1) Keywords must be in English. We automatically translate keywords into eight other languages, so you, as the submitter, should always submit your keywords in English.
2) Keywords must be relevant to the image. As stated in Part One, the most common example of this is using the keyword sun in any submitted content without an actual sun in the frame. Just because the image was taken in daylight does not mean the keyword sun should be used at all. Always think relevancy for your keywords.
3) You may change keywords after uploading a photo for review. You may also add keywords after an image has been approved. However, your keywords still must be relevant as we regularly audit keywords on a daily basis. With this in mind, any attempts of keyword spamming after an image has been approved will be caught and dealt with accordingly. Keyword spamming is not tolerated.
4) Keyword-spamming: Using unrelated keywords for an image will not increase your sales and is actually counterproductive. It will cause unrelated image search matches and drive subscribers away from our site – something we do not want to see happen. Example: using the keyword feline or cat for an image of a dog. Remember, use common sense and do not keyword-spam. If you do, your account will be disabled.
5) Each image must have a minimum of seven keywords for the image to be reviewed. Make these keywords count!
6) For multiple words where you would like to create a unique phrase, consider using quotation marks. Example: clay pot. Depending on whether quotation marks are used, this phrase can be understood as two separate keywords or one keyword. In response to clay pot our search engine would only return an image if both clay and pot are separate keywords associated with the image. Now, if someone wanted to treat this keyword as a phrase, they would place it in quotations, "clay pot.” The search engine would then return all images where the phrase "clay pot" was used as the keyword. It does not return images which only used the individual keywords clay and pot.
6a) Another example would be: African American. Again, for the best hit ratios, you should use the following examples as keywords: African American (no hyphen and separate words), African-American (with hyphen) and “African American” (using quotations. Remember: Keywords in quotations are considered unique phrases) – following the same thought process as above.
7) The keyword cupcake is one keyword. You may use cake as a separate keyword, but not cup as a single keyword. Again, think relevancy.
8) Singular vs. Plural: When using the keyword cupcake, it is okay to use the singular version alone as a keyword. Why? Our search engine automatically associates and searches for plural versions of words, so in this example, it is not necessary to keyword cupcakes.
Remember, Keywording is very important for your sales, but it is also important that our subscribers get the best relevant hits during their searches.
