With 100,000's of property websites it's hard to know who to count in the top 10 and for which category. Many leading websites are run by newspapers or publishing houses that create large amounts of content quickly and drive top level traffic to their sites using a variety of paid for and organic searches. Many top 10 property sites only have regional or local traffic and little to no international traffic.
What does it mean to be listed in the top 10 of property websites? Size, search traffic, location, number of properties listed, results, agent levels, owner appreciation, response time? If you are looking for a list of the top 10 property websites for international traffic the keyword to use is international property and within the first few pages of the search results it's likely to be able to findaproperty that will fit a buyer or investors needs and be ranked in the top 10.
