How to scrape Stack Exchange answers
Unlike most platforms, Stack Exchange gives you access on purpose. It runs a real, documented public API across Stack Overflow and its sister sites, and it publishes full data dumps of its questions and answers. So the wall here is not getting the data. A developer can query threads over the API or download a dump and work from it locally.
The catch is what to do with it. The API is quota'd and paginated, the dumps are large and only current as of each release, and either way you end up with a mountain of question-and-answer text that still has to be read and clustered before it means anything for an ad. Here is each route and its real limit.

Reading threads by hand
You can open a question, read the accepted answer and the highest-voted alternatives, and copy the lines that name a real problem. For one or two threads this is the fastest thing there is. It stops working when the angle you want is spread across dozens of questions, each with its own workarounds, and the pattern only appears once you have read all of them.
The official API and data dumps: real access, still raw
The Stack Exchange API returns questions, answers, comments, and vote counts as clean JSON, which makes it the honest developer route. It is throttled, though: requests are metered against a quota, responses are paginated, and heavier use expects a registered key. Plan for backoff and paging rather than one big pull. The published data dumps are the other option, a periodic export of the whole corpus, useful for bulk analysis but large to handle and stale between releases.
Either way, access is the solved part. You are left with structured Q&A that still needs to be read, deduped, and grouped into themes before it tells you anything about how to sell. The API and the dump hand you the corpus, not the angle.
The paste-a-URL route
Adlicio reads the public question and its answers on a thread through your own browser session, the same content any visitor sees, with no key and no quota to manage. Paste a thread URL and it collects the question and answers in about 60 seconds.
Then the thread comes back clustered into ranked angles: the precise problem people are stuck on, the workarounds they settle for, and the alternatives they reach for instead, each backed by verbatim quotes. Because it reads across the threads that match your topic, the recurring friction rises to the top on its own.
The 60-second version
- 01Pick the questions that name your buyer's problem
The most-viewed and most-upvoted questions in your niche, plus the ones whose accepted answer is a clunky workaround. That gap between the problem and the fix is where your angle lives.
- 02Paste the thread URL into Adlicio
Any public Stack Exchange thread, on Stack Overflow or a sister site. The scrape reads the question and its answers and finishes in about 60 seconds.
- 03Mine the friction, keep the quotes
Work from the ranked angles: the problem people burn days on becomes your hook, and the verbatim line proves you understand the pain better than a spec sheet does.
Questions people also ask
Does Stack Exchange have a public API?+
Yes, a real and documented one that returns questions, answers, and comments as JSON across Stack Overflow and its sister sites. It is metered by a request quota and paginated, so heavier use needs a registered key and some backoff handling.
What are the Stack Exchange data dumps?+
Stack Exchange periodically publishes a full export of its public questions and answers. It is comprehensive and good for bulk analysis, but the files are large and only reflect the corpus as of each release, so they go stale between dumps.
What is the Stack Exchange API rate limit?+
The API meters requests against a daily quota per key and applies short-term throttling if you burst too fast. The exact figures change over time, so check the current API docs rather than hard-coding a number.
Can I scrape Stack Overflow specifically for ad research?+
Yes. Stack Overflow is the largest site on the Stack Exchange network, and its questions spell out the exact problems people are trying to solve. Paste a thread URL into Adlicio and it returns those problems as ranked angles with verbatim quotes.
