Write content for 60 products, 300 words per product.
1) The content must be written in the same flow as the examples above. The content needs to be targeted at the customer and should provide them with all critical information about the drug. It shouldn't be TOO sales-oriented, as that turns a lot of customers off as there needs to be a clear line between health professionalism and sales.
2) The content should be 250-300 words. In that, 10% of the content should be keywords (10% keyword density). The keywords are the drug names, of course.
3) The keyword shouldn't just be placed on an ad hoc basis - the way the keyword is placed in every sentence should actually make grammatical sense and the repetition should be such that your human visitors do not feel that you have deliberately repeated a particular phrase throughout the page. This is not only important from the point of view of ensuring that your readers don't get a bad impression of your site, but also from the point of view of search engine optimization - the search engines may penalize your page for spamming if they find that you have randomly repeated the keyword throughout the page. Also, while repeating the keyword in the page, try to repeat the keyword once near the top of the page and once near the bottom.
4) Make sure that your paragraphs are not too long - each paragraph should be no more than 3 or 4 sentences long. This is because people on the web simply don't have the time or the inclination to read long paragraphs.
