Stack Overflow is the leading Q&A community for developers and programmers worldwide, where users post questions, provide answers, and build reputation through contributions. It's ideal for tech startups and founders seeking to engage with a massive audience of over 100 million monthly visitors, primarily in Startup Communities.

For SEO value, it offers a rare opportunity for a dofollow link on high-authority profiles (Domain Rating: 27), but requires >2000 reputation earned via active participation like answering questions. This single link appears next to your Twitter logo on your profile page, driving targeted referral traffic from developers. Unlike typical directories, links here carry weight due to the site's immense domain authority and organic traffic, though they're profile-based rather than submission listings.

Tips for getting listed: Create a profile and actively contribute by answering questions in your niche to build reputation quickly—aim for 2000+ points. Once achieved, add your startup's URL in the website field for the dofollow link (example: search for "backl.io" profile). Avoid spamming; focus on genuine value to sustain engagement and prevent moderation issues. Monitor reputation via your profile dashboard for progress.
