OK so you're only doing Jordan tours. And you're not doing other things that would require you to make sub folders, such as tours, hotels, flights. Do keyword research to make sure exact match "jordan tours" is your main target and not "tours in jorden" for instance. Also feel free to mix it up I would think that your C option is the best, since the keywords in the filename is better for SEO than in the directory www.yoursitewithoutkeywords.com/ www.yoursitewithoutkeywords.com/jordan-bike-tours www.yoursitewithoutkeywords.com/5-day-inclusive-tours-in-jorden
