are my keywords too difficult

Your keywords are okay. I agree with thusharaherath. Do link exchange for good position in search engine.

I think for this keyword is too generic, it quite difficult. That require number of links.

Try social Bookmarking websites, Make a cool video of your website and submit to video sharing websites, get more backlinks from related websites.
It will gradually increase your SE position along with traffic.

Good luck!

Keywords are ok, and I also recommend link building towards relevant websites. Keep away from paid linking and bad directories with no relevance.

Focus on long tail traffic.

am trying to rank highly in all search engines for the keyword holiday rentals, why i can't i get there, my website is http://www.costa-blancarentals.com

Your targeted search term is very competitive, I suggest you start picking specific KWs that are easy to target. Those long-tailed keywords that has high traffic but less competetition.

Is it worth just stealing everyone elses tags? I dont know how much success that would bring but it seems logical
