Case of promoting online courses

How SEO Became a Stable Sales Channel for an Online Course Website. A Real Case for an Online School.
Key Metrics (comparison of periods over 1 year of promotion):
Clicks: 6.6k → 15.6k (+136% growth)
Impressions: 113k → 664k (~6x growth in reach)
CTR: 5.9% → 2.3% (decrease)
Average Position: 17.6 → 6.7 (entry into TOP-10)

The sharp increase in impressions (113k → 664k) means:
the site began to rank for a significantly broader semantic range
new pages/categories/content were added

The qualitative growth in positions from 17 → 6.7 means:
– moving from the "second page" to TOP10
– into the zone of stable traffic

CTR decreased from 5.9% → 2.3% but this is not a problem:
the site began to appear for a broader semantic range
informational queries increased
This is a classic scaling effect.

Important: this is not just a growth case – it is a case of transitioning to SEO as a stable sales channel for online courses.
