thanks for your reply you're right that it's common but it's still wrong according to the manual of style links should only be included if they're useful to the user too many links are distracting it's not useful to link every possible word when there's no doubt about its meaning so to take a cricket example if you write he played his first test match in it's useful to link test match because people might not know what a test match is and might want to follow the link to look it up but it's not useful to link because everyone knows when was so the link doesn't help anyone but you don't have to take my word for it this is explained in detail in wikipedia make only links relevant to the context and wikipedia manual of style links thanks
