Technical SEO is a tailored Slack community exclusively focused on (you guessed it) technical SEO.
It started in 2016 with a conversation between Patrick Stox, Paul Shapiro, and Brian Ta and eventually led to the creation of /r/TechSEO on Reddit.

Conversations predominantly take place in channels like #general, #random, and #must-reads, reflecting the community’s focused nature on technical SEO without the need for many unnecessary channels.

Originating from a subreddit, BigSEO transitioned into a Slack group to offer a more interactive and advanced platform for SEO discussions, thanks to Steven Van Vessum’s initiative in 2016.
Although the subreddit now has over 106,000 members, the Slack community has remained relatively small and tight-knit over the years with around 8,500 members.
This Slack community has become a hub for experienced marketers to exchange insights, forge business connections, and even kickstart collaborations.
With channels covering a wide range of SEO and marketing topics, including #business, #must-reads, #sitereview, #technical-seo, #tools, #analytics, #localseo, and a #jobs channel for career opportunities, BigSEO stands out as a vibrant space for those looking to advance their SEO knowledge and network with peers.

Measure is one of the oldest SEO communities around going back almost a decade. It started as a small chat on a platform called Beluga but has now grown to a flourishing Slack community with over 23,000 active members.
Some of the current, active channels are listed below, including a dedicated channel for SEO and SEM.
My favorite thing, however, is this Looker Studio report with the community’s usage stats, very on-brand! Since SEO involves a lot of data and analytics, you’re sure to find a ton of value in the non-SEO channels in this community too.
