I have an html site with a page of info for each county in the US. I want to convert this into a new wordpress site. I can do this one by one but my issue comes when I have mass changes to affiliate code or common text. I would have to got to each page and manually change it. but with over 3000 pages it would be way to time consuming. I dont want to use Iframes but would like to know if there is a way to call the html pages into the wordpress page that makes sense seo wise.
I am open to creating a page for each county or have one page with text or buttons on it with each county listed and when clicked will insert the info below. I know alot about static html coding but am new to php.
