SEO Tools to Analyze HTML Headings

HTML headings such as H2 and H3 are powerful ranking signals to search engines. Their importance is increasing because Google’s featured snippet algorithm looks for sections of a page to answer a query. Headings help Google better understand the content.

Thus analyzing competitors’ HTML headings and optimizing your own can improve rankings.

Here are three tools to help.

Devaka Tools

Devaka Tools offers a quick (and free) way to identify and extract on-page headings via a bookmarklet, which the site explains:

Bookmarklets are small JavaScript programs that can be stored as bookmarks in a web browser. Unlike regular bookmarks, which simply navigate to a specific webpage, bookmarklets perform actions on the current page you are viewing. They are executed by clicking on the bookmark, triggering the JavaScript code embedded within.

Install on any desktop browser. Then click the bookmarklet in your browser’s toolbar for any page, select “Headings” in the bookmarklet’s controls, and it will highlight all HTML headings.

Thruuu

Thruuu is an AI-powered analyzer of search engine result pages. Type in a keyword, and the tool will perform a SERP analysis that includes images, keywords, and HTML headings.

Use the “Extended view” to access heading information for every ranking page. The “Explore Headings” feature uses AI to pull headings from all ranking pages. Clicking the “i” icon to the right of any heading shows which URLs use it or a similar version.

Thruuu is a helpful tool for understanding competitors’ HTML headings relative to search queries.

Thruuu’s free trial includes 10 SERP analyses. Paid plans start at $13 per month for 75 SERPs.

Surfer

Surfer is a content writing tool using AI to create search-engine-optimized copy. Like Thruuu, Surfer analyzes SERPs for keywords but doesn’t show the details, only the content recommendations.

To use, paste your article text into Surfer with the target keyword. The tool will then provide on-page suggestions — including the number of headings and their keywords — in a guided and clear process.

Pricing for Surfer starts at $89 per month to optimize 20 pages.

Thruuu is more affordable than Surfer and offers a free trial. Plus it provides more details on high-ranking competitors, which I appreciate. Yet busy entrepreneurs and managers may prefer Surfer’s streamlined approach.
