Within seconds, you can see your Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS), which are all crucial for Google’s ranking signals.
One of my favorite features is the Waterfall Chart. It shows exactly how each element on your page loads, so I can pinpoint what’s slowing the site down.
I’ve used it to identify unoptimized images, bulky JavaScript files, and even third-party scripts that hurt performance.
When clients ask, “Why is my site so slow on mobile?” I often run it through GTmetrix.
The tool gives clear scores and actionable suggestions like enabling compression, deferring unused CSS, and using a content delivery network (CDN).
You can also test your site from various locations and browsers.
If you’re looking to improve mobile SEO and user experience, GTmetrix is a tool you must explore.

As an SEO professional and content strategist, Google Trends has become one of my favourite tools to discover real-time search insights, seasonal trends, and audience interest patterns, all directly from Google.

Google Trends isn’t just a research tool, it’s a strategic content compass. Here’s how I use it regularly:

10. SERP Simulator
If you’ve ever wondered, “How will my page look on Google before I hit publish?”
or
“ Is my page title too long to display correctly on mobile devices?
a SERP Simulator is your best friend.
As an SEO strategist, one of my favorite pre-publishing tools is a SERP Simulator. It lets me preview exactly how my title tags and meta descriptions will appear on Google, across both desktop and mobile devices, before I go live.
Features That Make It Invaluable for SEO
- Live SERP Preview: You get a real-time preview of how your page will show up in Google search results, helping you avoid cut-off text.

- Rich Snippets Support: Some simulators allow you to preview structured data, like star ratings, FAQ schema, and breadcrumbs.
- Keyword Highlighting: See how your target keyword stands out visually in the title and description.
How I Use It in My SEO Workflow
Let me give you a real-world scenario. When I was optimizing a landing page for the keyword “best CRM software for startups”, my original meta title looked like this:
“Explore the Best CRM Tools for Startup Success | Free Trial Available”
But the SERP Simulator showed me that on mobile, the last part (“Free Trial Available”) was getting cut off. I reworked it to:
“Best CRM Software for Startups – Try It Free Today”
This version was shorter, keyword-rich, and perfectly visible across devices. The result? A noticeable bump in click-through rate (CTR) within two weeks.
11. Google Search Console

This level of detail empowers me to make precise improvements, which has resulted in faster site speeds, lower bounce rates, and better overall engagement.
For any business looking to enhance its local search performance, improving site speed is critical.
