High search volume keywords

[bele]

The problem is that our index is not in serps anymore with the high volume keywords (Pfizer, Roche, johnson & johnson).
We still keep these keywords in title, but it brings not much results.

We made page www.domain.com/pfizer , added there Pfizer products with unique descriptions.
Product pages started to drive visitors, but not the www.domain.com/pfizer page.

If we add a blog to the top of this page and add unique posts about Pfizer company news, would it help?
In this case this page would be unique, refreshed with new info, and have rotating pfizer products.

Maybe some other suggestions?

The first place I would start is by looking at what links you have to that page using OSE - http://www.opensiteexplorer.org/.

If you don't have many decent links to that page you need to start looking at ways you can build these links through methods such as competitions, social media (build an audience/following and build relationships with authority figures for your niche, then you can put your great content in front of them for the exposure and links will come), informative articles about the brand and products, etc. There are lots of decent ideas and guides to building links on here so I won't reiterate them, just search for link building on here.

You also need to look at your domain authority and how many decent links you have for that. Essentially on-page factors only act as a guide to what your content is about but links indicate this information is worth reading so improving you link profile will increase your rankings for keywords.

Remember

Great content + exposure = links

Links give authority and help increase your rankings in the SERPs

Hope this helps
