Hide some text from spider (for seo purpose)

[basketmen]

guys, i want to hide some text just from spider, but real people guest still can see it, this is for seo purpose


for example i want to hide text from this hack Welcome headers - Improve community registration rates , some people make the text as image so spider cant read it, but its better if we can just hide it from spider




is this code right to make like i say above?

<if condition="$show['spider']">

</if>
