Keyword: A word that people type into a search engine to find websites that relate to the word.
Keyword Phrase: Two or three words in a string. Some examples – “educational toys,” “children’s books,” “wooden boats.” Generally, a noun (person place or thing) and one or two adjectives (words that describe the noun).
Keyword Proximity: When two or three keywords are placed together and how close they are together. For instance – “educational books” v. “educational children’s books” v. “educational children’s monster books” You would want words to be placed together when you think that people would type them into a search engine exactly that way – a keyword phrase.
Keyword Frequency: (Also termed “Keyword Density.”) The number of times a keyword or keyword phrase appears in the text of a web page (can also include the keyword in the title, meta tags, and alt tags.) I will refer to this as a percentage. Keyword/Total Words in Text=3% or Keyword/Total Words in Text, Title, and Tags=5%
Stemming: You will notice that when you type in plural like “toys”, the suggestion box will change it to “toy”. This is because GoTo will read only the root of the word. The term for this is called “stemming”. We will discuss this term more when you are writing your keywords tag and keyword frequency in the text.
Stop words: You will also notice that no words like a, and, the, of, that, it, too are used. These are called “stop words”. Some engines will index them and others won’t. You will find out which ones do and don’t on the SE specifics page.
