Keyword research for bloggers
Keyword research is the foundation of SEO. Before writing a single word, you need to know which terms people are searching for — and, critically, which ones your blog can realistically rank for.
The core concept: keyword difficulty vs. search volume New blogs cannot rank for high-competition keywords like "best credit card" or "how to lose weight." Big sites with years of authority dominate those. Instead, target low-competition, long-tail keywords — specific phrases with 3–5 words, lower search volume, and far less competition.
Tools for keyword research: - Google Keyword Planner (free): Requires a Google Ads account. Shows monthly search volumes and competition levels. The best free starting point. - Ubersuggest (free tier): Neil Patel's tool gives keyword ideas, difficulty scores, and competitor analysis. Free for limited daily searches. - Ahrefs (paid, from $99/month): The gold standard for serious bloggers. Keyword Explorer shows exact difficulty scores, click-through rates, and which pages currently rank. - Semrush (paid, from $130/month): Comparable to Ahrefs. Particularly strong for competitive analysis — see exactly which keywords your competitors rank for. - Google Search Console (free): Once you have traffic, this shows exactly which queries people use to find your site — gold for finding new content opportunities.
Understanding keyword intent: - Informational intent: "how to," "what is," "why does" — the person wants to learn. Blog posts with tutorials, guides, and explanations serve these searches. Most blog traffic comes from informational intent. - Commercial intent: "best," "review," "vs," "alternatives" — the person is researching before buying. These keywords often have strong affiliate monetisation potential. - Navigational intent: searching for a specific brand or site. Hard to intercept unless you're writing about that brand.
How to evaluate difficulty for new blogs: Target keywords where the current top 10 results include forum threads (Reddit, Quora), old articles (2019 or earlier), or sites that don't specifically address the exact query. These are weak incumbent signals. If the top 10 is dominated by Forbes, HubSpot, and Healthline, skip it for now.
Aim for keywords with: - Monthly search volume: 100–2,000 (lower volume = lower competition) - Keyword difficulty score below 30 (on Ahrefs/Semrush scale) - At least one result in the top 10 that isn't specifically optimised for the query
Topic clusters and pillar pages: Don't write isolated articles. Build clusters: one comprehensive "pillar" page covering a broad topic (e.g., "SEO for bloggers"), supported by several "cluster" articles covering subtopics in depth (e.g., "keyword research for beginners," "how to write a meta description," "what is a canonical URL"). Internally link cluster articles to and from the pillar page. This signals topical authority to Google.
