Let Me Know When Review: AI Website Monitoring Done Right?
I’ve been in the SEO and digital marketing game for... well, let's just say long enough to remember when checking a competitor's site meant manually opening 15 tabs every morning with a lukewarm coffee in hand. We’d squint at the screen, trying to spot if they'd changed a title tag or updated their pricing. It was tedious. It was inefficient. And we missed stuff. A lot of stuff.
So when a tool like Let Me Know When pops up on my radar, claiming to be an “AI-Powered Website Monitoring” platform, my inner cynic and my inner nerd both sit up and pay attention. The cynic asks, “Is ‘AI’ just the new buzzword for a simple notification script?” But the nerd, the one who loves traffic data and a good competitive edge, whispers, “What if this is actually it? The easy button?”
So, I took a look. And I have some thoughts. Spoilers: it’s pretty cool.

So, What Is Let Me Know When, Actually?
At its core, Let Me Know When is a digital tripwire. You tell it which websites (or even specific parts of a website) to watch, and it pings you when something changes. Simple enough, right? But that's like saying a smartphone is just a device for making calls. The real magic is in the details.
This isn’t just about a website being up or down. We’ve had uptime monitors for ages. This is about the granular, nitty-gritty changes that can make or break a strategy. Think of it less as a simple alarm system and more like a dedicated security guard for your digital turf. A guard who not only tells you someone's at the door but also gives you a full dossier on them before they even ring the bell. It promises “Intelligent Insights, Effortless Monitoring,” and from what I’ve seen, it gets pretty close.
Why Website Monitoring Is No Longer Optional
You might be thinking, “Okay, sounds neat, but do I really need this?” In my experience, yes. If you’re serious about your online presence, manual checks just don’t cut it anymore. The digital space moves way too fast. Here's who I think this is for:
For the SEO Geeks Like Me
I once lost a top SERP position because a competitor slyly tweaked their title tag and H1s over a weekend while I was blissfully offline. I learned my lesson the hard way. With a tool like this, you can get an alert for:
- On-page SEO changes: Get notified if a rival changes their meta descriptions, header tags, or body content.
- `robots.txt` or sitemap updates: Know immediately if a competitor is trying to block or allow certain crawlers. It’s a sneaky but effective way to see their next move.
- New backlinks... or lost ones: While dedicated backlink tools exist, you can even monitor a journalist's profile page to see when they link out to a new story (or a competitor!).
For the E-commerce Hustlers
If you're in e-commerce, you live and die by price and availability. Let Me Know When can be your secret weapon. Imagine getting instant alerts when a competitor drops their price on a key product, or when that hot-ticket item your customers want is finally back in stock on your supplier's site. You can monitor for price changes, “out of stock” to “in stock” updates, and even new customer reviews on product pages. That’s actionable intelligence you can take straight to the bank.
For the Content Marketers and Digital PR Folks
Struggling for content ideas? Set up monitors on top industry blogs or news sites. When they publish a new piece, you get an alert. This allows you to be one of the first to react, either by writing a response piece, sharing it with your own take, or just staying ahead of the curve. You can also track journalist pages on platforms like Muck Rack or even their company bio page for new articles, giving you the perfect, timely reason to reach out.
The ‘AI’ Part: Gimmick or Game-Changer?
Let's be real, the term 'AI-powered' gets thrown around more than a frisbee in a park these days. Often, it's just marketing fluff. Here, the “AI” seems to refer to their “AI Workflows.” This isn’t just about detecting that a change happened, but providing context on what the change means. Instead of just a notification that “the code on this page has changed,” an AI workflow could potentially be configured to understand that a price has dropped by 15%, or a specific keyword has been added to the H1 tag.
This is where the paid plans start to make a lot of sense. The free plan doesn't include these workflows, so you're getting the basic change detection. But with the paid tiers, you unlock the ability to build these smarter, more contextual alerts. For a business, that's where the real ROI is.
Let's Talk Money: A Look at the Pricing Plans
Alright, down to brass tacks. How much does this digital watchdog cost? They have a flexible structure that caters to everyone from a casual hobbyist to a full-blown agency. I’ve always appreciated a company that offers a free-forever plan, even if it’s limited. It shows confidence in their product.
| Plan | Price | Best For | Key Features |
|---|---|---|---|
| Free | $0 /month | Trying it out, very small projects | 10 websites, 2 checks/day, Email notifications |
| Starter | $9.99 /month | Personal use, small businesses | 20 websites, 4 checks/day, 1 AI Workflow, Slack notifications |
| Advanced | $19.99 /month | Power users, serious marketers | 30 websites, 6 checks/day, 5 AI Workflows |
| Premium | $89.99 /month | Professionals & Agencies | 50 websites, Hourly checks, 10 AI Workflows, Premium support |
My take? The free plan is perfect for dipping your toes in. Track your own blog and maybe a couple of top competitors to see how you like it. The Starter and Advanced plans are the sweet spot for most freelancers and small-to-medium businesses. The jump to Premium is steep, but for an agency managing multiple high-value clients where an hourly check could mean thousands of dollars, it's a no-brainer.
The Good, The Bad, and The Realistic
No tool is perfect. Let's be balanced. The biggest pro is the sheer breadth of its capabilities. From SEO to e-commerce to job hunting, the use cases are massive. The interface looks clean, and the inclusion of Slack notifications is a huge win for team workflows. I live in Slack, so email alerts often go to a graveyard folder.
On the flip side, the main con is that the truly powerful stuff, the AI Workflows and higher check frequencies, are locked behind a paywall. Honestly, that’s to be expected. You can't expect a company to offer hourly checks on 50 websites for free. The free plan is a bit limited with only two checks per day—a lot can happen in 12 hours. It's more of a 'try before you buy' than a long-term free solution, and thats okay.
Frequently Asked Questions (The Stuff I'd Ask)
1. Can Let Me Know When track websites that require a login?
This is a common question for monitoring tools. Based on how these platforms typically work, monitoring content behind a login is complex and often not supported out-of-the-box due to authentication requirements. For publicly accessible pages, however, it works perfectly.
2. How exactly do the "AI Workflows" work?
While they don't give away the secret sauce, an AI Workflow is likely a system where you can set more intelligent triggers. Instead of just "alert me on any change," you could set it to "alert me only if the text 'out of stock' is removed" or "if the price is now below $50." It adds a layer of if-then logic to make your alerts much more specific and less noisy.
3. Is the free plan good enough to get started?
Absolutely. It’s a great way to understand the mechanics and monitor a few non-critical pages. It lets you see the value firsthand before you commit any money. I'd recommend it for tracking your own site for unwanted changes or keeping a casual eye on one or two main competitors.
4. What's the difference between a check and a monitor?
A "monitor" is the website or URL you're tracking. A "check" is each time the tool's bot visits that URL to see if anything has changed. So if you have 1 monitor with 2 checks per day, the tool will visit that page twice in 24 hours to look for updates. Your plan's total checks are distributed across all your monitors.
So, Is Let Me Know When Worth Your Time?
After looking it over, my verdict is a solid yes. For me, the value is clear. In a world where a single, unnoticed change on a competitor's website can cost you rankings, sales, or opportunities, automated monitoring isn't a luxury; it's a necessity. Let Me Know When provides an accessible, powerful, and scalable way to do it.
It’s a tool that can save you time, give you a competitive edge, and maybe, just maybe, prevent that sinking feeling in your stomach when you realize you missed something important. And for this old-school SEO, that’s worth a whole lot.
