Assessment summary

English-language channel about web development: course cards on HTML, CSS, JavaScript, MongoDB and WordPress mixed with short breakdowns of layout techniques — from the gap property to the if() function in CSS. Across five years and ten months the base has barely moved: 133.9K subscribers two months ago against 133.7K now, and median views over that time grew from 11.2K to 12.9K.

A post is seen by 9.6% of subscribers — above the median of similar channels in the catalog (6.1%), though roughly a third of them have a higher share. Reactions are lower than in every similar channel in the catalog: 0.13% of views against 0.28%, so engagement is near zero. The last post went out 11 days ago at a usual pace of 0.7 posts per day — the feed updates rarely.

About the channel

English-language channel about web development for people learning frontend or already working with it: course cards on HTML, CSS, JavaScript, MongoDB and WordPress, short breakdowns of layout techniques and tool news. It has been running for almost six years, posts come with images, videos and code examples.

In the catalog it sits next to @udemy_learning with 42.9K subscribers and ERR 5.9% and @lexygpt with 199.4K and ERR 5.6%: this channel is larger than the first and smaller than the second, and a post is seen by a bigger share of subscribers than at @udemy_learning and bigger than at @lexygpt.

What it publishes:

  • Course cards: announcements with author, level and duration — from "Developing for Web Performance" to "Technical SEO".
  • CSS and HTML techniques: short posts with code — the gap property, clamp() for font size, custom list markers, responsive images.
  • Breakdowns and news: for example, "6 things you no longer need JavaScript for" and the arrival of the if() function in CSS.

Almost all posts go out in the morning on weekdays, there are no forwards from other channels. By subscriber count the channel is in the top third of the niche. Short notes with code examples and course cards; occasionally promo inserts off the topic turn up.

By subscribers, it ranks #4 of 26 channels in the Education niche of the catalog.

What grade A+ means

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

Channel content

⚠️ Mixed content signals

The feed has some standalone promo posts: an announcement of the GigaChat model and a post with a film that leads to a closed VIP subscription.

Compared with similar channels

Compared with 6 Education catalog channels whose metrics look normal. They are a similar size: 80,242 to 349,381 subscribers.

ERR (reach) lower than 5 of 6
@webdev_trainings 9.6%
similar channels median 13%
Reactions per 100 views lower than 6 of 6
@webdev_trainings 0.13
similar channels median 0.26

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.
