Bluesky Keyword Monitor

Tracks keywords on Bluesky and alerts you only to new posts you haven't seen before — built for ongoing brand and topic monitoring, not one-off scraping.

What it does

Give it a list of keywords (a brand name, product, competitor, or topic). Every time it runs, it:

1. Searches Bluesky for each keyword.
2. Filters out posts older than your chosen lookback window and, optionally, posts with too few likes.
3. Checks each matching post against a running memory of posts it has already shown you.
4. Returns only the posts you haven't seen yet.

Run it on a schedule (see below) and point it — or the dataset it produces — at your alerting/notification tool of choice, and you get a running feed of new mentions instead of a pile of duplicates to sift through by hand.

Why "only new posts" matters

A normal keyword scraper returns everything matching your search on every run — so if you run it every hour, you see the same popular posts over and over, and it gets harder to spot what's actually new. This Actor keeps a memory of what it has already shown you, so each run's output is a clean list of genuinely new mentions. That's what makes it usable as a monitoring/alerting tool rather than a one-time export.

Input options

Field	What it does	Default
Search terms	Keywords/phrases to watch, searched separately	["Apify"]
Max posts per term	How many recent matches to check, per term, per run	50
Lookback window (hours)	Ignore posts older than this	24
Minimum likes	Skip low-engagement posts	0

Example output

Each new post becomes one row in the Actor's dataset:

postUrl	authorHandle	text	createdAt	likeCount	matchedTerm
bsky.app/profile/jane.bsky.social/post/abc123	jane.bsky.social	"Just tried Apify for a scraping project, works great"	2026-09-13T14:02:00Z	12	Apify
bsky.app/profile/devtools.bsky.social/post/xyz789	devtools.bsky.social	"Anyone compared Apify vs writing your own scrapers?"	2026-09-13T15:41:00Z	4	Apify

(Full rows also include authorDisplayName, repostCount, and replyCount.)

Suggested schedule

• Brand/reputation monitoring (time-sensitive): every 30–60 minutes, with a lookback window of 1–2 hours.
• General topic tracking (less urgent): every 4–6 hours, with a lookback window of 24 hours.

Keep the lookback window comfortably longer than your run interval — that way, if a single run runs late or fails, you won't miss posts that fell in the gap.

Bluesky login (one-time setup)

Bluesky blocks anonymous searches from cloud servers, so this Actor needs to log in with a real account to read public posts. It only ever reads — it never posts, follows, or likes anything.

1. Sign in to bsky.app (create a free account if you don't have one).
2. Go to Settings → Privacy and Security → App Passwords.
3. Click Add App Password, name it something like "keyword-monitor", and copy the generated password (looks like xxxx-xxxx-xxxx-xxxx).
4. Paste your handle (e.g. yourname.bsky.social) into the Bluesky handle field, and the app password into Bluesky app password.

Never use your real account password — only an app password, which can be revoked at any time from the same settings page without affecting your normal login.

Notes

• The Actor remembers post IDs across runs so it never shows you the same post twice; that memory is capped at the 5,000 most recently seen posts.
