How are SEO articles usually linked back to the target site (where the actual product is sold)?
When I look at samples, most of the times there is no link to the target site.
Will the URL be only in the “bio” section of the author?
Right – most article directories only allow links in the author’s resource box. If you’re just looking for the SEO benefit of the backlink just about anything in the resource box will do but if you’re looking for good click through rate with human visitors I’ve found that splitting the article into two parts with part one on the article site and part two on your site works well. Tips articles are good for this – put half your tips in the article then your resource box would link back to your site with something like “for 5 more tips on [keyword link] check out [url link]“.
