I wonder if it is OK to make some paragraphs of the content of my landing page to be images? (it is no problem to make it and it looks just like it's a text). However, is this even allowed? I'd like to do it to improve my landing page quality score and improve my CPC. Isn't this called black SEO?
No, it's called ANTI-seo. Search engines can't read text in images (SEO refers to natural/non-paid search results). And no, it wouldn't help your QS in AdWords at all, it'd just hurt it.
Unless he put the "alt" tag to his common keyword then he wouldn't feel the brunt so hard. But why would you want to place text inside an image unless you DONT want Google to read your text of course - which would mean you were trying to fool them in some way which would mean you would get slapped sooner or later ;-) Cheers Stewart
Well, yeah. I wanted to hide those part of the content that don't contain the keywords on which I'm bidding on Adwords - in order to get better quality score = to improve my CPC. But OK, I won't do that, as you said it's fooling, so they would find it out. Thanks for replying guys.
