Can you guys give some feedback/ideas on my site regarding SEO?

Hello guys, I´ve been a long time lurker. But finally made the decision to join here. I have learn a lot from here, that´s for sure.

Here´s my history. I have been working for a real estate company in Spain since last year, I started as a writer. That was it for that moment, all I did was write quality content, then I started to translate that content from spanish to english. Weeks went by and they liked my job.

Right now they are offering me a few online classes where I can learn a bit of SEO. Now, I don´t only write quality content, I also work on the seo of the page.

I have been building a lot of backlinks since a few months back, I have also made a few 2.0 blogs to get links from too. Lastly, I have worked on the social media too (twitter & facebook). On the last report It seems like the visitors are coming from twitter. Not organic search at all.

I know it´s a really competitive sector, but It seems like the backlinks I have been building for a while aren´t doing a lot of job. If I google search "Real Estate Mallorca" our web is listed at #14. At least, I was able to accomplish that. Because I few weeks ago the web didn't even appear on google.

Could you guys give me some feedback on what I could do to make things go better on the site? sorry for the long post and also sorry if there are typos, I wanted to get all of this out of my head & I am not english native.

This is the web: http://www.villasbroker.com

Thanks in advance!

EDIT: I forgot to mention that I have been working on getting visitors & clients from Youtube too. I have worked on shorts videos of 30 - 50 seconds with the KW of our interest, such as *real estate mallorca* *Propertys Palma de Mallorca* and so on!
