46 of The Best FREE SEO Tools To Improve Your Online Marketing
Updated January 2019
Do you want to drive more visitors to your website?
Of course you do.
An important part of getting people to your website includes your ranking in organic search results, which is where search engine optimization (SEO) comes in.
Put simply, SEO is about making sure that your website appears prominently on a search engine results page (SERP) when a person types in keywords related to your business.
As a business owner, it’s vital that you understand the importance SEO plays in your online presence, and how best to optimize your content for online success. But with SEO an ever-changing field (as Google’s frequently shifting guidelines can attest to), it can seem daunting if you don’t know where to start.
You could always outsource the work to an SEO agency but this option can be expensive and out of reach for the average small business owner.
The good news is that there are search engine optimization tools available to help you do your own SEO — and many of them are free.
I’ve put together this list of the best free SEO tools out there right now to help you instantly improve your online marketing.
Ahrefs is a super tool to help you focus your link building efforts. It allows you to perform competitive backlinks analysis and identify quality links your competition is getting. Use it to see who links to your website because sometimes spam sites link to you and the danger with this is that Google will consider you spammy then too and push you down in rankings.
