Anatomy Of A Domain Name and URL

  1. 1. Anatomy of a URL by Andy Wibbels http://andywibbels.com/
  2. 2. A web address has many parts.
  3. 3. Understanding which parts do what can help you better understand how your readers and search engines see your site.
  4. 4. www.yourdomain.com Here’s a domain name.
  5. 5. www.yourdomain.com Let’s break it down into its many parts.
  6. 6. www.yourdomain.com That thing on the end? That’s called a Top Level Domain.
  7. 7. Common top-level domains .com .net .org • For • For internet • For non- commercial service profits entities providers .edu .mil .gov • For • For military • For US educational use gov’t institutions bodies
  8. 8. Each country has it’s own top-level domain: .uk .ch .ph .th .us .tv .ca .au .cc .sp .fr and so on… Full list at http://en.wikipedia.org/wiki/Country-code_top-level_domain
  9. 9. www.yourdomain.com So that’s the top-level domain, the part after the ‘dot’ and before the ‘everything else.’
  10. 10. www.yourdomain.com Let’s take a look at the part ‘between the dots.’
  11. 11. www.yourdomain.com It doesn’t allow spaces or underscores.
  12. 12. www.yourdomain.com www.YourDomain.com www.YOURDOMAIN.com It is not-case sensitive. All of the above go to the same place.
  13. 13. www.your-domain.com You can have dashes.
  14. 14. www.yourdomain12.com Or numbers.
  15. 15. www.yourdomain12.com Together with the top-level domain. This is what most people mean when they talk about ‘a domain name.’
  16. 16. www.your-domain12.com www.your-domain12.net www.your-domain12.org www.your-domain12.au These are all different domain names, that might be owned by different people.
  17. 17. www.your-domain.com So that was the part ‘between the dots.’
  18. 18. www.your-domain.com Let’s look at the part ‘before the dot.’
  19. 19. www.yourdomain.com The part before the first dot is called the sub-domain.
  20. 20. www.yourdomain.com Yes, you’re right. It doesn’t make sense that it is ‘sub’ and is first as you read it out loud.
  21. 21. www.yourdomain.com Make peace with that.
  22. 22. www.yourdomain.com mail.yourdomain.com blog.yourdomain.com stuff.yourdomain.com Sub-domains allow you to channel different bits of traffic to different parts of your company.
  23. 23. www.yourdomain.com mail.yourdomain.com blog.yourdomain.com stuff.yourdomain.com All of these sub-domains are controlled by the same person that owns the domain name.
  24. 24. www.yourdomain.com The default is ‘www’ for ‘world wide web.’
  25. 25. www.mail.yourdomain.com A common mistake is adding the ‘www’ if there is already a domain name.
  26. 26. www.mail.yourdomain.com That isn’t necessary and may cause weird error messages.
  27. 27. yourdomain.com = www.yourdomain.com Depending on how a site is setup, you don’t have to type in the ‘www.’
  28. 28. yourdomain.com ≠ www.yourdomain.com Other times they are different. This small detail may drive you batty when troubleshooting so be vigilant.
  29. 29. www.yourdomain.com So: sub-domain.
  30. 30. www.yourdomain.com Domain.
  31. 31. www.yourdomain.com Top-level domain.
  32. 32. www.yourdomain.com Usually referred to as one big thing called ‘a domain name.’
  33. 33. http://www.yourdomain.com So what’s this H-T-T-P business?
  34. 34. http://www.yourdomain.com There are many ways for you to connect to a website.
  35. 35. http:// The most common used by browser is Hypertext Transfer Protocol
  36. 36. http:// Hypertext is a nerdy way of saying ‘web site stuff.’
  37. 37. http:// The http:// tells the web server how to respond to the request to view a particular web page or file.
  38. 38. http:// The colon and 2 forward slashes just make it look fancy.
  39. 39. http:// Yes, the direction of the slashes matters. If they lean to the right – into the direction you’re reading, they are forward slashes. If they lean to the left – they are backslashes.
  40. 40. http://www.yourdomain.com Another piece of the puzzle!
  41. 41. http://www.yourdomain.com/stuff Uh-oh. What’s this?
  42. 42. http://www.yourdomain.com/stuff This tells the website, I want to see your folder of stuff.
  43. 43. http://www.yourdomain.com/stu_ff http://www.yourdomain.com/1 23 http://www.yourdomain.com/FuN This folder on the webserver can be case sensitive and can contain spaces and underscores. It is separate from the domain name system.
  44. 44. http://www.yourdomain.com/stuff This part points us to the server. This part tells us what to get once we’re there.
  45. 45. The path to these files can be as long as it needs to be. http://www.yourdomain.com/stuff/something/important.pdf This part points us to the server. This part tells us what to get once we’re there.
  46. 46. http://www.yourdomain.com/stuff.xls This tells the website, I want to see a spreadsheet called stuff.xls.
  47. 47. http://www.yourdomain.com/stuff.htm This tells the website, I want to see a webpage called stuff.htm.
  48. 48. http://www.yourdomain.com/stuff If there is no file requested – just the folder – the server may respond with the ‘index’ of that folder.
  49. 49. Sometimes a URL has variables in it that tell the site what to do. Here is the full URL to my Facebook profile. http://www.facebook.com/profile.php?id=505504719 The browser talks to Facebook and asks for the the profile.php file is a profile.php file script and looks for a variable called ‘id’ and that is how it knows what Facebook profile to show.
  50. 50. But at the end of the day, the important thing to remember is this:
  51. 51. www.yourdomain.com Sub-domain.
  52. 52. www.yourdomain.com Domain.
  53. 53. www.yourdomain.com Top-level domain.
  54. 54. www.yourdomain.com Usually referred to as one big thing called ‘a domain name.’
  55. 55. Thanks! Let’s connect: http://andywibbels.com/
