    SEO-related Chrome extensions can help you work faster and smarter. 

    I’ve tested a few dozen popular free Chrome extensions and included 14 of the most useful ones in this article.

    This extension allows you to inspect the meta information on webpages, find issues, and get advice to fix them. It covers meta tags, canonicals, Open Graph tags, structured data, hreflang, subheaders, and more.

    It also provides advanced data about the internal and external scripts used on the page.

    Unlike many other extensions, Hreflang Tag Checker does not simply list a page’s hreflang data. It actually crawls the links in hreflang tags to check if they link back to the page you’re visiting.

    TextOptimizer describes itself as a writing assistant tool. It analyzes search results for relevant terms and extracts “intent tables” to suggest other words that you can use in your copy “to better match search engines’ expectations.”

    There are more than enough premium content optimization tools on the market, but TextOptimizer does a good job as a free tool.

    This extension gives away a good amount of data for a free tool: Keyword search volumes, keyword ideas, and domain-level traffic estimations are provided straight on Google’s SERPs.

    The SEO Minion extension is one of the multi-tools for SEO. It allows you to check on-page SEO data, highlight outgoing links, and check pages for broken links.

    Arguably, its best feature is the multilevel “People Also Ask” query export from the SERP. This will provide you with related long-tail queries that you can consider when creating a new piece of content.

    The Glimpse Chrome extension turns Google Trends into a keyword research tool. It enriches Google Trends data with keyword search volumes, long-tail keyword suggestions, and a topic map.

    However, you should note the free version allows only 10 searches per month. You’ll also need a paid subscription for extensive keyword research.

    This is a must-have tool for those who work with JavaScript-powered websites.

    It compares the raw page code and its rendered version. And SEOs can check, for example, if JavaScript overwrites titles, descriptions, or canonical tags.

    With Similarweb for Chrome, you can check estimated traffic, traffic sources, visitor geography, and other key statistics for any website.

    Final thoughts

    There are quite a few Chrome extensions that bring the features of online SEO tools and services right into your browser. I hope this post helps you find an extension or two that will have a significant impact on your productivity and will save you lots of time.

    Just keep in mind that using too many browser extensions may slow down your computer—so choose them wisely.

    If you use a lot of extensions, you can always create multiple user profiles for different tasks

    Then you can install different extensions on each profile and switch between them as needed.

    You can also use the One Click Extensions Manager to keep your extensions neat and orderly.
