Get an Alert When Text Appears on a Website
Sometimes the change you are waiting for is a few words: “registration open”, “now hiring”, “applications closed”, a product name on a retailer's page, or your company's name on a list. RivalPeek.io watches a page and alerts you when the text you name appears, or when it disappears. No selectors or code needed.
Rules you can type
- “Tell me when the words ‘registration open’ appear.”
- “Tell me when ‘sold out’ disappears.”
- “Alert me if ‘Model X2’ appears on this page.”
- “Tell me if our company name is no longer listed.”
- On a list page: “Tell me about new entries mentioning our brand.”
Appears, disappears or new entries
These are three different questions. Appears fires once the phrase is on the page. Disappears fires once it is gone, which is often the better rule for availability: waiting for “sold out” or “waitlist full” to vanish. New entries mentioning works on lists, such as news, notices or listings, and reports each new entry that contains the word. Pick the one that matches your situation; the review shows which rule was built.
How it works
- Paste the page address and write the phrase in quotes in your sentence.
- Check the preview: whether the phrase is on the page now, and which part of the page is searched.
- Approve. If the phrase is already on the page, the first check sends the alert straight away, so check the preview first.
- When it matches, the alert names the phrase and what changed on the page, with a link to the source.
Choosing a phrase that works
Use wording the site is likely to keep. “Registration is now open for the 2027 intake” may be rewritten; “registration” plus “open” is more robust. Avoid phrases that also appear in menus, footers or cookie banners, or narrow the watch to the section that matters. If the phrase is inside an image, a video or a downloadable file other than a supported PDF, it cannot be read.
Limits
- Text revealed only by clicking a tab, a “show more” button or a form.
- Pages behind a login, and search results with no address of their own.
- Very short-lived text that appears and disappears between two checks.
- Sites that block automated visits; the review tells you when a page cannot be read.
Which plan fits
Starter covers 20 pages checked every hour with email alerts, which suits a short list of pages. Pro covers 150 pages checked every 15 min and adds Slack and webhook alerts. Business covers 500 pages checked every 15 min for larger watchlists. For time-sensitive phrases like “registration open”, the shorter interval matters more than page count.

Choose your monitoring capacity
Choose a plan for the pages you need to follow. Starter costs USD $19/month for 20 pages, with ordinary checks every hour. Annual billing is USD $190/year. Pro costs USD $39/month for 150 pages, with ordinary checks every 15 min. Annual billing is USD $390/year. Business costs USD $99/month for 500 pages, with ordinary checks every 15 min. Annual billing is USD $990/year. These are scheduled checks, not a live stream; availability and the check queue can affect when a result arrives.
Pages requiring protected checking use a separate allowance and a slower schedule. Access is not guaranteed, and some sites block automated visits. Start with a representative public URL and review the result before expanding your watchlist.
Frequently asked questions
Is the match case-sensitive?
No. “Sold Out” and “sold out” match the same way. Spacing and wording still matter, so keep the phrase short and distinctive and check in the preview whether it is found today.
Will it alert me again every check while the text is there?
No. You get one alert when the condition is met. The watch then stays quiet until you re-arm it from the watch page, so a phrase that stays up does not send repeated emails.
Can I look for a pattern, such as any date or code?
Yes. Advanced rules can use a regular expression; the review shows what it matches. For most needs a plain phrase is easier to maintain.
Can it find the text across a whole website?
No. It watches the pages you add, one page per watch. It does not crawl or search a whole site for the phrase.
