SEO TAM SAM SOM visibility: How to increase in 30 mins

Calculating SEO TAM SAM and SOM are easy to understand. Refinement done every 3 months is what makes the difference towards a great outcome.

SEO TAM visibility = How much traffic can you get in next 3-6 months

Broadly, there are 5 steps:

  1. Go to Ahrefs
  2. Open Keyword Explorer
  3. Input an important keyword
  4. Pick all sites ranking for that keyword
  5. Filter sites with DR < yours

These are sites you can beat with 3-6 months of effort.

And… done!

Their total traffic is your SEO TAM.

This is a good way to start especially if

  • Your SEO traffic has been stagnant OR
  • You want SEO results to be more reliable

High level, this is the road… But here’s what it is in detail:
