How Facebook group monitoring works in BuyerSpotter
BuyerSpotter is a Chrome extension that monitors Facebook groups, Reddit, LinkedIn, X (Twitter) and Nextdoor for posts where someone asks to buy, hire or get a recommendation, and alerts you so you can reply yourself. For Facebook, it reads the groups you select through the Facebook account already signed in to Chrome.
- Add up to 10 phrases a customer would write, such as "recommend a bookkeeper" or "need a plumber". Add exclusions for words you never want, such as "hiring".
- Pick up to 25 groups from the list of groups your account belongs to, or paste a group link.
- Let it check on a schedule. The first scan looks back 72 hours, so you can see results on day one.
- Review the inbox, open the original post and decide whether to reply.
Which groups can it monitor?
Any group your own Facebook account can open: public groups and private groups where you are a member. It cannot read a private group you have not joined, and it does not reveal posts that are hidden from your account. If a group is missing from the list, the troubleshooting steps in the user guide explain how to add it by link and check access.
Local trades often find the most requests in town and neighborhood groups; see the guides for handyman, painting and tree service leads. Bookkeepers can read how to get bookkeeping clients.
How often it checks and what that depends on
The minimum interval is set by the size of your setup:
- Up to 7 groups and 5 phrases: every 15 minutes.
- Up to 15 groups and 10 phrases: every 30 minutes.
- More than 15 groups: every 45 minutes.
Checks need Chrome open (minimised is fine) and a working Facebook sign-in. BuyerSpotter reads at a measured pace and slows down when a network asks it to. No tool can promise that Facebook will never limit an account, so the load is kept deliberately low.
From alert to reply
Each match shows the group, the post, the phrase that matched and a buyer-intent grade, so requests such as "Can anyone recommend a bookkeeper?" rank above promotions and job ads. Open the post in Facebook, read the thread and the group rules, and answer in your own words. The guide on replying to local buyer posts has examples, and the step-by-step article on how to monitor Facebook groups for keywords covers choosing groups and phrases.

Frequently asked questions
Can I get notifications for keywords in Facebook groups?
Facebook's own keyword alerts are an admin tool, so members cannot set them. BuyerSpotter works for members: it checks the groups you choose for your phrases and sends a desktop, Telegram or webhook alert when a post matches.
Do I need to be a group admin?
No. Membership is enough. BuyerSpotter reads what your own account can already see.
Does it work with private Facebook groups?
Yes, if your account is a member of the group. It cannot open private groups you have not joined.
Is it a Facebook group scraper?
No. It does not export member lists or contact details. It shows you posts that match your phrases, with a link to the original post.
How many groups can I monitor?
Up to 25 groups on Premium, with up to 10 search phrases shared across your networks.
Will BuyerSpotter post or comment for me?
No. It is read-only. You open the post and reply yourself.
