The best Chrome extensions for marketing and social media

Analyzing competitors, checking a page's SEO, grabbing a color or scheduling a post without leaving the browser. These extensions help.

Marketing work happens almost entirely in the browser: competitor websites, search engines, social networks and design tools. A good set of extensions saves you many tab switches a day.

We've picked eight, using Chrome Web Store data, each for a different task. We're the NexoPad team, which is on the list.

The 8 extensions, one by one

SEOquake

From Semrush. Checks the SEO of any page for free: titles, links, keywords and more, without leaving the browser.

Keywords Everywhere

Shows keyword ideas alongside your searches. The free part gives widgets and page analysis; search volume and cost per click require paid credits.

Similarweb

Wappalyzer

Discovers what a website is built with: CMS, analytics tools, online store and more.

ColorZilla

An eyedropper to copy the exact color of any element on a page. It works, although it's rarely updated.

Loom

Records your screen and camera to explain a campaign, present results or give design feedback.

Buffer

Schedules social media posts from any page. You need a Buffer account.

NexoPad

Saves your post copy, hashtags and comment replies with shortcuts, ready on any website. With AI to rewrite.

NexoPad: your marketing copy, ready on any website

Marketing involves lots of repeated text: the structure of a post, each campaign's hashtags, replies to comments or messages. With NexoPad you save them with shortcuts and variables. For example, with /post it asks for the news, the benefit and the hashtag, and writes the post in your scheduling tool.

With NexoPad's AI you can also select a text and shorten it, make it friendlier or translate it for your international channels.

Fill in the news, benefit and hashtag.
The post, ready to schedule.

How to choose your marketing extensions

  • Choose based on your daily work: SEO, social media, design or analytics.
  • One tool of each type is usually enough.
  • Disable the ones you only use occasionally to keep your browser light.
  • Save your campaign copy so the whole team uses the same tone. More ideas in the best productivity extensions for Chrome.
