a synonym for so called LSI keywords, the terms semantically related to a topic, even though Google states that it does not use LSI in its algorithm.Long tailIn SEO, long tail is the set of longer and more specific keywords, made up of three or more words, that have lower search volume but much clearer intent. Instead of fighting for generic, competitive terms, the long-tail strategy targets detailed queries like buy running shoes for overpronation, which attract fewer people but people who are much closer to deciding and converting.TF-IDFTF-IDF (Term Frequency, Inverse Document Frequency) is a statistical measure that weighs the importance of a word within a document relative to how often it appears across a whole collection of texts, known as the corpus. The logic is straightforward: a term that shows up a lot on a page but is rare in the rest of the documents tends to describe that content better. In SEO, TF-IDF helps you understand which words give context to a topic, even though it is not a direct Google ranking factor.Keyword researchKeyword research is the process of finding, evaluating and prioritizing the terms your audience types into search engines. It combines data on search volume, difficulty and intent to decide which words are worth investing content in. It is the foundation of any SEO strategy, because it defines what to write about and in what order, aligning production with people's real questions.Keyword stuffingKeyword stuffing is the practice of repeating a keyword in an excessive, artificial way inside a page, trying to manipulate Google rankings. Instead of helping, that forced repetition hurts readability, signals spam to the search engine and can trigger a penalty. Today it is seen as an outdated black hat technique, since the algorithms understand the context of the text and reward content written for people.Search volumeSearch volume is the estimated number of times a keyword is searched in a search engine, usually calculated as a monthly average. It shows the size of the demand for a term and is one of the first data points analyzed in keyword research, since it helps decide which topics are worth producing content for. Because it is an estimate, it should be read alongside difficulty and search intent, not in isolation.Keyword difficultyKeyword difficulty (KD) is the estimate of how much effort it takes to rank among the top results for a term, given the competition already holding those positions. SEO tools sum up that contest in a score from 0 to 100: the higher the number, the stronger the sites you would have to beat. It is a compass for choosing battles worth fighting, not a final verdict.Keyword cannibalizationKeyword cannibalization happens when two or more pages on the same site compete against each other for the same query on Google. Instead of joining forces, they split the relevance signals and the clicks, and the search engine gets unsure which one to show. The result is usually worse positions and less traffic than a single strong page would have on its own. Fixing cannibalization means reorganizing content so every search has a clear owner.Long-tail keywordA long-tail keyword is a long, specific query, usually with three or more words, that has low search volume but very clear intent and a high conversion rate. Instead of fighting over generic, crowded terms, you target detailed searches like best running shoes for overpronation, which attract fewer people but people much closer to deciding. Added together, these specific searches make up most of everything searched on the internet.Short-tail keywordA short-tail keyword, or head term, is a generic, short term, with one or two words, that gathers high search volume and, for that very reason, extremely high competition. Examples are shoes, marketing or insurance. Because the intent behind these terms is vague, they convert less and are very hard to rank, but they work as an anchor for a topic and signal authority when a site manages to rank them.Mid-tail keywordA mid-tail keyword is the intermediate term between the short tail and the long tail. It usually has two to three words, moderate search volume and competition, and a more defined intent than a generic term. Examples are running shoes or content marketing. It is considered the balance point of keyword research: it brings relevant traffic without the brutal fight over head terms.Seed keywordA seed keyword is the initial, broad term used as the starting point for keyword research. From a single seed, like coffee or marketing, SEO tools generate hundreds of variations, questions and related terms that you can turn into content. The seed is not the final target, but the trigger that opens up a topic's map of opportunities. It should not be confused with the seed phrase of cryptocurrency wallets, a completely different concept.Keyword densityKeyword density is the proportion of times a keyword appears relative to the total number of words in a text, expressed as a percentage. It is calculated by dividing the number of appearances of the term by the total word count. For a long time people believed in an ideal density, but today Google understands context and synonyms, so there is no magic number: what matters is using the keyword naturally, without forced repetition.
