Is this Important: Googlebot Indexes the First 15 MB Only

What is Google indexing?

Google indexes pages on the web. This means that it can provide links to those pages in its search results (SERPs: search engines results pages).

15MB is the Google file size limit for a page to be indexed.

This is a major source of traffic for websites, as people who are looking for information on a particular topic often start their searches at Google.

Indexing also helps Google to determine the relevance of a given page to its users.

In the old days, when people used to go to libraries. Google indexing is the library’s index cards.

What is the 15 MB limit for Google search indexing?

Googlebot only sees the first 15 megabytes (MB) when fetching certain file types. This limit only applies to the bytes (content) received for the initial request Googlebot makes, not the referenced resources within the page.

The 15 MB limit applies to fetches made by Googlebot (Googlebot Smartphone and Googlebot Desktop) when fetching file types supported by Google Search.

How does google indexing work in relation to the 15 MB limit?

Googlebot drops the content after the first 15 MB, and only the first 15 MB gets forwarded to indexing.

This threshold is not new; it’s been around for many years.

What to do when your webpage exceeds the 15 MB limit?

The median size of an HTML file is about 30 kilobytes (kB). If your webpage exceeds the 15 MB HTML file size, move the inline scripts and CSS dust to external files.

This is most likely not to affect most web pages. But knowing about the 15MB limit still matters to many who are SEO geeks.
