26 Best Chrome Extensions & Add ons for SEO

This is a list of the best Chrome extensions and add ons for SEO purposes.

What is a Chrome Extension ?

An extension is a shortcut or additional feature of a solution that can be accessed or activated by clicking a link on your Chrome web browser.

Since the Chrome store extensions are Google approved this adds piece of mind to the security and validity of these tools.

And as Google state the extensions won’t crash your browser.

A Chrome add on doesn’t have the luxury of being inside the Chrome store.

You have to manually add it to your browser and there could be a risk of crashing your browser.

Not that the ones recommended on this list ever have crashed.

Now the list of Chrome extensions and the first one is, surprise, surprise …

Ahrefs

Ahrefs is the best keyword research, competitor and backlink analysis tool and I use it daily; because, hey, I sell keyword research services.

They have a chrome extension that displays the domain rating of a website you are one.

Do a Google search and you’ll see the local search volume, estimated clicks, keyword difficulty and global search volume.

But what’s really cool is that you can see the metrics for all the topic ranking pages underneath each search results.

The extension is a good addition to their main service.

Mozbar

The SEO world is divided into 3 fanboy camps; Ahrefs, Semrush and Moz.

The Moz Chrome extension works differently from Ahrefs; here you only see some on page metrics.

You get website metrics, when logged in, about a web page you are currently on.

And you get key website metrics laid on top of a search query you’ve made.

However, the Ahrefs extension and service versus Moz is now men against boys !

Keywords Everywhere

Keywords Everywhere is a Chrome extension I use daily.

It shows the estimated search volume, cost per click and Adwords competition next to a search query.

It also displays related keywords and people also search for keywords overlaid on the right hand side of your browser.

Whilst I use it daily and the data is nice to have, I know their data is sourced from Google’s Keyword Planner.

And the trouble with Google’s data is that it’s used for advertising not SEO purposes.

One drawback of Keywords Everywhere is that it does not help me to decide what keywords or topics to target for client’s or my own website.

I really want to like this tool but paid research tools are 100 times more beneficial to my business.

Where Keywords Everywhere becomes more useful

When you visit a web page and click their Chrome icon then their extension becomes a little more useful.

You get a keyword density and on page SEO tool that shows :

Page Title
Page Description
Word Count

Then you get to see the words and phrases contained on the page.

You can filter by 1,2,3,4 and 5 word phrases then filter those phrases by monthly search volume.

So you could use this functionality like an LSI Keyword tool if you chose to analyse a top ranking page.

Similar Web

SimilarWeb is a website research tool and their free Chrome extension will provide basic information about a website you are currently visiting.

If the icon turns to show blue and orange colours then there is information about the website.

Click the icon and you’ll get a drop down window showing:

Estimated Monthly Visits
Time on Site
Pages Per Visit
Bounce Rate
Trend of last 6 months website visits

Generally speaking that’s enough information for basic website research.

Although be aware the free extension won’t find data on many low traffic websites.

You can also drill down and see other website information including :

Traffic sources
What countries traffic comes from
Where the website traffic comes from and where it goes to

That’s very generous information for free from SimilarWeb.

I’ve not used their premium service but given the fact they don’t reveal their pricing assumes they are targeting the corporate market.

VidIQ

VidiQ is a Chrome extension Youtube analysis.

To be honest I don’t use the extension but it’s a useful reminder when I create videos.

VidIQ data is laid over your video whilst inside YouTube providing an SEO score, video optimisation checklist and video tags you’ve added or could add to.

SEM SEO Writing Assistant

If there is one feature of Semrush that would make me consider switching from Ahrefs it’s their SEO Writing Assistant.

It’s a few month since I used it on a writing project but it’s a useful add on.

SEO Writing Assistant isn’t a Chrome extension, it’s a Google Docs add on tool.

That means you access the tool from the Add on menu bar inside Google Docs.

Once you’ve connected the tool with Semrush you will see a right hand side bar containing the following SEO and writing metrics.

Overall page score between 0 and 10
Readability score between 0 and 100 where the target is over 65
Words per page
Target keywords to add to your page as you write and
Your on page title and meta description

The add on is brilliant for writer to ensure their page is relevant to the keywords they are targeting or to show the client the page is optimised correctly.

Google Docs

I use the Word Count and Spelling add ons to Google Docs every time I write a document, SEO proposal or article for a blog post.

SEO Text Optimizer

SEO Text Optimizer is a tool and extension to help you improve the relevance and thus ranking of your page in the search engines.

I used their free trial version and it was pretty good; ideal for the website owner or content writer who creates a lot of content.

