This is a simple question, but one that I think is very important. I own sites that are built on blog platforms, and others that are flat HTML sites. The difference is obviously that blogs are a form of CMS which have category and tag functionality built in, whereas my flat HTML sites are hand-coded and don't have this functionality.
The great advantage of a CMS is ease of use, but the great advantage of hand-coding sites is that I get to change the page format or content layout from page to page if I want to.
My flat HTML sites are larger than my CMS built sites in terms of content, but have less pages indexed than the blog built sites. Consequently the blog sites seem to rank better.
Should I convert my hand-coded HTML sites to Wordpress which will provide category/tag and archive pages even though I'll have less flexibility, or should I simply look at getting more backlinks for these sites?
