JavaScript: Contains JavaScript Links

Pages that contain hyperlinks that are only discovered in the rendered HTML after JavaScript execution.

These hyperlinks are not in the raw HTML.

How to Analyse in the SEO Spider

Enable JavaScript rendering mode via ‘Config > Spider > Rendering’ and select ‘JavaScript’ to crawl JavaScript websites.

View URLs with this issue in the ‘JavaScript’ tab and ‘Contains JavaScript Links’ filter.

Identify which hyperlinks are only discovered in the rendered HTML after JavaScript execution by clicking on a URL in the top window, then the lower ‘Outlinks’ tab and select the ‘Rendered HTML’ link origin filter.

They can be exported in bulk via ‘Bulk Export > JavaScript > Contains JavaScript Links’.

What Triggers This Issue

This issue is triggered when pages contain hyperlinks that are only discoverable in the rendered HTML following JavaScript execution, and are not present in the raw HTML.

How To Fix

While Google is able to render pages and see client-side only links, consider including important links server side in the raw HTML.
