I consider some of the SEO spam to be an irrelevant subject.
There are three parties involved:
- Google. From their perspective, everything which doesn’t follow their rules, maybe SPAM.
- The visitor. Considers to be SPAM some things, for others – not.
- The web site owner. Wants nothing to be considered as SPAM.
From my perspective, the visitor should not be focused on SEO SPAM done on a web site, but which doesn’t affect the viewership. So, if a web site owners decides to still use meta keywords tag, and actually SPAM this tag, it’s his problem.
I don’t see why anyone would accuse a business – “You do internal SEO SPAM with those internal keywords”. In my opinion, if they’re not clearly visible actions, the visitor should not focus on SEO SPAM.
Practical case – I wrote an article:
Should the visitor of my website care if I put titles and subtitles in h1 and h2 tag or not? Would they be hurt for this? No. OK, in my opinion, then, I am not SPAMming, or, more precise, it is irrelevant whether I SPAM or not for the regular visitor.
Note: in the above article there was no clear intention of SPAM, but I was accused of such.
