Chrome extensions are kinda like little magic buttons for SEOs. You click—boom!—and suddenly you’ve got data, rankings, keywords, and even a competitor’s dirty secrets (okay, maybe just their meta titles). If you’re using Plerdy, you already know how it helps track user behavior and fix conversion holes—but mix that with the right extensions, and you’re flying. No more switching between 10 tabs or begging your dev to check redirects. Whether you’re spying on backlinks with MozBar, digging keyword gold with Surfer, or running quick audits with SEOquake, these tools make SEO faster, smoother, and honestly… way less painful.
Here’s what they help with:
- Find juicy keywords in seconds
- Catch broken links (before Google does)
- Spy on your competitors without getting caught
- Check rankings from any country—even Mars (almost)
You’ll wonder how you ever did SEO without ‘em.
What Are SEO Chrome Extensions and Why Use Them?

That’s where Chrome extensions save the day. You install one tiny tool, and boom — you get data, answers, fixes, all in one browser click.
So what are SEO Chrome extensions? Think of them as little power-ups inside your browser.

No opening Ahrefs in three different tabs. Just… simple and fast.

I’m talking SEO audit, meta tags, headings, internal links, broken stuff — all from one lightweight Chrome extension. No need to open 10 tabs or jump between tools. It just works. And fast.
When I first tested this extension on my site, I was shocked. One blog post showed 3 missing ALT tags, H1 was duplicated, and keywords were all over the place. After fixing with help from the Plerdy Chrome extension, impressions jumped 66%, and 395 new keywords showed up in GSC. That’s what I call clean SEO wins.

When I used Redirect Path extension on one old client site, it found a 301 > 302 > 301 mess. The homepage was doing a triple backflip before loading. Google? Not impressed. Fixed it — boom, 17% crawl budget saved that month. It’s those small things that break your rankings quietly.
You’ll get:
