SEOs can also check the status of various technical elements like schema and redirect chains. Which are essential to your page’s technical SEO optimization. 

The extension includes several distinct tabs dedicated to different helpful data points. Like: 

Overview: This includes details like the title tag, meta description, URL, meta robots, and Google core web vitals. You can also check the website’s sitemap and web vitals performance. Plus, it lets you export the page copy in a .txt file.

Headings: This includes information for a page’s headings (e.g., <h>) tags. These are important for structure and help crawlers read your page. 

Status: This shows status codes for web pages, such as 200 (OK), 404 (not found), or 502 (bad gateway). If a website’s status code shows an error, you know something is wrong with the page, server, or something else.

Links: This includes a breakdown of internal and external links. You can also highlight nofollow links and export all the links to plan your linking structure. 

Images: This breaks down images on a page into two groups, those with alt text and those without. This makes it easy for SEOs to include alt text to make images more accessible for users and search engines alike.

You can also preview the open graph (a protocol that creates rich media displays for webpages) for this page on social media platforms and URLs. 

It is important to make sure your pages look good when readers share them on social media channels. 

5. META SEO Inspector

META SEO Inspector provides comprehensive insights into your page’s metadata in a single click. 

Meta tags are a critical part of your page’s HTML code. They help search engines understand your pages and influence how these pages appear in search results. 

With an SEO Chrome extension like META SEO Inspector, you can get a report about metadata for your website pages. 

For example, the tool mentions discrepancies in your page structure, such as adding an H2 instead of an H3. 

The tool pinpoints issues for various page elements in the schema, like anchor text, images, iframes, and more. 

Here is an example of images with issues related to width and height attributes. 

Overall, this extension flags (and advises you on how to fix) some of the most common issues with metadata, including:

Although primarily for developers, META SEO Inspector can be a useful tool for SEOs, site owners, or anyone interested in learning more about their site’s metadata. 

Plus, you can use this tool in 10 languages, including Dutch, Italian, Polish, Spanish, and more.

6. Hreflang Tag Checker

Hreflang Tag Checker helps you verify that your pages use hreflang tags appropriately.

Hreflang refers to HTML attributes that indicate a webpage’s language and targeted region. 

These tags help search engines understand the language and regional targeting of a webpage. And they direct users to the correct version of a site based on their language and location. This means that visitors are more likely to see content tailored to their preferences. Helping you deliver a great user experience.

Hreflang Tag Checker helps you identify the languages in which a page is available. For example, in this image below, the tool shows that a Semrush page is available in three languages: English, Spanish, and Portuguese. 

The tool crawls a page to identify its language attributes and hreflang architecture. This makes it significantly easier to audit your site’s suitability for success in all your target languages.

7. SEO META in 1 Click

SEO META in 1 CLICK shows all the meta tags and data you need to manage to optimize your website’s search performance. 

The tool includes five tabs:

Summary: This provides a page overview with the header tag, meta description, keywords, canonical tags, and other details. A red highlight means your title or description is too long. 

Headers: This shares a breakdown of the headers in a page. You can use this structure to guide your research and outline process when building new pages or writing articles. 

Images: This includes a list of all the images with or without the alt text and title. Export this list to add the alt text and title for specific images. 

Links: This breaks down the internal and external links with the anchor text. It also flags links without a title.

Social: This shows the open graph for social platforms. You can check whether all the open graph elements are available for a page or not.

Finally, the Tools tab links out various third-party tools. You can check out these tools to analyze your page performance in terms of:

• Responsiveness and mobile-friendliness
• Page loading speed
• CSS elements

This matters because pages with bad mobile-friendliness, slow loading speed, or misfiring CSS elements could deliver a poor user experience. 

These technical SEO issues can negatively impact your search performance. 

8. View Rendered Source

View Rendered Source lets you quickly compare a page’s source code to its rendered version in a browser. In other words, the tool allows developers to quickly compare the differences between a page’s raw HTML version and how the browser interprets this page. 

This comparison helps SEOs debug issues related to the page design and code. 

You can also improve specific elements that affect the page’s responsiveness or how search engines interpret your page by analyzing the source code and identifying errors.

Since differences between the page’s source and rendered versions are color-coded, you can easily find and fix issues. The red highlight indicates the “before” version (the original code) while the green color highlights the “after” version (the rendered version). 

For example, this screenshot shows the before and after comparison in the source code of a page.

9. Detailed SEO

Detailed SEO gives you insights about any webpage. This includes the page’s meta title, description, URL, and robots tag.

This snapshot will also tell you about the word count, number of headings, and images on the respective page.

