1. Ubersuggest

Ubersuggest isn’t just a great SEO extension—it’s one of the most comprehensive free tools for keyword and traffic analysis.

Why? Because Ubersuggest’s Chrome extension lets you view keyword data right from Google search results.

If you expand the ‘view all’ options from Ubersuggest, you can see:

• Monthly searches
• CPC
• Age range
• Related keywords and the percentage of people who clicked on SEO results

It also shows related keywords and their information without leaving the SERPs. You can export the data to CSV or click on any information headings under “People also search for…” Click any keyword to open the Ubersuggest dashboard for deeper analysis and content planning

Aside from at-a-glance keyword insights, you can also see domain overviews and perform traffic analysis to develop a comprehensive SEO strategy.

2. MozBar

Domain authority (DA) is a metric created by Moz that defines how likely your site is to rank in search engine results. Generally speaking, the higher your domain authority, the higher your rankings.

Moz created an SEO plugin for Chrome called MozBar that gives you instant metrics for domain and page authority for any page on the web. However, there’s a lot more to it than that.

You can also:

• Customize searches by engine, country, region, etc.
• Compare links and find opportunities for backlinks.
• Discover and highlight keywords to understand different keywords by type, such as follow, no-follow, external, and internal.
• View on-page elements like markups and HTTP status for quick SEO assessments.

New features include:

• Measuring brand authority (A Moz metric measuring brand strength and influence) for Premium users.
• A popup extension that complements the MozBar.
• Updated page analysis for hreflang tags, robots.txt, and sitemaps.
• Discover and copy schema markup from web pages to simplify auditing.
• Access and compare link metrics on pages.
• Export SERP analysis in a CSV file.
• Access page optimization info to understand the factors influencing the page’s ranking abilities.

Use MozBar to analyze competitor websites, identify backlink opportunities, and track keyword difficulty in real time.

Additionally, as you go through your rival’s site, you can easily spot their most authoritative pages that need analyzing.

If you upgrade to a Moz Pro Subscription, you can also access keyword difficulty, page optimization, and in-depth SERP analysis. Moz Pro offers a free 30-day trial, and monthly subscriptions start at $49.

3. SimilarWeb

Want to see how top websites drive traffic? SimilarWeb reveals competitor strategies in real time.

With SimilarWeb, you can get website traffic and engagement metrics, global ranking data to evaluate site performance, and in-depth statistics for every website. 

Its numerous features mean it’s considered a top SEO plugin for Chrome for competitive research. This includes:

• Traffic sources and ranking.
• Keyword ranking.
• The top-performing keywords for any website.
• Top countries driving traffic and percentage of visitors for individual countries
• Visits over time.

Finally, you get an overview of your traffic sources, like search, email, social media marketing, and direct ads. The more you know about your traffic sources, the better you can refine your content/marketing strategy.

4. Ayima Redirect Path

Broken links and misconfigured redirects can hurt your SEO—Ayima Redirect Path helps you spot and fix them instantly.

Ayima’s Redirect Path works on your computer to identify HTTP status codes. You can quickly see if a redirect is broken or working correctly and it helps to troubleshoot and optimize site redirects.It also highlights status codes like, 301, 302, 404 and 500 HTTPs.

In addition, it details Meta and Javascript redirects, bringing these issues to your attention and allowing you to fix them when errors occur.

The plugin also details HTTP headers, such as caching headers and server IP addresses, at the click of a button.

5. Meta SEO Inspector

Meta tags can make or break your SEO—by using the Meta SEO Inspector SEO plugin for Chrome, you can quickly determine whether your meta tags have been set up correctly with one click.

As you can see from the screenshot above, this tool detects tagging errors that could otherwise go unnoticed.

According to the Chrome Web Store page, the Meta SEO Inspector extension is for web developers who want to validate their website’s HTML to ensure it complies with Google’s Webmaster Guidelines.

You can examine all meta tags and data with a single click to ensure proper implementation and identify potential issues.  

There’s a whole suite of additional features, too. With the reports you can:

• Study your competitor’s metadata.
• Copy the meta tag values into a clipboard.
• Export/print your reports.

As a bonus, the team behind the Meta SEO Inspector tool keeps it regularly updated, and it’s translated into multiple languages.

6. PageSpeed Insights

My past research shows that e-commerce loading times often aren’t great, but the PageSpeed Insights extension is a top SEO plugin for Chrome.

With the Pagespeed Insights extension, you can quickly identify what you need to improve on any website page to increase page speed. It gives you real-time Google Pagespeed Insights scores for both desktop and mobile, including:

• Speed Index
