There is something very important to have in mind regarding the ranking of your website in the search engines results; it is not enough to rank well for a certain keyword, the really important thing is that people actually search using this particular keyword.
What if you rank first for "large furniture company Greece"? Do you think it really matters? Do you believe someone might actually search using a term like this? If you were searching online for furniture for your home, would you be using a search term like this? Hardly.
The company that optimized your website might be trying to convince you what a fine job they did and got you in the top rankings but the truth is that a keyphrase like this is way too specific, in such degree that it is actually useless. And, by the way, it is not very difficult to make a website rank #1 for such a keyphrase.
The statistics of your website can be a good eye opener. Study them carefully and see if there are actual visitors coming to your websit by searching for the particular keywords or keyphrases that you rank well for.
If not, study the facts, decide if these keywords are useful or not, and then act accordingly.
