1.4 Rendering & JavaScript ✦MediumInferred
Content in iframe with no crawlable source
Content inside an iframe is associated with the iframe source, not my page. If that source is not itself crawlable, the content may not count for my page at all.
What it is
Primary content embedded via iframe.
Why it matters
Iframe content is attributed to its source URL, not your page; may not count for your page.
How to fix it
Inline critical content rather than iframing it.
How to find it on your site
- Find iframes carrying meaningful content on the page.
- Check whether the iframe source URL is itself indexable.
- Where the content should belong to the page, render it directly rather than in an iframe.
- Reserve iframes for genuinely embedded third-party widgets.
Cross-reference to ranking and citation factors
Iframed content often does not count towards the host page. Inlining important content keeps the credit where I want it.
Impact
