# Producing a large number of consistent pages from a single source

> Producing a large number of consistent pages or mini-sites from a single data source, rather than building them one by one, is a type of project that pays off once page volume exceeds what manual building allows.

## The typical need

Some projects need a large number of pages or sites that share the same structure but differ in content: a page per venue, per city, per product, or a full site per client in the case of a multi-tenant solution. Building each page or site by hand quickly becomes unmanageable beyond a few dozen units, and introduces a risk of inconsistency between them as things evolve.

## How I approach this kind of work

The principle is to clearly separate structure (the template shared by all pages) from data (what varies from page to page), and to generate the pages or sites from that combination. It starts with precisely modelling the data source: which fields are required, which are optional, how missing data is handled without breaking a page's rendering.

A point often overlooked on this type of project is SEO: generating several thousand nearly identical pages, with no genuinely differentiating content, can produce a result that search engines penalise rather than reward. I pay particular attention to real content variation between generated pages, and to setting up mechanisms that prevent publishing pages too thin on information.

## Factors that affect the estimate

- **Quality and completeness of the data source** — A source that's already clean and structured greatly reduces preparation work compared with heterogeneous data that needs normalising first.
- **Number of templates required** — A single template reused everywhere is simpler than a layout that varies by the type of entity represented.
- **Update frequency** — A one-off generation is a different problem from a system that must automatically regenerate pages every time the data source changes.
- **SEO requirements** — Genuinely differentiating content between generated pages takes more design work than simply substituting variables into a template.

## Questions to ask before starting

> Is the data source rich enough to generate genuinely differentiated content per page? How many different templates are actually needed? Do pages need to regenerate automatically, and how often?

## FAQ

### Does this kind of generation suit a small number of pages?

The benefit becomes clear from several dozen pages upward; below that, building by hand is often quicker to set up than the generation infrastructure.

### How do you avoid generated pages being penalised for thin content?

By making sure each page brings information genuinely specific to its subject, rather than just a name swapped into otherwise identical content.

### Can pages update themselves automatically?

Yes, that's an architectural choice to make at the design stage: automatic regeneration on every source change, or one-off generation with manual updates afterwards.

### Does this approach work for full multi-tenant sites, not just pages?

Yes, the same principle extends to generating complete sites per client or entity, each with its own configuration, from a shared technical foundation.
