Think of it this way: The more specific your content, the more specific the needs of your audience are -- and the more likely you'll convert this traffic into leads. This is how Google finds value in the websites it crawls; the pages that dig into the interworkings of a general topic are seen as the best answer to a person's query, and will rank higher.
See the screenshot below for some of the sections for specific recommendations that you can add which will provide the meat of the document. Keep in mind this is a very flexible document – add recommendations that make sense (for example you may not always have specific design considerations for a project). Remember, it will be different every time you do it.
To gain more customer engagement, the website must reach its visitors/customers efficiently. Obviously, you want the visitors to read your site content. Check the forms and click through on your Call To Actions (CTA’s) when they arrive on your web page. These features initiate user engagement in action, but it is essential to comprehend the in-depth analysis.
I’d add one thing to number 5: Writing good copy is crucial not just for your Title/snippet, but for your whole page, especially your landing page. You want people to stay on your page for a while and (hopefully) even navigate to other pages you have. Google looks at bounce rate and where they go after they hit your page. Learning to write good copy can not only increase conversion (if you’re selling something) but make your content more impactful and engaging. There are free books at most libraries or online to help.
As I had a teacher at school who was always really picky on how to draw conclusions I must say that the conclusions you drew for your health situation might be true, but dangerous. For example: If slightly more women than men suffer from health deseases it could be wise to write the information toward women. But, if you take search behaviour into account thing could look a lot different: It might turn up that men search more than women or that (senior) men are more present on the net than women.
Backlinks. If content is king, then backlinks are queen. Remember, it's not about which site has the most links, but who has the most quality links pointing back to their website. Build backlinks by submitting monthly or bi-monthly press releases on any exciting company, and contacting popular blogs in your niche to see how you can work together to get a backlink from their website. Create the best possible product site you can, so people talking about the products you sell will link back. Try creating graphics or newsworthy content that will influence bloggers and news websites to link that content.
Search engines use complex mathematical algorithms to interpret which websites a user seeks. In this diagram, if each bubble represents a website, programs sometimes called spiders examine which sites link to which other sites, with arrows representing these links. Websites getting more inbound links, or stronger links, are presumed to be more important and what the user is searching for. In this example, since website B is the recipient of numerous inbound links, it ranks more highly in a web search. And the links "carry through", such that website C, even though it only has one inbound link, has an inbound link from a highly popular site (B) while site E does not. Note: Percentages are rounded.
