Welcome to the Q&A Forum

Hi Miguel, Aside from whether or not this is good for your SEO, you should also consider whether or not this is good for your customers. Based on a loose translation, it seems that this content would provide little to no helpful value for your users, so it's safe to assume Google would treat it the same way. Instead, focus on developing more comprehensive content that clearly explains the products you offer and the reasons for purchasing these products from your site vs. one of your competitors. You definitely came to the right place if you are learning SEO - and you should definitely check out Moz's beginner's guide to SEO or Google's keyword stuffing guidelines. Good luck!

If you have 50 internal links on a page and NoFollow 25 of them, the link equity is still divided by 50 before being passed... but the NoFollow means those 25 get nothing and the followed 25 only get 1/50th.

If you are selling blue widgets then you really only want people that are looking for blue widgets, no use directing people who are not interested. As for ranking No, it will not help. What does help is and sort of related, is clicks from search engines, Bing and now Google track users that use the search engine in the way that. If a user goes to Bing or Google and searches for blue widgets and clicks on result #1, then returns and clicks on #2, and does not return, then that is a signal that #2 is a better result for the search term. if this happens enough then #2 will replace #1.
