Data from 2026-09-08 — 30 days old.

Assessment summary

A low posting frequency (about one post every two to three days) combined with the complete absence of third-party ads ensures an integration stays visible to the audience for a long time.

However, the dispersion of views is notable (CV 0.81), and the median reach over the last three months has dropped from 2,548 to 1,821, so the final attention to a post will strongly depend on the resonance of the topic.

What grade A+ means

The metrics agree with each other: views and reactions are distributed as usual, and almost no signals lower the index.

Compared with similar channels

Compared with 15 News and Media catalog channels whose metrics look normal. They are a similar size: 4,183 to 22,977 subscribers.

ERR (reach) higher than 9 of 15
@kostromama 18.2%
similar channels median 16.6%
Reactions per 100 views higher than 8 of 15
@kostromama 1.25
similar channels median 1.07

This is not a niche norm: only catalog channels are included. A high ERR is not always a plus: if the other metrics do not support it, the index goes down.

Questions about @kostromama

Are there any signs of subscriber or view manipulation detected on the channel?

No, the channel received a minimal risk score of 2 out of 100. Audience growth and view dynamics look natural for an independent regional media outlet.

What reach will an advertising post receive?

The median reach is around 1,800 views per post. Due to a noticeable dispersion of views (CV 0.81), high-interest topics gather significantly more views than routine updates.

Is buying ads on this channel justified?

Placement is justified: the feed is free of ads and reposts, and thanks to the rare posting schedule, the post won't get lost in a stream of messages.
