I did first , second and third suggestion but no hope ... big fat website scrappers still manage to be on first pages on Google search or Google imgaes. It's became never-ending-agony with them
That's what you suggesting it's more looks like 'stuffing' and we both know that G don't like that at all :/
explanations of using alt tags:
I'm still thinking that google images dont take seriously this madness because I found more website scrappers , ten of them is hurting my rankings on Google Serach and Google Images.
The biggest joke of all is that I reported one of those websites TWO TIMES as thief and after removing my images ... they did it again, scrapping again, both my websites.
Now ... is there effective way to stop this ?
