I would like to add an ASCII Art signature (about 4000 characters) in a comment at the top of my webpage with my website link and a small strapline in it. This would give people looking at the source a little treat and let them know who built it.

Would there be any impact for SEO in doing this (plus evidence)?


Comments are ignored by the search engines so this will have no impact on your SEO.

  • Thanks for the answer, I heard Google only parses a certain amount of characters - does that include the comments or not? – Chimoo Mar 24 '12 at 17:47
  • @Chimoo: Where did you hear that? – Ilmari Karonen Mar 25 '12 at 2:08
  • Google will read up to 100k of a file before they stop parsing it and that includes comments. But unless your pages are huge this shouldn't be a problem. If it is, you need to re-evaluate how your content is being presented. – John Conde Mar 25 '12 at 2:44
  • Please note that the 100kb crawl/download limit only applies to the "Fetch as Googlebot" tool, and robots.txt instructions. Google has stated that the Googlebot fetches much more on several occasions. – Mike Hudson Mar 25 '12 at 22:17
