Google Tag Manager
I use Google Tag Manager mainly when data should lead to a practical decision, not just another report. It helps deploy and manage tags, events, and marketing scripts without requiring every small change to go through an application deployment. It makes the most sense when results are reviewed regularly and connected to specific changes on the website or in campaigns.
Google Tag Manager is useful when tag and tracking management should not be managed by feeling alone. Data by itself is not enough, though. The important part is choosing the signals that actually change the next step.
That is why I would not treat Google Tag Manager as a place to visit occasionally for a nice chart. The value appears when the tool becomes part of regular decision-making and someone actually changes content, campaigns, or priorities based on it.
Where it makes sense
It helps deploy and manage tags, events, and marketing scripts without requiring every small change to go through an application deployment.
The practical benefit is that the team does not start from an empty page. It can see what is happening, where the problem is, and where an opportunity may exist.
From report to decision
A report does not move the project by itself. It needs interpretation and a follow-up action. It is better to focus on a smaller set of metrics that clearly influence the next step.
Instead of watching everything, the better questions are: what do we fix, what do we test, what do we stop, and what is worth expanding?
A regular rhythm
Tools like this work best when they are used regularly. A one-time view can reveal a problem, but a trend shows whether the project is actually improving.
That rhythm can be a weekly check, a monthly review, or a review after a larger change. The important thing is that outputs have an owner.
What to watch out for
Analytics is useful only when it is configured correctly. Bad events, missing consent handling, or unclear conversions can lead to very poor decisions.
When Google Tag Manager supports judgment, it is very useful. When it becomes just another dashboard, its practical value drops quickly.

PageSpeed Insights
I use PageSpeed Insights as a quick entry point into website performance. It does not explain everything, but it shows Core Web Vitals, lab data, and specific recommendations that can affect speed and user experience. It makes the most sense when results are not treated as a score chase, but as input for real improvement.
Screaming Frog SEO Spider
Screaming Frog SEO Spider is a practical crawler for technical SEO checks. It helps crawl pages similarly to a search engine and find issues in URLs, titles, meta descriptions, redirects, canonicals, status codes, and internal links. Its biggest value appears during audits, migrations, or checks of larger websites.
SEMrush
SEMrush is a broad marketing tool for SEO, PPC, competitors, content, and brand visibility. It makes sense when several online marketing perspectives need to be connected in one interface. Its real value is not the amount of metrics, but the ability to turn them into concrete priorities.
