Competitor Monitoring Agent

Weekly autonomous scrape of competitor sites, ads, pricing, reviews, and social — diffed against last week, summarized in Slack.

Setup difficulty: advanced

The Problem

Founders and marketing leads should know when a competitor changes pricing, launches a new service, or starts running new ads — but nobody checks consistently. An agent does it weekly: hits each competitor's site, ads transparency page, review platforms, and key social accounts; diffs the changes; summarizes what's new in plain English with links. 5 minutes of reading each Monday replaces 2+ hours of manual checking that nobody actually does.

Workflow Steps

1

Define the watchlist

5-10 competitors max. For each: pricing page URL, blog/news URL, Facebook Ads Library link, Google reviews URL, key social handles. More = noise.

2

Set up scrapers

Firecrawl or Apify for site scraping. Meta Ad Library has a public API. Google Reviews via Outscraper or Birdeye. Schedule weekly via n8n or Make.

3

Diff against last week

Store last week's snapshot. New scrape = compare → extract: new pages, changed pricing, new ad creatives, new 1-star reviews, employee announcements.

4

Summarize the meaningful changes

Feed diffs to GPT-4: 'From these changes across [competitor], identify the 3-5 strategically meaningful items. Ignore minor wording tweaks. Flag any pricing or new-product changes loudly.'

5

Deliver to Slack every Monday

Single channel post: per-competitor section, bullet list of changes, links to evidence. Tag the marketing lead on anything tagged 'pricing change' or 'new product'.

6

Quarterly trend report

Aggregate the weekly diffs into a quarterly view: who's most active, who's changed positioning, what themes are emerging. Useful for board / strategy reviews.

Weekly Diff Summary Prompt
You are a competitive intelligence analyst. Given these scraped changes from {{competitor_name}} this week vs. last week, identify the 3-5 strategically meaningful items. Ignore minor wording tweaks, footer changes, and routine blog cadence. Flag pricing changes, new product/service additions, hiring announcements (especially senior leadership), and shifts in positioning loudly.

Orchestration pattern

Single agent with function-calling: one LLM with a defined toolbox (CRM, calendar, knowledge base) decides which tool to invoke at each turn. Easiest to debug; appropriate for most well-scoped SMB workflows.

Failure modes & mitigations

Where this workflow tends to break in production — and what to put in place before you ship it.

Drowning in noise from minor changes

Mitigation: Strict prompt instruction to ignore wording tweaks; only HIGH-priority items get @mentions.

Scraper breaks silently

Mitigation: Health check that requires non-empty diff every other week; alert on suspicious zeros.

When NOT to Use This

Skip if you only have one or two competitors and you already know them well. Skip if you're a category creator with no direct competitors. Don't scrape sites that explicitly disallow it in robots.txt.
