Best SEO audit tools

By Ecombridges    •   Updated January 6, 2024

There are a lot of SEO audit tools on the market these days. So how do you know which one is best suited to your needs? In this article, we'll take a look at the best SEO audit tools and explain why they're worth considering.

On-page SEO versus off-page SEO

It's essential to understand the difference between on-page SEO and off-page SEO:

  • On-page SEO refers to activities you can do within your website to improve its ranking in the search engine results pages (SERPs). It includes improving content quality, optimizing titles and meta descriptions, and ensuring your site is properly indexed.
  • Off-page SEO refers to activities outside your website that can affect your rankings. This includes building backlinks with optimized anchor texts and using social media to promote your content.

What are the Best SEO Audit Tools?

Let's review the best off-page and on-page SEO audit tools, starting with on-page search engine optimization.

On-page SEO tools:

My Take

SurferSEO is the best SEO audit tool for content optimization. It provides actionable insights to help you improve your content quality and make it more SEO-friendly. I use it for all my articles, which helped me get my content to rank better in google.

Key Features

  • Content Editor: This is the feature I use the most. The tool gives you a content score that shows how good your content is compared to your competition on Google. It tells you exactly which NLP keywords to use and how often, as well as the optimal number of words, headings, paragraphs, and images, depending on your selected competitors. You increase your chances of ranking by having keyword-rich and high-quality content.
  • Audit: SurferSEO has a page audit feature that allows you to improve your existing website pages. It shows you where your content is missing out on optimization opportunities. It looks at backlinks, keyword density, word count, page structure, meta tags (title and meta descriptions), load time, and more. The site audit tool analyzes your competitors' content so you can see where you can improve. It's the second feature I use the most.
  • Keyword Research: SurferSEO's keyword research tool helps you find topic clusters and uncover relevant high-traffic keywords to build topical authority. It shows you monthly search volume, keyword difficulty, and related terms.
  • SERP Analyzer: Analyze the correlations between on-page optimizations and rankings in search results.

Find opportunities for featured snippets in a Google search. You can also check the content scores for multiple pages on your website.
  • Grow Flow: it gives you tasks to accomplish every week, such as adding missing target keywords in your articles, inserting internal links, or creating new articles about specific topics.


SurferSEO lets you track and optimize an unlimited number of low-traffic websites. However, it has restrictions on high-impression websites, depending on your plan.

  • Ease of use: It's easy to use and understand, even if you're new to SEO.
  • Integrations: WordPress plugin integration, Google Docs extension.
  • Intuitive interface.
