He has 4 sites on different products (supplements and equipment) he used to recover which are popular among alternative health professionals.
I want to use the RSS/blog(s) to improve his search engine rankings. 1 site does extremely well for its phrase and doesn't need a boost because it is #1.
1 site has stiff competition and needs a boost. The 2 others are in the Google sandbox since they are new.
Trying to decide between 2 options:
Option 1. One RSS/blog on general information for recovering from the health crisis including things he is learning with links to his sites when pages change.
Option 2. Three RSS/blogs for the 3 sites focused on the 3 key phrases.
Option 1 is certainly easier but people interested in one phrase may not be interested in others. Of course, continued exposure may get them interested in the benefits of the other products.
What do you all recommend if my goal is a search engine boost?
A blog is a way to create content. This will give you whatever natural SE rankings it deserves - it all depends on the content.
By using an RSS feed of your blog, it will allow other people to put your content on their site. Your content will have to be good for other people to be willing to put on their site.
Normally an RSS is about a subject rather than a keyphrase.
Just having an RSS feed will not boost you in any search engine unless the query is specifically for a .xml/.rss file and there is no competition.
So, like eurotrash said, if you've got good content then others may use it. The feed file itself won't be a ranking factor on most SEs.
