Question and answer platforms let you show expertise and reach people at the moment they are looking for help. Links are usually nofollow, so the payoff is visibility, trust and referral traffic, not direct ranking value.
Platforms worth using
| Platform | Best for | Notes |
|---|---|---|
| Quora | General, business and professional topics | Answers can keep ranking and getting views for a long time. |
| Niche communities on nearly any subject | Each community has its own rules on self-promotion. | |
| Stack Exchange network | Specialist topics, from SEO to cooking to law | Strict quality standards. Answers must be complete and accurate. |
| Stack Overflow | Programming questions | Disclose affiliation if you link to your own tool or project. |
| Indie Hackers | Startups and bootstrapped products | Community values transparency and shared lessons. |
| Brainly | Student homework help | Relevant for education and learning topics. |
Ignore this one: Yahoo Answers closed in 2021. If a list still includes it, the list is outdated, so be careful with everything else on it.
How to answer well
- Answer the question completely before mentioning yourself or your site.
- Be specific. Steps, examples and numbers are more useful than general advice.
- Disclose your connection if you link to something you own.
- Link only when it adds value, for example to a detailed guide or a tool.
- Follow up if people ask questions in the comments.
- Pick your battles. Five excellent answers a week beat fifty quick ones.
Use real questions as ideas for your next article too. If many people ask the same thing, a full guide on your own site can become a link-worthy resource. See our link building strategy.
