Updated: Feb 11, 2021

This is an inventory of the best free SEO tools that exist today!


Hi Queens, are you having trouble ranking on the first page of google organically?



If you want to boost your online presence and get in-front of more eyes online, you have to make sure your SEO game is on point! How? With dope content as well as SEO.


SEO is an acronym that stands for search engine optimisation, which is the process of optimising your website to get organic, or unpaid, traffic from the search engine results page. In order to do this, search engines will scan, or crawl, different websites to better understand what the site is about.


All of these tools below work GREAT in 2021!


Let’s get started…


1. WooRank’s SEO Checker


Get an inventory of SEO improvements in seconds.


This is a really handy Chrome extension. First, you get an overall SEO score. Then, the tool shows you EXACTLY the way to improve your site’s on-page and off-page SEO.

Best Features:


If you manage your own website, it's easy to accidentally create HTTP errors that you don't see on your own. Site crawling exposes any major flaws in the way you set up your site. This way you can do everything the way you want.


Index errors are not easy if you don't know what to look for. WooRank makes it easy to spot any indexing errors during your regular SEO checkup. By fixing the deficiencies as soon as they appear, you can avoid the long-term problems they cause.


Nowadays, search results are based on geolocation. For more precise local search data you can localise your keyword tracking by country, city, county, or state/province.


It is easy for you to take advantage of your ranking. WooRank's site crawl explains where you can improve your page for the best results. This is a great way to ensure you are following best practices.

2. SEMRush


SEMRush could be my all-time favourite SEO tool.


Yup, it’s also got a paid plan with many great features! Whether you accompany free or paid, SEMRush works an equivalent way. It finds the precise keywords that your competitor’s rank for.


Best Features:

Content optimisation based on your top 10 competitors in Google rankings. Check your content for online SEO friendliness and originality - adjust the readability and tone of your copy's voice.


Keyword-rich content ensures your webpages appear in Google's top results. In addition to updating your web text with valuable keywords, variations of those keywords also help ensure successful keyword optimisation. SEMrush serves as a powerful generator to extend the keyword pool for your website.


You should never rely on top keywords. In fact, the most popular keywords have the largest search volume; However, every day, thousands of your potential customers use short-section search terms for their queries. These types of keywords are called long-tail keywords, which represent 70% of all search traffic.

Good content meets the needs of your audience and is increasingly found online. To ensure that your copy meets both requirements before publication, you need to consider different parameters. All you need to do is to use SEO Writing Assistant and get a list of SEO recommendations that can be used to type in your target keywords for a copy.