This is great for creating SEO-friendly articles. You can use this extension to quickly scan top-ranking articles and structure your content better. 

Plus, Detailed SEO gives you a list of all the links on a page. These links are categorized as internal and external with the option to export the entire list. 

Use this list to regularly audit your link structure and build more internal links for better SEO performance.

You can also access the schema markup for any page to get more contextual details like published and modified dates, meta descriptions, links, etc. 

It gives you a glimpse of how search engine crawlers see and understand this webpage. 

You can also go to the advanced tab where you’ll find the option to access Semrush’s Domain Overview report. This report will tell you the website’s authority score, organic search traffic, backlinks, and organic keywords, among other insights. 

And when you check “Enable PAA Extracting” in the Advanced Settings tab, the tool alters your search results pages to show the “People also ask” questions up top. 

The “People also ask” segment typically comes right below the first search result. 

10. SEO Search Simulator by Nightwatch

SEO Search Simulator helps SEOs see the search results for any keyword across different geographical locations and languages. 

For example, when you enable this Chrome extension and set the location to Belgium, these are the search results you’ll see the keyword “product discovery.” 

You can also add specific URLs in the “Find URL” search bar. This will allow the tool to find the rankings for each page in the search results for a specific location.

You can see the rankings for your URLs in any part of the world. It’s helpful for international SEO since you can see results in the local language and tailor content for target locations. 

For example, you’ll find the top-ranking posts for a specific location and identify which brands are creating content in this language.

11. Lighthouse

12. NoFollow

NoFollow is one of the most lightweight SEO Chrome extensions that can identify link types and no index tags.

The tool differentiates types of links (follow, nofollow, sponsored, and UGC) with a color code. 

In this image, all the follow links are highlighted in a green dotted box. Nofollow links are highlighted in red.

You can also disable the Chrome extension for specific websites so it doesn’t analyze any data. Or temporarily disable the extension when you want a cleaning browsing experience.

13. Check My Links

Check My Links helps SEOs identify broken links on any website and maintain its linking structure. 

This extension crawls a page to find any broken links. 

For example, in this screenshot, the tool highlights all the valid links in green. The report snippet also tells you that this page includes one invalid link highlighted in red. 

By identifying invalid links, the tool enables regular website maintenance to clean up your internal linking structure and deliver a seamless user experience. 

Another key use case for this SEO Chrome extension is dead link building. 

This means you can open any website where you’d like to secure a backlink. Then, open different pages and use this extension to spot invalid links. 

When you find broken links on a target website, you can approach the site owner to replace these dead links with your own content. 

You can maximize your website’s SEO health by using this Chrome extension together with Semrush. Run a Semrush Site Audit and create a list of pages with errors flagging broken links. 

Then, evaluate these pages using the Check My Links extension to find 3XX and 4XX links in your site structure. 

HTTP Headers helps developers view HTTP headers in browser requests and fix any errors. 

When you click on the Chrome extension, this tool gives you an overview of the URL’s HTTP requests and responses.

You can diagnose issues like missing headers, incorrect content types, or inaccurate status codes.

You’ll get a time-stamped report for all URLs with their exact status and error codes. You can also see the raw and formatted version of each request in the right panel. 

This Chrome extension helps you optimize performance and load times. 

You can verify if caching headers like Cache-Control and ETag (headers used to manage browser cache) are correctly set. And test custom headers to ensure they are correctly formatted and transmitted. 

By verifying HTTP headers, you can optimize page load speed, user experience, and overall site performance. Correct custom headers provide additional information to search engines about a page—like content types and language preferences—and facilitate efficient crawling. 

15. Web Developer

Web Developer adds a toolbar to your browser for quick access to features like clearing cache, disabling cookies, and displaying hidden elements. 

As an SEO, these features will allow you to efficiently test and optimize your website’s performance. Plus, you can make necessary changes like clearing cache or adjusting cookies to improve the user experience.

It can also secure your browsing experience by disabling JavaScript. This move will prevent the risk of hackers running malicious code on your system. 

Another use case for Web Developer’s toolbar is viewing a site in different layouts or screen sizes. This is good for testing whether your website design is mobile-friendly and responsive enough for all types of screens.

Once you add a keyword, Glimpse curates a list of questions, terms, and brands from the People Also Search segment. These keywords have an overlap with your primary search term. 

This overlap means people searching for the primary keyword are also looking for these other terms. 

You can use this feature to build keyword lists and collect a list of questions to answer and address through your content.

Additionally, Glimpse lets you set alerts for a particular keyword. Once you’ve created an alert for a keyword, the tool monitors the trends and notifies you if its search volume increases drastically.
