Welcome to the Q&A Forum

Page two correctly uses: rel="prev" href="http://www.buffetdomicilio.com/category/artigos" /> Which indicates to Google it is part of a pagination scheme thus it handles it differently to proper content. You really don't want Google sending traffic to these pages but instead to the actual articles.   In that case, optimizing the title or duplication reduction isn't such a big a deal. It's just one small part on otherwise different pages so you won't get a bad penalty. I wouldn't use the canonical link suggestion as this will effective remove the page from your index.  I assume you want these for spidering so anything that removes them could be an issue.

Hi, Allow me to join your discussion. I just want to make sure I understand it as it is. It will be fine if I have the following images on a single page? For example: Image:Alt pizza-buffet-01.jpg:Pizza Buffet 1 pizza-buffet-02.jpg:Pizza Buffet 2 pizza-buffet-03.jpg:Pizza Buffet 3 pizza-buffet-04.jpg:Pizza Buffet 4 Thank you!

Hey André I'm a little unsure as to your question... but I think you are asking if it is bad to link to internal too many times with the same keywords? If that's the case then yes make sure you diversify the anchor text you are using to link to your pages.
