A good link is usually either : * A complex phrase - e.g. There is no such thing as a free lunch. These are easy to recognise, because they are long (typically 3 or more words). * A proper noun - e.g. North Sydney, Anthony Albanese. These are easy to recognise, because they are capitalized, whilst not being at the start of a sentence. * An acronym - e.g. NAFTA is a free trade agreement. These are easy to recognise, because they are capitalized in multiple letters. Then there are things that are sometimes worthwhile linking on: * Abstract nouns - refers to ideas or concepts - e.g. fraud can be a good link, whereas government is probably a bad link. Determining which abstract nouns make good links is hard, although we can make some broad generalizations (e.g. abstract noun words that end in "-ism" tend to be good links, such as fascism). * Adjectives - e.g. blue-collar is a good link, where as the blue in the phrase "the sky is blue" would usually be a bad link. Determining which adjectives make good links is hard, as the best links are to infrequently used adjectives (some of which are on this list). Things that are usually bad links: * Common nouns - e.g. restaurant, chair, bed. * Verbs - e.g. to be, suggesting. * As a rough rule, very short links tend to be bad. These are easy to recognise, by rejecting any links less than say 4 or less characters long.
