A wise person once stated, “We’re all in the same space—the space for improvement.” This rings especially true for websites. While we should always be exploring ways to enhance their effectiveness, it’s not always simple to identify problem areas or growth opportunities on our own.

This is where website grader tools prove invaluable, as they conduct evaluations for you and generate actionable reports based on their findings. In this article, we’ll examine 11 free website graders that assess content, search engine optimization, accessibility, and other website aspects, including marketing.
SEO Website Graders
SEO is a multifaceted field. Reaching Google’s first page and maintaining that position demands considerable effort. For those who aren’t SEO experts, accurately gauging your performance can be challenging. And even for the seasoned professionals, having tools to validate your efforts and ensure you’ve covered all bases is beneficial.
1. Google PageSpeed Insights
Page speed plays a crucial role in technical SEO. Visitors are impatient; if your site is slow, they’ll simply leave and seek alternatives. This is where Google PageSpeed Insights comes into play. It’s a page speed grader that evaluates your mobile and desktop sites, assigning scores based on the quantity and severity of performance issues, including your Core Web Vitals—metrics introduced in spring 2021 with the page experience update.
The report highlights areas for Core Web Vitals improvement and suggests opportunities for optimization, such as:
- Compressing text
- Optimizing image sizes
- Minifying CSS
- Improving JavaScript execution time
- Ensuring text visibility during Webfont loading
Some page speed optimization techniques are beginner-friendly. However, for others, seeking expert assistance might yield optimal results.
2. LocaliQ Free Website Grader
While important, Core Web Vitals represent only a fraction of the numerous Google ranking factors, both technical and content-related, that demand optimization for increased traffic. Although comprehensive SEO and keyword research tools like Ahrefs and Semrush can aid in optimizing your SEO content, their reports are extensive and require more than just basic SEO knowledge to decipher. LocaliQ’s Free Website Grader conducts an immediate audit of your website, evaluating a combination of technical and content SEO elements, including but not limited to:
- Meta tags
- Word count

5. Hemingway Editor
Hemingway Editor isn’t your typical website or marketing grader where you input a URL for an audit report. Designed for optimizing individual pages, it provides a readability rating based on your content’s reading grade level. More specifically, this rating considers:
- Adverb usage, often replaceable with more impactful alternatives.
- Opportunities to replace passive voice with active voice.
- The presence of complex phrases that can be simplified.
- The number of hard-to-read and very hard-to-read sentences, aiding in clarity optimization.

The report explains how to address issues and their locations on your site. Admittedly, some technical language, particularly regarding CSS, might be challenging for non-experts. However, the inclusion of plain English explanations proves beneficial.
