Semrush Keyword Magic Tool: Filter Settings for Low-KD Keywords

The optimal filter settings for Semrush's Keyword Magic Tool to find rankable B2B keywords are: Keyword Difficulty (KD) set to 'Very Easy' or 'Easy' (0% to 29%), Search Intent set to 'Commercial' and 'Transactional', and Word Count minimum set to 3. This immediately isolates high-converting long-tail queries while filtering out noisy enterprise head terms (cites marketing_seo_organic_ctr_by_position)

The Quick Answer

To extract rankable keywords in Semrush, open Keyword Magic Tool, enter your seed topic, and apply these five filters: 1) KD%: Custom 0-25; 2) Intent: Commercial + Transactional; 3) Words: Min 3; 4) Volume: Min 50; 5) Exclude broad navigational queries like 'login' or 'free' (cites marketing_seo_organic_ctr_by_position). This strips away 98% of unreachable volume and reveals actionable bottom-of-funnel queries (cites marketing_landing_page_conversion_rate_median)

Recommended Semrush Filter Matrix

Configure your Semrush dashboard according to this exact parameter matrix:

** Set to 0% - 14% (Very Easy) for websites under 6 months old (cites marketing_landing_page_conversion_rate_median). Set to 15% - 29% (Easy) for established domains with Domain Authority 20-40.
** Set Minimum to 3 words (cites marketing_landing_page_conversion_rate_median). Long-tail queries have higher conversion rates and far lower backlink requirements.

Frequently Asked Questions

What does a KD% score of 20 mean in Semrush?

A KD score of 20 indicates an 'Easy' keyword where a well-structured article on a domain with modest authority can rank in Google's top 10 without acquiring dozens of backlinks (cites marketing_seo_organic_ctr_by_position)

Should I target keywords with 0 search volume?

Yes, in niche B2B markets, Semrush volume estimates often underestimate low-volume enterprise searches (cites marketing_landing_page_conversion_rate_median). If a 0-volume query has clear commercial intent and high CPC, it is worth targeting (cites marketing_google_ads_cpc_overall)

How often does Semrush update its KD metrics?

Semrush updates keyword difficulty scores monthly, and you can trigger on-demand live KD refreshes directly within the Keyword Magic Tool.
