OP Custom Tag - Other SEO Details

This custom script captures additional SEO details. Under variable summary, select ObservePoint data and under SEO Data is the relevant information.

• metaDescription: Collects the full value of the description Meta tag.
• metaKeywords: Collects all the terms in the keywords Meta tag.
• pageTitle: Shows the title of each URL.
• imageAlt: Shows the caption that goes with each URL.
• canonical URL: An HTML element for each URL that prevents duplicate content problems.
• robots meta tag: Shows which pages have a robot text file. Robot text files instruct search engines on which pages they should crawl.
• h1 - h6: Shows the presence of header tags on each page.

To capture these details in an Audit or Journey, paste the snippet below into an Execute Action:
