For SEO, "Content is King". I wonder what would be the SEO cost of garbage text inserted between descriptive content.
The case I have in mind concerns ascii art. Such page would contain consecutive blocks containing a description of the ascii art, followed by the ascii art itself.
<div class='asciiart'> <div class='description'>here is an hideous kitty</div> <div class='ascii'><pre> (%(// (6%( /%7%CCGG66%%C (%7%%G#QO%C%( /%7%%%OOGC777%/ 77(%G6C6GQ%(%/ C67%%776%7%%% (O%OGQQ#GCC (77%G6CGQG%( 7%%%%%GQ%%C%/ (%77%%GQ6%%%%( /#O((%GQGGG%%7( O%7%%%OOGC%%%%( (%%77%CGQ@Q%%%(%%/ /C%766OQQ#OQG6C777%( 7%C7%%6GGQGQO6%%%%7% (7%77%OQ@Q#@#QC%((%%%/ (7%7%%GG(%OQ#Q#QGC%77/ 7%77%6OOGQ@#%O6%(7%%/ /77%%6GQ@#QCOQGCO%%( /(%C6G##@@QOO%%%/ ///(O@#@(/(/ /#@6/ (GG#/ /@@O /@@6 Q@O ( /O@O @@6 /(QQ@@ (@@6@#</pre> </div> </div>
or maybe worse, instead of
<pre> element, the ascii art can be composed of consecutive
<div> in order to set different colors to each part of the art.
In both case, the page is full of textual data that are non-sense for a search engine. If this implies a negative impact on SEO, is there a way to tell the search engine to ignore these garbage parts?
