Tips and best practices

To get the most out of the tool, it's worth implementing a few simple rules.

Group URLs by project or client. This will make reporting and task prioritization easier.
Add both the homepage and key subpages. For example, categories, important landing pages, and cart.
Regularly check expiration dates in the domains section. Respond in advance, especially for important brands.
Set your own phrases or code snippets to monitor. Check for analytics code and legal content presence.
Analyze TTFB along with traffic data. Slow pages with high traffic need priority optimization.
Use broken backlink data in your link building process. Ask partners to fix broken links.
Compare the number of ranking keywords before and after major changes to assess impact more easily.
Regularly export data to CSV. Archive important technical changes and site work.

Most common mistakes

Even the best tool won't help if you use it irregularly or only partially.

Adding only the homepage without monitoring key subpages, categories, blog, and landing pages.
Ignoring the Domain section. Not reacting to an approaching domain expiration date.
Focusing only on error codes, without analyzing TTFB and backlink quality.
Not using the text or code monitoring field. Manual verification instead of automated control.

Case study

Imagine an SEO agency serving several dozen clients. Each client has its own domain and a few sites.

Previously, the team monitored site status manually, spot-checking HTTP status, SSL validity, and basic traffic data.

After implementing the Website Monitoring tool, the agency added over 100 client domains to the dashboard. In one view, they saw technical status and domain health.

The first check discovered several domains with expiring dates. Clients renewed them in time.
Broken backlinks from important sponsored articles were also found. Partners quickly fixed the links.
Comparing TTFB revealed a slow server for one of the bigger stores. Migration improved user experience.
Monitoring an analytics code snippet helped detect faulty implementation on several subpages.
With ranking keyword data, the team more easily identified which domains needed immediate content support.

The agency gained a single source of truth about their clients' technical and SEO performance. The team now spends less time on manual checks and more on activities that increase traffic.
