Have you ever stumbled upon a fascinating blog and wondered what platform powers it? Identifying whether a site is built on Google’s free Blogger (formerly Blogspot) service, WordPress, or another CMS can be useful for SEO analysis, design inspiration, or simple curiosity. While the distinct .blogspot.com URL is an immediate clue, many bloggers use custom domains, making the task trickier. This guide walks you through multiple methods to definitively identify a Blogger-hosted site.

⚡ Method 1: The Quick URL Check
The most straightforward way to identify a Blogger site is by examining its web address:
- Any site ending in
.blogspot.comis hosted on Blogger. - Examples:
https://light-on-the-screen.blogspot.comhttps://spreadsheetssimplified.blogspot.com
Bottom line: Seeing .blogspot.com immediately confirms the blog is hosted on Google’s platform.
⚡ Method 2: The Custom Domain Challenge
Many bloggers purchase a custom domain (e.g., www.blogs.erickouassi.com) to appear more professional and improve SEO. This masks the underlying platform, so you cannot rely solely on the URL. In these cases, you need to dig deeper using technical methods.
⚡ Method 3: Inspecting the Page Source Code
The source code of a webpage often contains “fingerprints” of the CMS used. Here’s how to check:
- Open the website in your browser.
- Right-click and select “View Page Source” or “Inspect”.
- Use the Find function (Ctrl+F or Cmd+F).
- Search for keywords like
bloggerorblogspot.
If these terms appear in meta tags, scripts, or comments, it’s a strong indicator the site is powered by Blogger.
📚 Example Use Case
Imagine you’re analyzing a competitor’s blog with a custom domain (https://www.peggyktc.com). At first glance, it looks like WordPress. But when you inspect the source code, you find references to blogger in the HTML. This confirms it’s actually a Blogger site with a custom domain. Knowing this helps you benchmark your SEO strategy against theirs more accurately.
⚠️ Disclaimer
This guide is for informational purposes only. While these methods are reliable, platforms evolve and may change their identifiers over time. Always cross-check multiple indicators before drawing conclusions.
🧠 Final Thoughts
Identifying whether a blog is hosted on Blogger can be as simple as spotting .blogspot.com or as technical as inspecting source code. With these methods, you’ll be able to uncover the platform behind any blog, whether for SEO analysis, design inspiration, or pure curiosity.
