Watchlists

A Marketplace watchlist is five fields and one habit

The fields are keywords, exclusion words, a price band, a radius, and how often it runs. The habit is going back and fixing them when the feed gets noisy — which it will, because the junk changes.

Get those right and alerts become something you clear in ninety seconds. Get them wrong and you will turn notifications off within a fortnight, which is what happens to most people who try this.

The builder needs no account. It gives you keywords and exclusions you can paste into any tool.

The five fields

Every alert product exposes some version of these. What differs is how much each one is allowed to do.

Keywords — be specific, then be plural

Model names beat category names every time. 'Bike' returns a city's worth of department-store bikes; 'trek', 'specialized', 'cannondale' returns the ones you can resell. Then add the variants: the spaced version, the unspaced version, the abbreviation, and the misspelling. Underpriced listings are frequently underpriced because the seller spelled it wrong and nobody else found it.

Exclusion words — where the quality comes from

This is the field that decides whether you keep using the watchlist. Accessory sellers, parts sellers and other buyers all legitimately use your keywords. Naming what disqualifies a listing is the only way to remove them, and it is why every category page here ships a starting exclusion list.

Price band — a floor is a junk filter

The ceiling is your walk-away price, worked out from resale value rather than habit. The floor does quieter work: nobody lists a working console at $5, so a sensible floor removes both the accessory listings that slipped past your exclusions and a share of outright scams. The exception is furniture, where free listings are often the best margin available.

Radius — what you will drive on a Tuesday

Set it to your realistic weekday willingness, not your best-case Saturday. A radius you never act on only makes the feed longer. Scale it to the margin: a graphics card justifies 40 miles, a $40 dresser does not.

Cadence — matched to the category, not the budget

Consoles and GPUs need speed. Furniture and appliances do not, because most buyers cannot transport them. Buying the fastest tier for a slow category is money that buys you nothing.

Exclusion words that pay off in any category

These twelve are worth adding to essentially every watchlist you build. They remove parts units, wanted ads, and rental posts — the three patterns that appear regardless of what you are hunting.

Category-specific exclusions do the rest of the work, and they differ a lot: consoles need accessory words, GPUs need mining words, apparel needs replica words. Each category page carries its own list, or the negative keyword generator will build one from what you type.

Fixing a watchlist that is not working

Six symptoms, six causes. Almost every complaint about Marketplace alert tools is one of these, and all of them are configuration rather than product failure.

Too many alerts, mostly junk

Almost always missing exclusion words. Look at the last ten alerts you ignored, find the word they have in common, and add it. Two or three rounds of this turns a feed you avoid into one you clear in a minute.

Alerts for accessories, not the item

Add 'only' phrases — 'controller only', 'battery only', 'case only'. Accessory listings almost always announce themselves this way, because the seller is trying to be clear.

No alerts at all

Usually the price band or radius is too tight, or the keywords are too obscure. Widen one at a time so you learn which was the constraint. FlipDar tells you when a scan ran and found nothing, which distinguishes 'no matches' from 'nothing ran'.

Alerts for things already sold

The cadence is too slow for the category. If listings are consistently gone by the time you message, that is the signal to move up a tier — it is the one situation where paying for speed is clearly worth it.

The same listing keeps appearing

Reposts are normal, and duplicate suppression handles the identical ones. A genuinely relisted item with a new price is worth seeing again: it means the seller did not sell at the old price, which is negotiating information.

Good deals you found manually never alerted

Your keywords are too narrow. Search the way the seller would write it, not the way the manufacturer would — including the wrong spelling.

Start from a category preset

If you would rather not start from a blank form, these are the seven configurations the free builder ships with — keywords, exclusions, price band and radius, with the reasoning for each.

Questions people ask

What is a Marketplace watchlist?

A saved definition of what you are looking for — keywords, exclusion words, a price range, and a radius around a location — that gets re-run on a schedule instead of you typing the search again. Facebook has its own saved-search feature; a watchlist in an alert tool adds exclusions, a cadence you control, and filtering before delivery.

How many watchlists do I need?

Fewer than you think at first. One well-tuned watchlist in a category you understand outperforms five vague ones, because the tuning is where the quality comes from. Most people are best served starting with one, getting the exclusion list right, and only then adding a second.

Can I use one watchlist for several categories?

You can, but it gets worse the more you mix. Price bands and exclusion words are category-specific — a floor that makes sense for consoles is wrong for furniture, and 'battery only' is meaningless outside tools. Separate watchlists keep both fields meaningful.

How do I write good exclusion words?

Read your own ignored alerts. The words you keep seeing on listings you never open are your exclusion list, and they are more accurate than any generic list because they reflect your market. The generator tool will give you a starting set to build on.

Do my existing watchlists change if I upgrade?

Your watchlists stay exactly as configured. Upgrading changes how many you can run and how often they scan — the search definitions themselves are untouched, and downgrading does not delete them.

Build it, then let it run

The builder is free and needs no account. When you want the search to run without you, the free FlipDar plan covers one watchlist on a 24-hour cadence with no card.
