B2B keyword research is more about finding keywords with high business value rather than high search volume.
Keywords with high business value = Keywords where you can promote the business offerings.
Example:
For a corporate gift manufacturing company, the following keyword types have high business value:
-why corporate gifting is important
-how much to spend on gifts
-when to give gifts to employees
-corporate gift ideas for clients, etc.
A common mistake in B2B SEO: ignoring low search volume keywords (say 10, 20) despite having high business value.
This is a mistake that we should avoid. In the B2B segment, buying intent of a keyword is much more important than the actual search volume shown in SEO tools.
In general, B2B industries tend to have lower search volume comparatively.
This is why it is okay to target keywords with a search volume as low as 10 if it has high business value and less competition in the SERP.
Here’s the keyword categorizing chart for B2B SEO:

Action items:
Give top priority to keywords with high business value (Zone I and Zone II in the chart) even if the search volume is as low as 20.
Chasing keywords with high search volume and low business value (Zone III and Zone IV) as a standalone metric doesn't make sense unless the business model is to drive revenue via display ads.

Soooooooooo under rated. It's much easier to rank, and despite not seeing massive amounts of traffic, you're going to get actual sales, which is what matters
Completely agree! Plus software like Ahrefs definitely under estimates traffic for keywords or just gets it wrong a lot of the time for the 'smaller' search volume keywords.
