Yes, it covers the things that quietly undo campaign work. Scheduled [Lighthouse audits](https://ohdear.app/features/lighthouse-seo-monitoring) track Core Web Vitals and SEO scores over time, the [crawler](https://ohdear.app/features/broken-page-and-mixed-content-detection) catches broken links and dropped sitemap URLs after a content edit, and [uptime checks](https://ohdear.app/features/website-uptime-monitoring) make sure a landing page is actually live when the ad spend hits it. Every client site sits in one dashboard with reports you can hand straight to the client. ### Why would a marketing agency need uptime monitoring at all? Because your work depends on the site being up and fast, and you are usually blamed when it is not. A landing page that is down during a launch burns ad budget, a Core Web Vitals regression after a redeploy quietly drops the rankings you worked for, and a broken link from a campaign email loses the click. Oh Dear watches [uptime](https://ohdear.app/features/website-uptime-monitoring) and [performance](https://ohdear.app/features/lighthouse-seo-monitoring) so a technical problem on the client's side does not read as your campaign underperforming. ### Isn't Search Console or PageSpeed Insights enough for client sites? They are snapshots you have to remember to run, one site at a time, with no alerts. Search Console reports a 404 only after Googlebot hits it, and PageSpeed grades a single page on demand. Oh Dear runs the [checks](https://ohdear.app/features/lighthouse-seo-monitoring) on a schedule across every client site and alerts you when something regresses, so you catch the [broken link](https://ohdear.app/features/broken-page-and-mixed-content-detection) or the speed drop before the next report, not after the client does. ### How does website performance affect my clients' Google rankings? Google uses Core Web Vitals as a ranking factor. Slow-loading pages, layout shifts, and poor interactivity can push your clients down in search results. Oh Dear runs automated [Lighthouse audits](https://ohdear.app/features/lighthouse-seo-monitoring) and alerts you when performance scores drop, so you can fix issues before they impact rankings and organic traffic. ### Can I get automated reports to show clients? Yes. Oh Dear sends [automated monthly reports](https://ohdear.app/docs/features/uptime-and-performance-monitoring#monthly-reporting) with uptime percentages, performance trends, Lighthouse scores, and broken link fixes. You control who receives them: send reports to yourself to review first, or deliver them directly to clients. Either way, they help demonstrate ongoing value and justify maintenance retainers without manual work. ### What happens if a client site goes down during a campaign? We check every minute from multiple global locations. When downtime is detected, you get an [alert within 60-90 seconds](https://ohdear.app/features/notifications) via Slack, email, SMS, or your preferred channel. You'll know about the problem before clients do and have the timeline ready when they ask what happened. ### How do broken links affect SEO and what can I do about them? Broken links signal poor site quality to search engines and frustrate visitors. Oh Dear [crawls client sites daily](https://ohdear.app/features/broken-page-and-mixed-content-detection) and flags dead links, missing images, and mixed content warnings. This is especially valuable after CMS migrations or content updates when links often break silently. ### Can I monitor multiple client sites from one dashboard? Absolutely. Oh Dear is built for agencies managing many sites. You can [organize sites with tags](https://ohdear.app/docs/features/using-tags-on-sites), set different alert recipients per client, and view performance across your entire portfolio at a glance. One dashboard replaces juggling multiple monitoring tools.
