What is website change monitoring?
Website change monitoring checks a page on a schedule and tells you when its content changes. With Context.dev you create a monitor for a page, a sitemap, or a site’s key pages, and receive a signed webhook each time a run detects a change.
Can I monitor Reddit for keywords?
Yes. Create a page monitor for a subreddit or a Reddit search page, and each run is compared with the last one. Dench CRM pulls new Reddit posts every hour through Context.dev to reply to leads while they are fresh.
How often can a monitor check a page?
You set an interval schedule, such as every 6 hours, when you create the monitor. You can change the schedule later or trigger an extra run whenever you need a fresh check.
How much does website monitoring cost?
Each run costs 1 credit for a page or sitemap target, or 10 credits for an extract target. The free plan includes 10 monitors and 1,000 credits every month.
