Use Data Or Be Used By Data!

The November 9 issue of Seotistics is here for you!

Last week we saw some nice examples with vibecoded apps, among my favorite activities today.

What about having other people use them?

Well, this is another issue that we'll address today!

📣📣 Important Announcements 📣📣

🪎 Black Friday sales will start around November 27, warm up your wallets!

Also updating finally my products and everything else, you will see 👀

I will speak at MeasureCamp Zurich (November 22), my last event for 2026 (too tired).

And for 2027, don't forget about Found Conference Tokyo - 18-19 Feb 2027 (Super Early Bird active now).

Seotistics News

From November 2 to November 9:

Microsoft Clarity adds Agentic Analytics -> how would agents interact with your website
GA4 launches Data Manager in beta -> showing streams and connectors
BigQuery Graph and Studio rename of options
Anthropic adds IP allowlist -> you can restrict which IPs use Claude, ideal against API leaks
GTM update how page_view is calculated with back/forward
GSC click spikes (only some properties)

The previous weeks were far more interesting but I confess I am hyped up by the BigQuery changes, Clarity and Data Manager.

And if you like modern stuff, go check my new article on Python scraping libraries.

This is all nice food for your agents in case you need to retrieve information online.

Where To Run An App

I've previously shown my agent setup where I have a lot of personal apps, running inside my VPS.

For context, a VPS is a share of a computer you rent.

For my own apps where only I have access, there isn't much to understand.

Tailscale makes sure the access is restricted to my own pre-approved devices.

Common examples include:

your control panel
reports
crons, scripts, automation

All of this is to run your business and there is no need to grant access to the external world.

What if you built an app for a project and your clients need access? It's a different story now!

Say, I have to build a robots.txt checker to see if a website can be eligible for LLMs...

we need another approach.

Making An App Available Easily

There are many solutions, I will introduce you to one of the most recent ones: Cloudflare Workers.

The service is straightforward, you rent a small process running inside Cloudflare and you put your app there.

This approach is one of the easiest, not the best, but an easy one to practice.

Once it's done, you get a working link to the app you can share around.

This assumes you already know how to (vibe)code an app yourself.

In case, help yourself with an LLM and give this issue as the material 👀

Then, you have different options:

have a dedicated (sub)domain for it
host it on your website via iframe
other options I don't want to bore you with

I still have to evaluate some risks, so my website isn't on Cloudflare yet.

I opted to embed an iframe with the tool instead.

You can test it yourself here for fun, this app tests if your website is eligible for AI results/interactions.

Still something to improve but this is a nice beta built in less than 3 hours!

An example on the CNN website produced this result:

Reminder: this isn't 100% done, it's an example to show you how to quickly make it available.

If you have read my previous LI post, you know that there are 3 layers to AI visibility.

Security Measures

This is just a quick example I built but there are some basic guardrails to avoid abuse.

For example:

validating the text people write inside the bar
stopping excess requests

For actual commercial use cases, you need to ask a true engineer.

But for simple use cases like the ones we often do, you can DIY.

You get to learn a LOT about systems and you will be unstoppable.

Abstraction and understanding systems is what humans do that AI needs help with.

Flashback: How To Build Stuff

You may wonder what is the most optimal setup to produce and work.

Well, let's go by degrees as usual:

ChatGPT/Claude (the interface), this is the lowest level
Claude Code/Codex, much better already
Agent orchestration, you have a system trained on your needs

The last approach can be achieved with tools like Hermes Agent or Grokbot.

I prefer the former because it's open source, I love the community and I don't have to support Elon 💀

After months of back and forth, it became extremely helpful with my work.

As I often say, the key of LLMs is to nurture the right context and discard what's unnecessary.

Speaking of which, I have been recently mixing my DeepSeek usage with Claude Code (subscription).

Folks, the results are amazing here 😎

The only issue is that using /usage in Claude Code shows potential API costs and NOT what you actually spend with an active subscription.

Check the bottom of the newsletter to find the resources you need to get started.

What's Next

Depending on whether you are an analyst or marketer, you have some work to do.

If you haven't fully learned how to play with LLMs, this is the right time to explore beyond Claude Code.

People say "marketing careers are becoming more technical"... but the message comes from people without technical skills 💀

So yes it's partially true but you need to get first-hand experience AND understand marketing.

In the last 3-4 months I:

created a very successful content system, helping me prepare the content you are reading
learned a LOT more about servers, deployment and apps
built some nice things I will disclose soon
worked on a lot of designs and material

And trust me, anyone can do it, the only limits are time and imagination.

Next week you will see some cooler stuff (as usual) + new content on Seotistics 😎