Print Friendly

A Chrome extension and a toolbar add on that turns a web pages into a PDF document.

Many of my web pages have a call to action where I offer users a PDF of the website after the complete the opt in form.

Great for turning website visitors into prospects for future email marketing.

Shopify Out of the Sandbox Content Creator

I used this extension when I was creating a page for a Shopify blog.

The idea is to help you create better content layouts for Shopify pages and blog posts.

Such as adding in different columns and tables.

So when you’re inside a Shopify blog post and you need to add a row with 3 columns, you click the extension, select 3 columns and the layout is inserted into your post.

After that you populate the columns with your content.

I used to use Foundation Zurb as a web contentt framework, so this extension is kind of similar.

SEO Minion

SEO Minion is a new tool from the people at Keywords Everywhere.

And it’s very useful for 5 SEO tasks.

Analyse On Page SEO

Select this option to view the word count, page title, description, heading and open graph information about a page.

I’ve started to use this feature as I complete and launch a new web page.

Highlight All Links

For more SEO tips you really should have links to 3 other pages on your website and an external link to a relevant, authority site.

This feature helps you quickly check both internal and external page links.

Check Broken Links

Use this feature for broken link building and website maintenance.

Serps Preview

As it says, enter a keyword and you see a preview of your web page in Google search results.

Google Search Location Simulator

This is a great addition to the business of SEO :

Click this option
Enter a target keyword
Enter a url

Then you can preview how your page links in search engines in two different countries.

Find Email Addresses with FTL

Find that lead is a subscription service that helps you find email addresses associated with a website.

I don’t claim to know how they source the email addresses and as you can see from this screenshot the service isn’t perfect.

They can’t discover my email address and that’s easily found online.

Nevertheless, I find their service the best out of all the email finder tools.

I do prefer to use their website more than this extension because I need to find email addresses in bulk for link building campaigns.

So this Chrome extension is ideal when you need to find one off emails or build up a list of leads.

Find Email Addresses with Hunter.io

The Hunter.io Chrome extension also helps you find an email address from a website you are visiting just by clicking their Chrome icon.

I used Hunter.io in the past for finding email addresses and if it weren’t for a Find That Lead deal I’d still use them.

Hunter also has a Google Sheets extension that will add found email address directly into a Google Sheets document.

Kinda cool eh !

Link Klipper

The last time I used Link Klipper was to extract a bunch of website addresses from a website so I could find their contact details.

Say you are on a directory website with a list of potential companies you can to find out more information about.

Simply right click your mouse
Hover over the Link Klipper
Click extract all links

And a CSV containing all those links is downloaded.

Super fast and useful.

Full Page Screen Capture

I capture screenshots of web pages for a lot of SEO and website presentations.

My favourite screen capture tool is Snagit; a paid tool.

But sometimes Snagit has problems capturing a full web page.

So I use Full Page Screen Capture.

Simply click the icon
The tool capture the page in new browser tab
Choose to download a PDF or JPG
Download
Edit image in your editing software of choice

And Bob’s yer uncle !

Blue Button Web Page X Ray

Another on page SEO tool.

Notice that the extension highlights on page issues in red.

In this instance I don’t have alt tags for my images; something to rectify.

Back To Top

Check My Links

You can use Check My Links for two reasons.

You can use it to manually check websites or web pages you work don’t have have any link issues.

Or you can use it for broken link building purposes.

Click the icon when you are visiting a page and the extension will crawl the page and highlight in red links that are broken.

And you can use the tool during email outreach dialogues to find, screenshot and secure your broken link building opportunity.

SERPS Redux

Serps redux is a SEO bookmarklet that will extract the urls from a Google search result.

Say you need a list of website addresses from a search result, just click the link on your Chrome browser and a new window opens with all the html links.

If you change your browser settings to display the top 100 results, you can collect more URL’s faster.

Just copy and paste into a document or spreadsheet the URLS that have been extracted.

Shopify Bulk 301 redirect

Those business owners new to Shopify go mad creating hundreds of catalogs and tags in their e-commerce website.

They end up creating too many, low quality and duplicate collections.

So us SEO guys have to clean up their website structure and ensure only their best pages are indexed in Google.

Using 301 redirects is a good way to manage some of this house keeping and spring cleaning.

Back To Top

This little extension isn’t really an SEO extension but it’s good to know you’ve installed the Facebook pixels correctly for re-marketing to those who have visited your web page from organic search results.

My website has 2 distinct audiences and knowing I can re-market on a per page visit basis is super useful for targeted advertising.
