Why these checks exist
Picture a shop on a busy high street. During the night cleaning, a “Closed” sign is accidentally left hanging on the door. You only notice in the evening, because nobody came in all day.
That sign exists online too. It is called noindex, and it tells Google not to show the page in search results. After a website update it is quickly set by accident, and the stream of visitors from Google dries up, often unnoticed for weeks.
A live24h SEO check looks in regularly to see whether such a sign is hanging on your most important pages, and gets in touch as soon as something changes.
What gets checked
Four technical details decide whether a page may appear in Google:
| Signal | In plain words |
|---|---|
robots.txt | The house rules of your domain: is Google allowed to open this address at all? |
<meta name="robots"> | A short note in the page header. Does it say noindex? |
X-Robots-Tag | The same instruction, but sent by the server and invisible in the browser. Easily missed after CDN changes. |
<link rel="canonical"> | The original reference of a page. Is your product page suddenly pointing at a staging environment? |
The feature page SEO monitoring shows what this looks like in the app, with screenshots.
What you need beforehand
- A publicly reachable address. Pages behind a login or on a local machine cannot be checked.
- A plan that includes SEO checks. How many addresses each plan covers is listed on the pricing page .
- A confirmed notification channel, email for example. Without one the check still runs, but the message never reaches you.
You do not need technical background knowledge. The assistant comes preconfigured so that in most cases you only enter the address and confirm.
Step by step to your first check
In the dashboard you will find SEO as its own area next to your other checks. “Add SEO check” opens an assistant that guides you through these stations:
- Target. Enter the exact address that should appear in Google, complete with
https://and path, for examplehttps://www.your-company.com/pricing. live24h suggests a display name from the address. If a sitemap is available, the assistant offers your most important pages for selection straight away. - Signals. All four signals are already switched on. That is the right choice for almost any page; at least one has to stay active.
- Expectation. Here you define what normal looks like: the page should appear in Google (the usual case) or explicitly should not (login and account areas). For the original reference, “points to this address” is the common setting.
- Frequency. How often the check runs. Recommendations follow in the next section.
- Alerts. The first 24 hours run in observation mode: live24h learns what is normal on your page and stays quiet. Please leave that switched on. After that you choose what you want to hear about, such as a new
noindex, a block inrobots.txtor a changed original reference. - Summary. Everything at a glance once more, then create the check.
Which pages are worth it
Not every subpage needs monitoring. A small selection of the pages that carry your business is the sensible choice:
| Page | Why |
|---|---|
| Home page | The most important entry point from search |
| Main service or product page | This is where revenue comes from |
| Pricing, checkout or contact page | Enquiries and deals happen here |
| Large category or overview pages | They distribute search traffic to many subpages |
| Login or account area | The reverse case: it should not show up in Google |
Rule of thumb: monitor the ten to fifty most important pages properly rather than hundreds. A long list makes the overview restless without adding certainty.
How often to check
SEO details do not change by the minute. Checking more often is therefore not better, it only puts load on your site.
| Interval | When it makes sense |
|---|---|
| Weekly | Very static pages such as legal notice or terms |
| Daily | The standard for most important pages |
| Every 12 hours | Key product pages, frequent CMS changes |
| Every 6 hours | The maximum, only for your very top addresses |
For the critical hours after a website update there is also deployment watch: one click in the detail view and live24h checks hourly instead of daily for 24 hours. After that it switches itself off again.
Reading the results
Every run ends with a short verdict:
| Verdict | Meaning |
|---|---|
ok | Everything as expected |
warning | Something changed and should be looked at |
critical | The page is no longer findable the way you wanted |
fetch_failed | The address did not answer at all |
blocked_by_waf | A firewall turned the check away |
rate_limited | The server throttled the check |
On top of that comes the baseline: the state you mark once as “this is correct”. Every later run is compared against it, and the message shows exactly the changed line with the old and the new value. So you do not have to hunt for the difference yourself.
Common stumbling blocks
- “I just created a check and got an alert immediately.” The 24 hour observation mode is probably switched off. Please leave it on, the first runs establish the point of comparison.
blocked_by_waf. Your firewall is not letting our check through. How to allow it in common firewalls is described on our bot page .fetch_failed. The address is not answering at all. Open it in your own browser first: if that fails too, it is an outage and not an SEO problem. The uptime check covers that, see quickstart .rate_limited. The server throttled us. That usually resolves itself on the next run; if it persists, choose a longer interval.- Several original references on one page. That is a genuine error in the page source which your agency or development team should fix. Otherwise Google decides for itself which one counts.
- Planned maintenance. Set the check inactive in the detail view for a while instead of clicking messages away.
If your page builds its content with JavaScript
Some websites deliver an almost empty shell and only fill it in the browser. If the original reference or the noindex setting only appears at that second stage, a simple check will not find it.
For this case JavaScript rendering can be switched on per check: live24h then builds the page like a browser and checks afterwards. The option is available from the Business plan and runs on a monthly allowance whose remaining balance is shown directly in the assistant.
What SEO checks are not for
- Availability. Whether your website is online at all is answered faster and more often by the uptime check.
- Search positions. Where you rank for a search term belongs to a rank tracker, not to monitoring.
- Full technical audits. Image descriptions, load times or mobile friendliness across the whole domain are the job of an audit tool. SEO checks are the early warning for the pages that carry your business.
