Looking for the best SEO extensions for Chrome? You’ve come to the right place.
SEO extensions for Chrome can help you analyze keywords, optimize your content, build links, and collect all the data you need to rank higher on Google.
The best part is that they let you do all this while browsing the web in Chrome, without having to open multiple apps.
In this article, we will show you the best SEO extensions for Chrome and how they can help you with your search engine optimization strategies.
1. Detailed
The Detailed SEO plugin was created by renowned SEO blogger Glen Allsopp. It provides detailed information about a page’s SEO at the click of a button. It lets you see key elements on the page, such as title and meta tags, the hierarchical structure of headings, and whether images lack alternative text (alt text).
It is one of the simplest extensions among the all-in-one options mentioned in this article and is compatible with any SEO software. It also has shortcuts to external tools such as Ahrefs, Moz, SEMrush or the Wayback Machine for more information.
2. Mozbar
Mozbar is an all-in-one extension from Moz and one of the most popular extensions for SEO on Chrome. When browsing a web page, you can quickly see essential elements on the page such as title and meta description tags, as well as Schema markup. Additionally, it provides link metrics and HTTP statuses.
Its standout feature is that it shows the Page Authority and Domain Authority metrics of any web page or result on Google. The only condition is that you need to register for a free Moz community account and log in.
While Mozbar doesn’t offer keyword difficulty metrics on free accounts, it does allow you to compare the page and domain authority of the top results on Google to your own website to assess the viability of ranking for a keyword.
3. Ahrefs SEO Toolbar
Ahrefs SEO Toolbar is an extension from one of the most trusted names in SEO. It allows you to check on-page elements, indexability, and image optimization for free. It also suggests related keywords within Google results, among other features.
Paid Ahrefs users can quickly access key metrics like Domain Rating (DR) and URL Rating (UR). Additionally, they can see which keywords a page ranks for and what backlinks it’s attracting, which is extremely useful.
4. Keywords Everywhere
Keywords Everywhere is one of the most popular extensions on this list, with over a million installations.
Shows search volumes for keywords across Google, YouTube, Google Search Console, Keyword Planner, and more.
It used to be free, which made it very popular, but now it comes at a low cost: for $72 a year, you get 400,000 credits that can be used to view search volumes, backlinks, and other metrics. Plus, with a paid account, you unlock SEO Minion, a complementary extension with similar features to other all-in-one SEO tools.
5. Keyword Surfer
Keyword Surfer is a simpler version of Keywords Everywhere, but completely free.
The only drawback is that it only works on Google. After you perform a search, it displays the search volume for each keyword to the right of the results. It also offers related keyword ideas along with their search volumes in a sidebar.
Its big advantage is that it is free and supports multiple countries, making it easy to research keywords in different markets.
6. TubeBuddy
TubeBuddy is another very popular extension with over a million installations. It is designed to improve SEO on YouTube.
When you enter a keyword into YouTube, it gives you data on its search volume, competition, and tells you whether it’s worth optimizing your channel for that keyword.
Its main features are free, and it stands out for showing accurate statistics such as the exact search volume for a keyword and how well-optimized the videos are in the results for that term.
7. Grammarly
Grammarly is easily the most popular extension on the list, with over 10 million installs.
As its name suggests, it helps you improve grammar, correct errors and perform style revisions, but it also optimizes the clarity and readability of your texts.
Despite the rise of new AI writing tools, Grammarly remains a top choice.
8. Sider
Sider is a versatile extension that combines artificial intelligence with several useful tools to improve writing and productivity.
It offers features like AI Essay Writer, Grammar Checker, and Writing Improver. It also includes advanced tools like AI Translator, YouTube Video Summarizer, PDF Translator, OCR, and Image Background Remover.
Whether you need to refine an email, summarize a video, or edit an essay, Sider has you covered.
9. Notion Web Clipper
Notion Web Clipper lets you capture and save web content directly into your Notion workspace.
You can save entire pages, specific sections, or links for future reference, making it easy to organize information for personal or professional projects.
10. Google Search Console Enhanced Analytics
Google Search Console Enhanced Analytics saves time within Search Console by allowing you to:
- Quickly change comparison dates beyond Google’s defaults.
- Display percentage changes between time periods.
- Generate search volumes.
- Export data with newly generated metrics.
Although the extension is free, to access search volumes you need a subscription to the DataForSEO API, which costs $0.05 per 1,000 keywords processed.
11. Web Developer
Web Developer is another popular extension with over a million installations. It adds a number of tools for web developers and technical SEOs.
It allows you to examine the structure of a page on different devices, analyze headers, and highlight images without alt text. It also makes it easy to disable JavaScript to evaluate how a page performs without it.
12. Mangools
Mangools is a very beginner-friendly SEO toolkit, and their Chrome SEO extension is excellent – in fact, it’s one of my favorite parts of the tool.
You can use it to get key SEO metrics for any website, such as Domain Authority, Page Authority, and Citation Flow.
Additionally, it will show you the keywords the page you are visiting is ranking for (along with its ranking position), the backlinks pointing to it, and all relevant on-page SEO data.
Chrome extensions can speed up key SEO tasks like keyword research and competitor analysis, while also optimizing your site’s performance.
However, to increase web traffic, you need more than just tools.
An effective SEO strategy combines technical optimization, engaging content, and a deep understanding of your audience.
