Welcome to the Q&A Forum

At the risk of sounding too repetitive, I'd advise against this: And that's what I'm looking for: a few good articles mkt sites (3-4) to put some good articles on. That's what the client can afford now and I'm sure it is better then nothing. If you find a site that will allow just anybody to post to it and link out to their clients then it's either not going to pass much link equity or be a site that is on Google's radar as a low quality site that links out for SEO purposes. Now, I do believe that it is possible to strategically connect with the owners of quality websites and find ways to either provide content for them or offer them something of value on your clients' website that will make them want to link to them.  But, this is not something you can do at scale.  And you have to be really careful. What I do for the majority of my day is deal with websites that have been either penalized or algorithmically demoted because of link schemes gone bad. I can very easily spot a link scheme vs earned links. If I can spot these, then I'm sure Google can. If you're looking for a list of great sites that will allow you to post articles freely and add value to your clients, they likely don't exist IMO.

thanks Irving I am targeting to google.com.br, and I also think that would be better to use the stress from a user experience point of view, because it is simply not correct to write portuguese words without stress. But I'm measuring many more researches in google.com.br for keywords without stress. That means that brasilian people use to search words in google without stress. This lead me to think that it would be better from a SEO point of view to use keywords without stress. Any other point for one solution or for the other?
