SEO forums
SEO forums are the oldest SEO communities, and a few are still busy. Old forums count every account ever created, so their member totals run far ahead of how many people actually post.
Google Search Central Help Community
The Google Search Central Help Community is Google’s own forum for Search Console, indexing and ranking problems, answered by volunteer Product Experts and other users. Several threads were updated on the day we checked, including one about non-brand impressions collapsing on October 16.

SEO Slack communities
SEO Slack communities are smaller than the subreddits and slower, and the talk tends to stay professional because people post under their real names.
The SEO Community
The SEO Community is a free Slack group and events organization for people in search and AI optimization. It started in January 2021 as a weekly group chat, its stated values rule out selling links and guest posts, and it runs Tech SEO Connect on November 5 and 6, 2026, in Durham, North Carolina.

SEO Discord servers
SEO Discord servers are the newest kind of SEO community, and good ones are scarce: most servers listed under SEO in Discord directories sell links or guest posts.
We checked which SEO Discord servers have working invites and what each one is for. The AI SEO Discord is ours, built for questions about Google AI Overviews, AI Mode, ChatGPT and Perplexity.

SEO communities FAQ
These SEO communities FAQ answers cover the questions people ask most when looking for a place to talk SEO.
What is the best SEO forum in 2026?
The best SEO forum in 2026 depends on the problem: for Google indexing issues it’s Google’s own Search Central Help Community, and for everything else most of the activity has moved to subreddits like r/SEO and r/bigseo and to private Slack and Facebook groups. Moz said much the same when it closed Moz Q&A in December 2024.
Is Moz Q&A still open?
No, Moz Q&A is not open: Moz locked new posts and replies on December 12, 2024, and old threads are still readable.
Where can I ask SEO questions for free?
You can ask SEO questions for free on r/SEO, r/bigseo and r/TechSEO, in Google’s Search Central Help Community, and in the AI SEO Discord’s question forum. Here’s how to ask a question that gets answered.
What is the biggest SEO community?
The biggest SEO community by registered accounts is Warrior Forum, with 2,051,796, ahead of Black Hat World and Digital Point, but those totals count every account ever made. The biggest by members is r/SEO, at about 519,000 on GummySearch in October 2026.
