Before diving in, it helps to know that these two tools show different scores:
Content Editor shows Content Score (the combined optimization metric), along with its two components: SEO Score and AI Search Score.
Audit shows SEO Score only — a measure of how well your on-page content is optimized for traditional search engines.
Because they measure different things and analyze your content differently, some variation between them is expected and normal.
This article covers the differences between Content Editor and Audit. For differences involving Content Audit or SERP Analyzer, see this article.
In Content Editor, Surfer doesn't see your live website — the score is calculated only for the document you're writing at that moment. Guidelines focus on what's actually in the editor: words, images, structure, and so on. Word count suggestions also play a role, since the range of terms to use is calibrated to the current total word count setting.
Content Editor is the only tool that shows the full Content Score, including both the SEO Score and the AI Search Score. The AI Search Score reflects two things: how comprehensively your content covers relevant Facts, and how effectively it answers the user's primary question early in the page (Upfront Intent Alignment).
In short: Content Editor focuses on the document's contents and optimizes for both search engines and AI-powered search.
Audit's analysis is more comprehensive at the page level — it considers everything within the <body> tags of your source code, including your navigation bar, footer, menus, comments, internal links, and meta tags. It looks at the entire webpage, not just the article content.
Another key difference: Audit applies suggestions based on the actual word count of your published page, not a suggested word count. This means terms-to-use recommendations are adjusted to what Surfer finds on your live page.
As a result, the SEO Score, terms to use, and content length guidance will likely differ between the two tools. The tips below can help minimize that gap — but some difference will always remain, and that's expected.
It’s great, especially when comparing their results. It's also important to understand that multi-keyword analysis will be different from the guidelines for a single keyword, as the Audit also does not support multi-keyword analysis. If you have made a Content Editor query using a few keywords (or created one from topic clusters in Keyword Research), the Audit won't show you the same results in a query made for only one of them.
The SERPs may vary depending on whether we are crawling it for mobile or desktop devices, so it's important to choose the same crawler for both tools.
Since Surfer's suggestions are based on top-performing pages, if the top results change, so would the score and terms to use. If you are running an Audit and a Content Editor, you must remember to check and select the same competitors to get comparable results.
SERPs are dynamic and are changing daily. Depending on the niche, those changes may not even be noticeable, and some may be very substantial. When you are running an Audit to optimize your article written in your Content Editor a few months ago, you will most likely see some differences, even if you choose the same parameters to run both queries. And it's totally ok! That is the main purpose of our Audit tool - to let you stay relevant and keep your articles up to date.
If you add some changes to your Content Editor article outside of Surfer, Audit will be able to see those changes, but Content Editor will not. For example, let's say that you created your article using Content Editor but decided to add your hyperlinks directly to your website-building tool. That would cause Audit to ignore the hyperlinked terms in the published article, but Content Editor would still see those.
