SEO Copywriting is the technique of writing the viewable text on a web page in such a way that it reads well for the surfer, and also targets specific search terms. Its purpose is to rank highly in the search engines for the targeted search terms.
As well as the viewable text, SEO Copywriting usually optimizes other on-page elements for the targeted search terms. These include the Title, Description and Keywords tags, headings and alt text.
The idea behind SEO Copywriting is that search engines want genuine content pages and
not additional pages (often called "doorway pages") that are created for the sole purpose
of achieving high rankings
