This is a technique
to hide the source code on web pages. There are two main reasons you
might wish to do this.
1) to hide the code
so your competitors cannot see it. If you are a typical small business
it is unlikely you have much technical wizardry to to hide, that an
internet expert could not figure out for themselves
2) more commonly,
cloaking software is used to show one set of code to search engines,
and one set to browsers. Thus you show text and meta data that you think
the search engines will rank you highly on (which might be virtual gibberish)
and show coherent text to the human visitors.
We would not advocate
the use of cloaking software, as:
1) its a trick,
and the search engines will keep on development to avoid these tricks
2) it makes page
development even more complicated
3) you can, in most
circumstances work out a compromise between use of good key terms in
your tags and text, without loss of comprehension in the text.
4) the use of cloaking
software may be associated with "adult" sites, scams etc.
Instead we would
advocate the use of the various techniques we describe on the pages
in Marketing Strategy and Promotion.
