13 Best Truly Free SEO Tools

Search Engine Optimization (SEO) techniques can help your website climb the rankings and display higher in the Search Engine Results Pages (SERPs). However, optimization can be really expensive. Premium SEO tools carry premium price tags. Fortunately, there are plenty of free SEO tools that can take your site to the next level without spending a cent.

In this guide, we’ll explore 13 of the best free SEO tools. We’ll examine each tool’s features, pros, and cons to help you decide which is right for you. Let’s get started!

What Are Free SEO Tools?

SEO is a multi-faceted approach that includes the following strategies, among others:

• Keyword research and optimization
• Meta text optimization
• Link building
• HTML sitemaps

SEO is essential to helping your site climb higher in SERP placement and attract more organic traffic. Since there are many SEO-related tasks, you might consider outsourcing the work to an agency or premium tool. This approach can save you time and effort, but can cost a lot of money.

Alternatively, free SEO tools can help you hone your strategy without straining your wallet. You’ll need to put more effort into using these tools and optimizing your site. However, if you’re on a budget and have the time to spare, these platforms’ SEO insights can be invaluable.
