>The url,title,description and content type have never changed. What did you think the nature of the contents were?
Apparently, because of the category it was submitted to, it was thought to be a site offering the services of a particular real estate agent. Many real estate agents include content about listings on their site (although there is no rule that they have to, it is good business), and many of them submit titles and descriptions similar to yours. It is an understandable error.
>If the target is around the world ,how can that be diffuse.
That's what "diffuse" means -- "no particular place, anywhere"
>If people did not find the site useful,could you please tell me why properties listed sell?
Nobody suggested that a listing on the site could _prevent_ an owner from selling a house.
>Are you saying that when I have a certain number of property listings then i will have a site that you deem worthy?
Yes. That is the definition of "content".
>Are you the editor that removed the site?
It was done by an editor that has more knowledge and experience in that topic than I do.
>Could you give examples of your sites?
Sure, that information is all public knowledge. (Hint: I'm a programmer but not a marathon runner.) But I should warn you that for my own listings I set a benchmark of 5 to 10 times the content that I'd accept from an outside source. It wouldn't be fair to judge your site by that.
You would be better advised to look at the other sites in FSBO categories. Compare their focus and quantity of content with yours. If your site has obviously more than the average number of listings for sites with comparable scope, it is likely to be accepted. If it has no more listings than the smallest listed site, then it is likely to be rejected -- because the other site may have been accepted when it had more listings, or when there were fewer competitive sites.
