Why SEO is Important

Most readers won't need this primer, but it never hurts to reiterate how important SEO is for your business' bottom line.

How many people are using a search engine to research before buying?

  • 68% of B2B customers use search to research online for a solution to their need.
  • 85% of ecommerce consumers research before making a purchase.

Okay, those are big numbers. But does it actually matter where you rank?

Yes. Yes it does.

  • Between 75% and 90% of traffic clicks on the ranking pages on page one (depending on who you ask).
  • About 60% of searchers click on the top 3 spots. Roughly a third of all searchers click on the top spot.

The graph below shows how quickly click-rates drop as you move down the SERP. Take a look:

10 SEO Chrome Extensions for Competitor Analysis

Keeping an eye on your competitors is a crucial part of doing business, no matter what department you're in.

For search optimizers, watching your competitor's pages can inform your own SEO strategy and help to identify gaps in theirs.

These 10 SEO Chrome extensions are built to more effectively dig into the pages, websites and ranking links of your business' competitors.

Let's check them out.

SEO Search Simulator

5 Stars      |      9,045 users

Data Scraper — Easy Web Scraping

4 Stars      |      175,929 users

This is an SEO Chrome extension which some could argue leans towards the grey-hat side of the coin.

You can also export web pages into XLS, CSV, XLSX or TSV files.

AdBlock

4.5 Stars      |      10,000,000+ users

How is an ad blocker extension related to SEO, you ask?  SEO is all about ranking organically. Unless you have a good ad blocker, you can get bogged down (or even lose sight) of where your competitors are ranking organically.

It's surprising how many marketers and search optimizers are still trawling through Google without a good ad blocker.

WhatRuns

4.25 Stars      |      165,585 users

The WhatRuns Chrome extension allows you to see (as you might expect) the systems and platforms which run your competitor's websites (or perhaps just the websites you love).

A cool feature is that you can "follow" websites to receive a notification if they start using any new technology or remove an existing one.

Who are we kidding? Every marketer or search optimizer has done a bit of "competitor stalking" now and then.

Wappalyzer

4.75 Stars      |      982,426 users

The Wappalyzer is a similar extension to WhatRuns, so if you're dissatisfied with one, check out the other.

4 Stars      |      10,117 users

Another "shortcut" extension, gInfinity enables infinite scroll for Google search results.

Scroll down to the bottom of the search result and the following 20 search results are automatically added to the search result.

Realistically this SEO Chrome extension saves you 10 or 20 seconds a day. But, when added up, those seconds count.

LinkClump

4.75 Stars      |      260,042 users

LinkClump lets you open (or copy, or bookmark) multiple links.
