When it detects a change, it sends an email, phone notification, Slack or SMS alert, usually with the changes highlighted. Unlike an RSS feed, which only shows new posts, a monitor can watch any part of any page, including old pages that get quietly updated.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Best_webpage_monitoring_services\"><\/span>Best webpage monitoring services<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul>\n<li><strong><a href=\"https:\/\/visualping.io\/\" target=\"_blank\" rel=\"noopener\">Visualping<\/a>:<\/strong> paste a URL, draw a box around the part you care about, and get alerts with before-and-after screenshots.
