Hi
I have a question about key words. The key words that show up below my articles are different than the words I entered in the submission form. I am assuming that a computer program selects key words based on percentages within the article. If that is the case, why are we asked to submit key words?
Thank you.

The keywords we submit with articles are used with the search function. If anyone looking for the right article to buy searches on one of your keywords, your article will be listed for them to check out. You'd be wise to put in as many possible variations of search terms as you can think of for each article - a little extra work that is well worth while.
