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.
Example:
<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%%%%(

/C%766OQQ#OQG6C777%(

/@@O

(@@6@#</pre>
</div>
</div>
or maybe worse, instead of <pre>
element, the ascii art can be composed of consecutive <span>
in <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?
