How do I do keyword research for affiliate content?
Find the right keywords
Start with seed terms in your niche, then expand using tools like Google autocomplete, 'People also ask,' and keyword planners (Google Keyword Planner, Ahrefs, Semrush, Ubersuggest). Look for modifiers like 'best,' 'review,' 'vs,' 'alternative,' 'for beginners,' and 'worth it.'
Prioritize commercial and transactional intent: product reviews, comparisons, and buying guides. Informational keywords can work too if they naturally lead to a tool or product recommendation.
Check search volume and keyword difficulty. New sites often do better with long-tail phrases (4+ words) and low-competition terms. Typical volume ranges: long-tail might be 100–1,000 searches per month; head terms can be 10,000+ but are much harder.
- Product name + review
- Product A vs Product B
- Best [category] for [use case]
- [Product] alternatives
- Is [product] worth it?
Validate before you write
Search your target keyword and study the top 10 results. If they are all major brands or thin affiliate sites, it may be hard to rank. If you see forums, Quora, or outdated posts, there may be an opportunity.
Look for content gaps: missing comparisons, no pricing details, or no real-world examples. Your post should be more useful than what already ranks.
Group related keywords into one comprehensive article rather than many thin posts. Track rankings and update as you go.
- Check top 10 results for competition
- Look for outdated or thin content
- Identify gaps you can fill
- Cluster related keywords into one post
Common mistakes
- Targeting only high-volume head terms that are too competitive for a new site.
- Ignoring search intent and writing a review for an informational query.
- Choosing keywords without checking whether the top results are actually affiliate-friendly.
