Google has updated the English version of the Googlebot Help. A paragraph has been added to the document in which Google clarified that the bot will scan only the first 15 MB of the page.
A section has appeared in the Googlebot Help document that states:
“Googlebot can scan the first 15 MB of the contents of an html file or supported text file. After the first 15 MB of file, Googlebot stops scanning and considers only the first 15 MB of content for indexing”.
