Build a Search Engine driven website

This website will be used to generate a local, perimeter based location, website service, for a specific question asked of a Search Engine. The topic, and other keys of the question will dynamically adjust the content. This website will also have a domain name that contains the topic, or other keys.

This website will have a need to get a response from a public API. Then use that response to construct its content.

The developer should assume:
That there will be 50 or more Domain Names that are directed to website.
That the customer will configure the delivered setup structs/tables to enable a new Domain Name, for website.
That the customer may wish to change the source of the API, that provides the details for the content to a similar service, for website. The developer should use his/her best effort to make this a manageable task for the customer.

Websites are to be delivered with html meta tags for pages, sections, paragraphs, images, titles. The developer may incorporate more.
Websites are to be delivered with Structured Data.
Websites are to be delivered with Open Graph Tags
Websites are to be delivered with Twitter Meta Tag Cards.
