Competitor Monitoring for Small Businesses: A Free, Legal 30-Minute Routine

By Leon Harris, Founder & AI Creative Director · Updated July 2026

A competitor cut their price or launched a promo three weeks ago, and you only found out when a customer asked why you cost more. The information was never hidden — you just were not looking in the right place at the right time. What you want is to see the next price move, the next promo, and the next reputation slip early enough to answer it. This guide gives you a free, legal routine that takes about 30 minutes a week, with no logins to break and no software to buy.

Where the legal line sits

Everything in this routine reads content that is already public: a Facebook Page anyone can visit, Meta's own public ad database, and Google reviews anyone can see on Maps. That is fine. What is not fine is making a fake account to get inside a private group, or running a scraper — software that copies pages automatically — against a platform. Meta's Automated Data Collection Terms require express written permission before any automated collection from its products, and most platforms have a similar rule. You do not need any of that. What a competitor charges, what they are promoting, and what customers say about them is already sitting in plain view.

There is a Philippine rule worth knowing as well. The Data Privacy Act (RA 10173) governs how you collect, store and use personal data — names, contact numbers, photos of identifiable people — regardless of where you found it. Reading a review is fine. Building a file of reviewers' names and phone numbers is a different activity, one the National Privacy Commission takes seriously, and nothing in this routine needs it. Keep your notes about businesses and their public content, never about individual people.

Three free tools that do the actual watching

Google Alerts (google.com/alerts) is free and takes one afternoon to set up. Create alerts for your own business name, for each main competitor, and for a phrase like "[competitor] promo." Google emails you when something new is published. Know its blind spot: Google Alerts only covers pages Google indexes, so it largely misses social media and will not catch a quiet price change on a menu. Treat it as one input, not the system.

Meta Ad Library (facebook.com/ads/library) is Meta's own public tool for seeing every ad a Facebook or Instagram Page is currently running. No login is required. Set the country to Philippines and search the competitor's Page name, or open their Page and go to Page Transparency, then Ads from this Page. You see the actual ad image, the actual offer, and how long the ad has been running. An ad that has stayed live for weeks is usually one they are happy with — a useful hint, not proof. One hard limit: for ordinary business ads, Meta does not publish spend or reach. Those figures appear only for political and social-issue ads. You are reading what competitors say, not what they pay.

Google Business Profile, which you view through Google Maps or ordinary Google Search with no login, is where you check a competitor's new reviews, their rating trend and any new photos. This is often the most revealing of the three. A run of fresh 1-to-3-star reviews tells you something is breaking on their side. A burst of new photos often means a new menu, a renovation or a new room. A jump in good reviews may mean they just fixed something you have not.

The weekly 30 minutes

Block one slot a week — Friday afternoon works for most owners — and go in order:

5 minutes, alerts: skim the week's Google Alerts email and note anything relevant.
10 minutes, ads: check Meta Ad Library for each main competitor. Note new creative, new offers, and long-running ads.
10 minutes, reviews: check each competitor's Google listing — new reviews (read the 1-to-3-star ones closely), rating trend, new photos.
5 minutes, summary: paste your raw notes into a free AI chat tool such as ChatGPT, Gemini or Claude and ask for three to five bullets on what changed and what needs a response. Paste only public business content, never personal details about identifiable people.

A free Google Sheet with three columns — date, competitor, what changed — is enough. The point is to see a trend build over a month rather than react to one screenshot.

Turn it into a decision

The routine only pays for itself if it changes something you do. Three decisions are worth making every week. First, price: if a competitor drops theirs or bundles in an extra, decide within the week whether you match, undercut, or hold and explain your value — matching by reflex is how a whole market talks itself into a race to the bottom. Second, offers: if their promo ad has been running a while, decide whether you need a counter-offer or whether what makes you different already covers it. Third, review gaps: if their reviews keep mentioning something you do not offer — delivery, longer hours, a specific product — that is your next Google Business Profile post or promo, and a prompt to check whether your own listing has the same gap. The goal is not a folder of screenshots. It is one decision made a week earlier than you would otherwise have made it.

Frequently asked questions

Is it legal to check a competitor's Facebook ads in the Philippines?

Yes. The Meta Ad Library is a public tool Meta built so anyone can see the ads a Page is currently running in a given country, including the Philippines. No login is needed and browsing it manually is normal, permitted use. Meta's rules prohibit automated scraping of its platforms, not a person looking at the public ad library.

Can a small business get in trouble for monitoring competitors online?

Not for reading what is public. You can get in trouble if you go further: using a fake account to get into a private group, running a bot or script to copy pages automatically (which needs Meta's express written permission under its Automated Data Collection Terms, and breaches most platforms' terms of service), or collecting and storing personal data about identifiable people without a lawful basis under the Data Privacy Act.

Does the Data Privacy Act apply to information that is already public, like a Facebook post or a Google review?

It can. RA 10173 governs how you collect, use and store personal data, not just where you got it. Reading a public review is fine. Building and keeping a database of reviewers' names, photos and contact details for your own marketing is a processing activity the National Privacy Commission treats seriously. This routine never requires it.

Can I see how much a competitor spends on Facebook ads?

No, not for ordinary business ads. Meta Ad Library publishes spend and reach figures only for political and social-issue ads. For a normal sale or promo you can see the creative, the platforms it runs on and how long it has been live — a long-running ad is a reasonable hint that it is working for them — but not the peso amount.

What is the difference between Google Alerts and the Meta Ad Library?

Google Alerts scans pages Google indexes — news, blogs, articles — and emails you when a name you track appears. It largely misses social media and paid ads. Meta Ad Library is the opposite: it is Facebook and Instagram's own record of currently running ad creative, and it will not surface an organic post or a news article about the competitor.

Can I just ask ChatGPT to research my competitors for me?

Use it to summarise what you have already gathered, not to find it. General AI chat tools do not have reliable live access to a specific competitor's current ads or latest reviews, and they can fill gaps with guesses. Visit the Meta Ad Library and the Google listing yourself, paste your notes in, and ask for a short brief. Never paste personal details about identifiable people.
