100 Q&A Submission Sites Across multiple Niches
Q&A Submission Sites List: 100 Platforms Across Different Niches
Ask a question on the internet and someone, somewhere, will answer it. That simple idea runs some of the biggest sites on the web. Quora, Reddit, and Stack Exchange all live on people asking things and other people answering, usually from real experience.
For anyone trying to get noticed, that’s a real opportunity. A single good answer can sit in front of exactly the people looking for what you offer, sometimes for years.
There are hundreds of these platforms out there, covering almost every topic you can think of. This guide brings together 100 question and answer (Q&A) sites, grouped by category, so you can go straight to the ones that fit what you do.
How Q&A Sites Can Help With SEO
Q&A content lines up naturally with how people search. These answers are written as real questions, the same way users type things into Google, so they often match actual search queries closely.
Think about your own searches. Most of us type full questions into Google, and Q&A pages are written in that exact same question-and-answer format. That overlap is one reason these pages sometimes rank well, and occasionally sit above regular blog posts.
You can see this in the screenshot below. For the search “b2b seo,” Google shows a “Discussions and forums” section on the first page. The results include Reddit threads and a Quora question, along with details such as comments and vote counts.
Google pulls this kind of forum content into results, though not for every search. When it does, it’s one more way your answer reaches people, even without ranking as a normal link.
Here’s what a steady presence can realistically get you:
- Your answer showing up right when someone needs a solution
- Extra clicks from readers who want to know more
- Steady credibility as you keep showing up in your space
- A backlink now and then, when the platform allows it

What Usually Goes Wrong When You Post on These Sites?
Most problems here trace back to a handful of habits, and once you know them, they’re easy to avoid.
Most of these issues also tend to show up early, in your first few weeks on a platform. Once you’ve built a bit of history and a few upvoted answers, you get far more room to operate.
Accounts Get Flagged or Banned
New accounts get watched closely, and dropping a link in your very first answer is the fastest way to trip that wire. Answer four or five questions with no link at all before adding one, so the account looks like a real contributor and not a drive-by promoter.
Answers Get Deleted or Marked as Spam
An answer usually gets pulled when the link doesn’t fit the question, or the whole thing reads like an ad. Answer the question properly first, and only add a link at the end if it genuinely helps. A good test: if the answer still stands on its own with the link removed, you’re fine.
Good Answers Get Buried
On Reddit and Quora, a strong answer can vanish when it lands in a thread that already has hundreds of replies. Look for newer questions with only a couple of answers instead, where a good response has room to rise to the top.
Duplicate Answers Get Filtered
Posting the same answer word-for-word across several sites is easy to detect and often gets caught as spam. Rewrite each one to fit the specific question and community it’s going into.
Writing Answers That Actually Get Noticed
A good answer on these platforms reads like it came from someone who’s actually dealt with the problem, not from a brand trying to sneak in a link.
Start with the direct answer, not a warm-up paragraph. People scanning Q&A threads skip intros and look for the actual solution first.
Add something specific: a number, a tool name, a step you took, an outcome you saw. Vague, generic answers get scrolled past even if they’re technically correct.
Keep your answer short enough to read in one go. Long answers lose people halfway through, and readers stop noticing your link right there.
Building This Into a Regular Habit
Doing this regularly is what makes it work. A few good answers posted often will build your presence and search visibility far more than one big push ever will. The platforms reward it, search engines pick up on it, and real readers start to recognize you, all at once, with results that keep adding up over time.
Here’s a simple way to keep it going without burning out:
- Pick 2 or 3 platforms to focus on at a time, not all of them at once.
- Answer questions consistently on each, and keep that steady pace as you settle in.
- Set up alerts or follow relevant tags so new questions in your space come to you instead of you hunting for them.
- Fill out your profile properly on each site, with a real bio and photo, before you start answering.
- Move to new platforms once the current ones feel like a natural part of your routine.
- Reuse the knowledge you already have. If you’ve written about something for your blog or for a client, there’s usually a related question sitting on one of these platforms waiting for that same answer, just phrased differently.
- Save your best answers somewhere. When a similar question shows up later, you can adapt an existing answer instead of starting over.
- Review your list every few months. If a platform feels dead or isn’t getting engagement, swap it for another one from the list instead of forcing it.
