Competitor monitoring after OnWebChange: watching rival pages by meaning
Pricing, landing and changelog pages change all the time. Rules written as sentences cut the noise and survive redesigns.
By ClaudeGPT Si Newsroom, Editorial team··3 min read
OnWebChange competitor monitoring is a common setup in SEO and marketing teams: a tracker on each rival's pricing page, another on their feature list, a few on landing pages that keep getting rewritten. It is cheap and it works, right up to the point where the alerts stop telling you anything. This guide covers where that setup strains and how to rebuild it around what changed rather than where it changed.
What teams track on competitor sites
The pages that matter for search and positioning tend to be the same across industries:
- Pricing pages. New tiers, changed limits, a free plan that appears or vanishes.
- Feature and comparison pages. Claims you may need to answer in your own content.
- Landing pages for your target keywords. New headings, new FAQ blocks, new structured content that may be aimed at answer engines.
- Changelogs and release notes. Launches that will show up in search a week later.
- Careers pages. Hiring for a new market or product line.
OnWebChange handles each of these with a tracker per page, a CSS selection for the part you care about, and keyword or number rules to filter noise. Standard and Turbo plans add tracker groups, history and a highlighted difference report, which helps when you are reviewing a rival's copy changes over time.
Where the setup strains
Marketing pages change constantly, and most of those changes are irrelevant. A competitor tests a new hero image, rewrites a testimonial, rotates a banner. With selector and keyword rules you get two kinds of failure:
- Noise. The selected block changes for reasons you do not care about, so the alert fires anyway.
- Silence. The site is redesigned, the selector no longer matches, and the tracker quietly stops seeing the part you wanted.
The second one is worse for competitive work, because you only find out when someone else spots the change first.
Rebuilding it around meaning
AyeWatch replaces the selector and keyword rule with a sentence that says what matters. A few examples for a competitive watchlist:
| Page | Rule |
|---|---|
| Rival pricing page | "Alert me when a plan price, a plan name or a usage limit changes." |
| Rival landing page for a target keyword | "Tell me when they add a new section, FAQ or comparison table. Ignore image and testimonial swaps." |
| Rival changelog | "Notify me when they ship a feature related to reporting or exports." |
| Rival careers page | "Let me know when they post a role in a new country." |
AyeWatch checks each change against the rule and sends a short written summary when it matches. Because the rule does not point at a page element, a redesign does not break it. One webpage monitor can also hold several URLs under one rule, so all five competitors' pricing pages can share a single sentence.
Watching beyond the page
Competitor moves do not only happen on their own site. AyeWatch also runs topic monitors across news, blogs, forums and social sources such as X, Reddit, YouTube and LinkedIn. A topic like "announcements or reviews mentioning [competitor] and a new pricing model" catches coverage that would never show up in a page tracker.
Getting alerts to the team
On every plan, alerts arrive as push notifications in the AyeWatch apps and in the in-app feed. Paid plans add email, a daily digest email, Slack, Discord and signed webhooks, chosen per monitor. A common pattern is pricing changes to a Slack channel and landing-page changes in the daily digest for the content team.
Cost and what stays on OnWebChange
AyeWatch Pro is $9 a month and Pro+ is $19 with the fastest ASAP checks. Usage is counted in monitoring credits, and the app shows the expected credits per day before you save a schedule. For most competitor pages, daily or hourly checks are plenty.
OnWebChange is still the cheaper tool, from 0.89 euros a month, and it tracks PDFs directly. If you watch a rival's downloadable price list or spec sheet in PDF form, keep that tracker where it is.
