How to monitor competitor websites for changes
Competitor websites change quietly: a new pricing page, a comparison page, a new industry landing page. You do not need a enterprise intelligence platform to notice. You need a repeatable weekly process.
1. Decide what is worth watching
Do not track every blog post. Start with pages that change how a buyer compares you:
- Pricing and plans — price, packaging, limits, discounts.
- Product and feature pages — new capabilities, positioning, integrations.
- Comparison pages — “vs”, “alternatives”, and competitor-specific pages.
- Industry pages — a new vertical or customer segment.
- Homepage headline — a repositioning signal.
For a small SaaS team, five competitors is usually enough. More than that becomes a reading project instead of a decision tool.
2. Use the public sitemap as your index
Most websites publish a sitemap.xml that lists their pages and last-updated dates. Open https://their-domain.com/sitemap.xml. If it is an index, open the child sitemap for pages or products.
The dates are not perfect: some sites update every date on every deploy, and some never update them. Treat the sitemap as a map, not as proof. The useful signal is a page that was not there last week.
You can try this on any site with our free website change checker. It lists pages dated in the last 30 days and explains the limitations.
3. Keep a small weekly log
Once a week, write down only the changes that could affect a buying decision:
- What changed? Use the URL and a short quote or page title.
- What does it likely mean? Mark inferences as inferences.
- Do we need to respond? Ignore, watch, or act.
A template keeps this from becoming a 20-tab research session. We published a weekly competitor briefing template you can copy.
4. Separate weekly changes from daily price alerts
Weekly sitemap comparison is good at catching new pages. It is not good at catching a number changing on an existing pricing page. For pricing, you need to compare the page text itself. Our guide to pricing-page tracking covers that workflow.
5. Automate the repetitive part
The repetitive part is not the judgment. It is remembering to check, storing last week’s version, and noticing the difference. That is what Competitor Radar does: it checks up to five competitors every week and sends one short email with the pages that appeared or disappeared.
If you need more than five competitors, daily price-page alerts, or a broader watchlist, see Pricing.
Start small
Pick five competitors. Add their domains to a weekly reminder. After four weeks, you will have a much better picture of how your market moves than a one-off research sprint would give you.
