Whether you are an SEO fresher or working in a digital marketing agency, we all want tools that will simplify the process of SEO while also improving the results.
SEO chrome extensions not only make the SEO optimization process easier, but these extensions also help to eliminate the need for expensive tools.
But finding the best ones out of many can be an exhausting process. To help you out finding the right Chrome extensions, I’ve compiled a list of the best SEO Chrome Extensions that users trust, rank on Google, and are compatible with SEO practices.
Ubersuggest – Best for Keyword Research & Competitor Spying
Chrome Rating: 4.5/5
Ubersuggest, created by Neil Patel, is a fantastic free SEO tool that shows keywords’ monthly search volume, CPC, & Competition data.
The Ubersuggest tool also shows the top-performing keywords of your competitor’s website. With this data, you can improve your keyword strategy and see which keywords are worth targeting.
Through this data, you can find out the opportunities and the list of keywords you might be missing.
UberSuggest extension isn’t just for Google! But also provides the insightful data on sites like YouTube, Amazon & more.
Aside from keyword insights, Ubersuggest also provides data on your competitors’ backlinks, and you can view metrics like Domain Authority, the number of referring domains, and monthly organic traffic.
Despite being a free Chrome extension, you are limited to 40 searches per day. It can help a beginner, but if you are a professional or a team of digital marketers and need detailed information, you need to buy the subscription.
Pros:
- Shows top-ranking keywords and estimated traffic for any competitor’s site — on the free plan.
- Works across Google, YouTube, and Amazon in one extension.
- New AI content idea generator available directly from keyword suggestions.
- Backlink overview (DA, referring domains) included without logging in.
- Cleaner interface than most — beginner-friendly without dumbing down the data.
- The extension auto-disables after 3 days of inactivity to stop slowing your browser.
Cons:
- Free plan still caps you at 40 searches per day — which sounds fine until a big research session.
- Paid plans jumped in price; Individual plan is now $29/month (was cheaper in 2024).
- Data accuracy still lags behind Ahrefs and SEMrush for newer or niche domains.
- Occasional slow load on older devices when the sidebar pulls up competitor data.
- Chrome-only — no Firefox or Safari version as of early 2026.
Best Use Case: Freelancers, bloggers, and small business owners who want quick competitor insights and keyword validation without committing to a $100+/month platform. The free plan covers most day-to-day research needs.
Mozbar – Best for Authority Checks & Link Building Qualification
Chrome Rating: 4.0/5
Mozbar created a metric named Domain Authority (DA). Domain authority is used to define how your website ranks in search results. The higher the domain authority of your website, the higher the chances of ranking in search engine result pages.
The Mozbar tool is a free extension that provides metrics like domain authority, page authority, and spam score of any website. You can also view on-page elements like the markups, HTTP status, title tag, meta, heading tags, and image alt texts.
The premium version provides you with more detailed information, including link metrics, top-ranking keywords, in-depth SERP analysis, and page optimization. Moz Pro gives a free trial for 30 days, and a monthly subscription starts at $49.
Pros:
- DA and PA metrics are the most widely recognised authority scores in the industry.
- Spam score catches bad link prospects before you waste outreach effort.

- Custom search lets you simulate results from specific locations or search engines.
- Link highlighter differentiates internal, external, followed, and nofollow links visually.
Cons:
- Moz Pro has jumped to $167/month — hard to justify if you only want the extension features.
- Free version is noticeably bare compared to what premium unlocks.
- DA scores can be misleading for brand-new sites and very niche verticals.
- Some users report slow load times when browsing heavily linked pages.
- Interface looks dated next to newer extensions — function over form.
