MonitorMojo vs Spreadsheets: Why Tracking Website Health in Sheets Fails

Spreadsheets are good at storing information that someone knows and enters: client names, domain names, hosting provider details, SSL certificate renewal dates at the time they were entered, notes from past site reviews. They are useful as a reference document when you need to look up a piece of information you already know.

For client portfolio management — keeping track of who owns what, where sites are hosted, and what is coming up for renewal — a spreadsheet is a reasonable tool. It works well as a manual record-keeping system when the information in it is accurate and current.

For a small practice with a few clients and a disciplined update habit, a well-maintained spreadsheet can carry a monitoring workflow for a while. The problems emerge at scale and when the entries get out of date.

The fundamental problem with spreadsheets as a monitoring tool is that they do not check anything. The SSL expiry date in a spreadsheet is accurate as of when it was entered. If the certificate was renewed, auto-renewed with a different expiry, revoked and reissued, or changed to a different certificate type, the spreadsheet still shows the old date until someone manually updates it.

Spreadsheets also cannot surface response time, security header status, current reachability, or HTTP status codes. These signals are not things you can check and enter manually with any regularity — there are too many and they change too dynamically. A spreadsheet can tell you that a site was reachable as of last Tuesday when someone checked. A health check tool tells you whether it is reachable right now.

For agencies with growing portfolios, spreadsheet maintenance also becomes a significant overhead. Keeping renewal dates current, noting which sites have been checked recently, and tracking issues across many client entries requires discipline that is hard to maintain consistently when there are always more urgent things to do.

A website health check tool verifies the actual current state of a website, not what was recorded at some point in the past. SSL certificate status is checked from the live certificate installed on the domain right now — not from a renewal date someone entered in a spreadsheet. Response time is measured from an external server at the moment the check runs. Security headers are read from the actual server response.

This means health check results are always current, without manual update effort. A check run today reflects today's reality. A spreadsheet reflects when it was last updated, which may be quite some time ago.

Health check results also give you actionable output. A spreadsheet note that says 'SSL renewal due June' does not tell you whether the certificate has been renewed or not. A health check result that shows the certificate is valid and expires in August tells you exactly where things stand.

Spreadsheets and health check tools are complementary rather than mutually exclusive. A spreadsheet is useful for tracking client information, hosting credentials, notes from client conversations, and administrative context. A health check tool provides the live technical data that the spreadsheet cannot maintain accurately.

The practical combination for most agencies is: use a spreadsheet (or a simple CRM or project management tool) for client administrative records, and use a health check tool for the actual technical monitoring workflow. Run health checks on a schedule, and use the results to update relevant fields in your client records rather than trying to maintain them manually.

MonitorMojo provides the health check side of this workflow — current, reliable technical data on reachability, SSL, response time, security headers, and domain risk — without replacing the client management tools your team already uses.
