HTML encryption & SEO

Is it okay?

One of the reasons for considering using HTML encryption is that the files are compressed--in some cases by as much as 70%. The advantage is obvious because of reduced bandwidth usage.

There are some serious drawbacks to encryption (like it requires javascript to be enabled), but there are some advantages (like encrypting javascript and CSS files.)

With the disadvantages aside how does encryption impact SEO? The program I am concerned about is HTML Guardian (Professional version). Has anyone had any experience using the program with any SEO results.

Anyone have experience with HTML encryption and search engine results?

The publisher claims that there is 'a chance' of increased traffic because corporate filters won't work on encrypted files, which suggest that spiders won't read them either. Clarification is needed on this point.

If my suspicions are correct encrypting HTML isn't a good idea, but what about javascript and CSS?

Basically, if you encrypt your page, the search engine spiders cannot read it. If they cannot read it, they cannot index it and any rankings you have or hope to have are gone.

Encryption only works if the pages you want to encrypt do NOT need to be indexed by any of the engines.

Philospher,

Thanks for the info. Much as I suspected.

The only thing I'm interested in encrypting are the javascript files (which I understand spiders cannot read anyway) and CSS files (which spiders ignore).

This might seem somewhat naive, but assumptions are not always correct. When spiders see encrypted material do they just ignore that material or do some of them stop cold and refuse to read the rest of the page? Spiders can be quirky creatures.

They should simply ignore it, but I would be hesitatant to put anything on a page that could confuse a spider. If you are certain that you need to encrypt your js and css info, then it would be much safer to place all js and css into remote files.

That would keep your encrypted files separate from the files that the engines will be indexing and avoid any possible problems caused by encryption.
