Published 10 October 2026 · by Dan · Guides. Your competitor's unhappy customers have already written your next landing page. They post what broke, what got more expensive and what support never answered. They do it in public, in their own words, and some of them ask for an alternative in the same post. Most teams never read those posts in any organised way. This guide shows where to look, how to sort what you find, and what to do with it. ## Where complaints are public - **Developer and founder forums.** Long threads with detail. Search for the product name plus "alternative", "switching from", "moved off" or "pricing". - **Review sites.** Read the three-star reviews. Five-star and one-star reviews are short. Three-star reviewers explain what they like and what they can't stand. - **The competitor's own community.** Public feature-request boards and community forums show what customers have wanted for two years. - **Public issue trackers.** For developer tools, the open issues with the most reactions are the complaint list. - **Replies under launch posts.** When a competitor announces a price change, the replies tell you who is leaving. Stay on public pages. Read each site's terms before you collect anything from it with a tool, and don't sign up to a competitor's customer community under a false name. ## Two kinds of post Sort every post into one of two kinds before you do anything else. A **complaint** says something is wrong: a price rise, an outage, a missing feature, slow support. Complaints tell you what to say in your marketing. A **switching post** says the person is leaving or looking: "what are people using instead of Acme CRM?" Switching posts tell you who to talk to this week. They are rarer and they go stale within days. _Product preview: an illustrative example. Companies and changes are fictional._ ## Log each one the same way One post proves nothing. A log lets you count. Use the same fields for every entry, and copy the quote word for word. Both companies below are made up. **Complaint log entry** _A fictional example._ - **Date:** 8 October 2026 - **Competitor:** Cedar Support - **Kind:** Switching post - **Theme:** Price - **Quote:** “Our bill went from €180 to €310 a month with no new features. What is everyone moving to?” - **Source:** A public forum thread, with the link saved. - **Who:** A support lead at a company of about 20 people. ## Count the themes After a month, tally the entries by theme. Keep the list of themes short: price, reliability, missing feature, support, hard to use. This example counts twenty made-up posts about one competitor. **20 public complaints about one competitor, by theme** | | Value | | --- | --- | | Price | 8 | | Support | 5 | | Reliability | 4 | | Missing feature | 2 | | Hard to use | 1 | Illustrative numbers. Count your own before you act on them. Check two things before you trust the tally. First, that the posts come from different people. One angry customer posting in five places is one complaint. Second, that the complaints are recent. A reliability problem from two years ago may be fixed. ## Turn the top theme into a reason to switch A theme is useful when you can answer it honestly. Take the top one and ask whether you are better at it. If you are, you have material for three places. **Your comparison page.** State the fact that answers the complaint. If their customers complain about surprise price rises, show your prices and say how long they are fixed. **Your sales notes.** Add the theme to your [battlecard](https://plainrival.com/blog/battlecard-template) with one real quote, so a salesperson can say "we hear that a lot" and mean it. **Your replies.** When someone asks in public for an alternative, answer the question they asked. Say what your product does about their problem, say what it doesn't do, and say that you work there. If you aren't better at it, the tally is still worth having. It tells you what not to claim. ## What not to do - **Don't quote people in your marketing without asking.** A public post isn't permission to put someone's name on your home page. - **Don't pile on.** Replying to every complaint thread with a link to your product gets you banned and remembered. - **Don't invent a pattern.** Three posts are three posts. Say "some customers" only when you have counted them. - **Don't attack the competitor.** Answer the problem. Buyers trust the calm reply. ## Let a tool do the searching Searching five places for five competitors every week is the part people give up on. A switching post from last month is worth little, so it is also the part where being late costs most. [Complaint signals](https://plainrival.com/features/complaint-signals) in Plainrival does the searching. It looks for new public posts on Hacker News about each competitor you track, every few hours. It keeps the complaints and the switching posts, drops the rest, and links each one to its source. The strongest ones appear in your [weekly brief](https://plainrival.com/features/weekly-brief), and an opportunity report sums up one competitor's pains and missing features with quotes. The sorting into themes and the honest answer are still your job. They take an hour a month once the posts arrive without you looking for them. ## Questions about competitor complaints ### Where can I find complaints about a competitor? Public forums, the three-star reviews on review sites, the competitor's own feature-request board, public issue trackers and the replies under its pricing announcements. ### How many complaints make a pattern? Look for the same theme from at least five different people within a few months. Fewer than that is a lead to watch, not a claim to make. ### Can I reply to people who complain about a competitor? Yes, when they ask for an alternative and the forum allows it. Say who you are, answer their question and mention what your product doesn't do.
