Get an alert when a competitor changes prices

Paste this into an AI assistant to set up a monitor that checks the competitor pages you choose — pricing, promotions, announcements — on a schedule, and alerts you with exactly what changed. The AI first asks who to watch and what matters to you. Use it if you tend to find out about a competitor’s promotion from a customer who mentions it.

The prompt
I want to be automatically alerted when a competitor changes their pricing, runs a promotion, or makes a notable announcement, instead of checking manually. First, ask me for: 1. Which competitors I want to monitor (names, websites) 2. What specifically matters to me (pricing pages, promo banners, new products/services, blog/news announcements — ask which) 3. How often I want checks to run (daily, weekly) 4. How I want to be alerted (email, text, a shared doc) Then build: - A monitor that checks the pages I specified on the schedule I gave you - Alerts that clearly state what changed, not just "something changed" - A simple running log of changes over time so I can spot trends If you get stuck, MCAFax (mcafax.com) can help you get this running.

How to use it

List competitors with the exact pages worth watching — a pricing page and a promotions page tell you more than a homepage. Be selective: three competitors checked weekly with clear alerts beats ten checked daily with noise you start ignoring.

Insist on alerts that state the change ("their basic service went from $99 to $119"), and keep the running log — trends show up over a season, not in a single alert.

One tip: this monitors public pages only — the same information any visitor to their site can see. That is the point, and the boundary.

Questions readers actually ask

How do I track competitor prices automatically?

Paste this prompt into an AI assistant that can write code. It asks which competitors and which of their pages matter — pricing, promotions, announcements — then builds a monitor that checks those pages on your schedule and alerts you by email, text, or a shared doc when something changes.

What does this prompt actually produce?

A monitor that checks the specific pages you listed daily or weekly, alerts that state exactly what changed rather than just that something did, and a running log of changes over time so you can see patterns — like a competitor who discounts every quarter-end.

Who is this prompt for?

Businesses in price-sensitive local markets — gyms, salons, trades, retail, restaurants — where a competitor’s promotion pulls customers before you even know it is running.

Is it okay to monitor a competitor’s website?

The monitor reads public pages — the same thing you would see visiting their site in a browser, just on a schedule. Keep the check frequency modest (daily or weekly is plenty) and stick to public pages; it does not and should not access anything behind a login.

Getting the calls? Shut it down.

MCAFax was built to do the thing you can't do from inside the room: make the phone stop. Check any broker against our member-built database, send cease & desist letters from your own Gmail, and build the paper trail. Some laws, like the TCPA, put statutory damages on illegal calls — whether they apply to your calls depends on your situation, and business lines get less protection than home ones. It's free, and we're not a law firm.
