Low‑frequency keywords (LF)
Narrow, specific queries with low search volume.
Low‑frequency keywords (LF) are search phrases with a monthly search volume of less than 100–200 (the exact threshold varies by niche). They are typically longer and more specific than medium‑ or high‑frequency keywords and show a high level of purchase intent.
What are low‑frequency keywords
Low‑frequency keywords (LF) are search phrases that are entered relatively rarely. Their main value is the precise match to user intent. A person searching for a specific part is almost ready to buy.
Example
'Buy laptop hinges for Asus ROG Strix G15' is a typical LF query. Traffic is low (maybe 5–10 searches per month), but conversion is maximal because the user is looking for a very specific part.
Strategy
- Thousands of pages — via tags, filters, categories (for e‑commerce)
- Long‑form articles — for informational sites, covering LF in FAQ sections or subheadings
- Semantic core should include as many LF queries as possible
Relation to the long tail
LF queries are almost always part of the long tail, but not every LF is long ('chair' — LF but not long). The long tail must consist of 4+ words. In practice, the terms are often used interchangeably.
