oncrawl SEO basics

Our data

HTML tags are important to optimize your SEO. They allow you to categorize your content and highlight important parts. Hn tags can stress out pieces of content that need to stand out to Google’ eyes and to your readers. OnCrawl has integrated these data in its SEO crawler.

In your ‘Content’ tab you can access a ‘Main Tags’ subcategory.

Good practices to HTML tags

  • Write unique Hn
  • Insert your main keyword in your H1
  • Avoid writing more than 10 H2
  • Prefer between 2 and 5 H2
