Your competitors are publishing while you're auditing.

New posts, new landing pages, quiet rewrites of the pages that outrank you — it happens constantly, and checking by hand means you find out weeks late. Page Deltas watches your whole competitive set and tells you the moment they ship something, so your content team reacts in hours instead of stumbling on it next quarter.

Their content calendar, in your feed.

Everything you need to keep pace with a competitor's publishing — and react before they rank.

Auto-discover every new page

Point Page Deltas at a competitor's sitemap and get alerted the moment they publish a new URL — a blog post, a landing page, a programmatic rollout. No manual crawling.

Catch the rewrites, too

Competitors refresh top pages to defend rankings. Monitor the URLs that matter and get an AI summary when the content is substantially reworked — not just a vague “something changed” ping.

AI summary of what changed

Every content change comes with a plain-language summary of what was added, removed, or reworded, so you can read intent without re-reading the whole page.

API & webhook delivery

Pull changes via API tokens or push them through signed webhooks straight into your dashboards, BI, or content workflow. Slack, Teams, Discord, and email too.

Sitemap discovery

Auto-discover every new page a competitor publishes.

Most sites list every page in a sitemap.xml. Page Deltas watches it and alerts you whenever a new URL appears — giving you a live view of a competitor's entire publishing cadence without crawling the site yourself. It's the fastest way to see what they're building and which topics to target before they rank.

  • Alerts when new URLs appear in a competitor's sitemap.xml
  • See their whole publishing cadence — every new post, page, and rollout
  • Sitemap monitors don't count against your monitored-URL limit
  • Spot content gaps and emerging topics to target first

What you'll catch.

From a single new post to an at-scale programmatic launch — nothing ships unnoticed.

New blog content

Know the day a competitor publishes a post, so you can respond or out-cover the topic while it's fresh.

New landing pages

Catch new use-case, comparison, and campaign pages as they go live — and the keywords they're chasing.

Content rewrites & refreshes

Get alerted when a ranking page is substantially reworked, the move competitors use to hold position.

Pillar & hub expansion

See when rivals build out topic clusters and internal-linking hubs around a theme.

Programmatic rollouts

Detect templated, at-scale page launches — location, integration, or feature pages appearing en masse.

Pricing & product edits

Catch on-page changes to the commercial pages where messaging and conversion really matter.

Built for tool-savvy teams

Pipe changes into the stack you already run.

SEO and content teams live in dashboards, crawlers, and BI. Page Deltas fits in rather than adding another tab: pull detected changes via the API or push them through a signed webhook into whatever you've built — Looker, a Google Sheet, a Slack workflow, your own content log.

  • Programmatic API tokens for pulling changes into your stack
  • Signed webhooks for real-time push into your own systems
  • Structured payloads you can route, store, and report on
  • Plus Slack, Teams, Discord, and email for the humans

03

React before they rank

New pages and rewrites land in your feed with an AI summary, so your team responds in hours, not weeks.

Frequently asked questions

How do I track when a competitor publishes new content?
Point Page Deltas at their sitemap and we'll alert you when new URLs appear — so you see every new post and page without crawling the site yourself. It's a live view of their publishing cadence.
Can I detect when a competitor rewrites an existing page?
Yes. Monitor the URL as a normal page and you'll get an AI summary whenever the content is substantially changed — the refreshes competitors use to defend their rankings.
Can I pull changes into my own tools via API or webhook?
Yes — this is a core reason SEO teams pick us. Pull detected changes with programmatic API tokens, or push them through signed webhooks into dashboards, BI, or a content workflow. Structured payloads make it easy to route, store, and report on.
How many competitors can I track affordably?
Sitemap monitors discover new URLs and don't count against your monitored-URL limit, so you can watch many competitors' publishing cadence cheaply — you only spend URL quota on the specific pages you choose to monitor closely.
Where do alerts go?
Slack, Microsoft Teams, Discord, email, or a signed webhook / API — whatever fits how your team and tools already work.

Never get out-published again.
