Copywriting for enhancing the search engine placement of your pages is a time consuming and tedious task.
The trick is to write page text that both human readers and search engine spiders and bots like.
This kind of copywriting focuses upon writing where between seven and 15 percent of the words in the body text of the Web page are key words.
There is a key words section in the "Meta Tag" area of the page (in the "Head" section of the page document.
But, some search engines, especially Google™ don't use the key words in that section any more. Instead, the Google™ spiders determine their own key words based upon the information that is on the page.
This strategy is more apt to provide relevant information about what the page is about, and, in turn, make the searching person feel happy about Google™ enough to search with Google™ the next time.
This need to weave key words into the text in a way that the stilted style doesn't look that stilted is another reason that SEO copywriting takes many passes through the document (edits/ drafts).
