Hi all,

I am planning to sell products online for several niches.

I would really appreciate advice on the pros and cons of building one web site with one domain, one web site with several sub-domains (one for each niche) or one web site for every niche.

I am not a SEO expert and I would like to be sure to chose the best option before I start working on the project.

I can think of the following pros and cons at first sight:

1.- Single domain for all the niches:


- Only need to build/promote one site.
- All SEO efforts will be centered in one site.
- Visits from all my niches will be centralized in one web site, which could result in cross sales.


- If the web gets banned you lose everything in one shot.
- Visitors may be confused if they find a single web with very different and unrelated products.
- Search Engines may not like (not sure of this) web pages with too many different and unrelated keywords.

2.- One domain for every niche:


- Visitors will be comfortable in a focused web site.
- Search Engines will find the keywords coherent and relevant.
- Search Engines could not ban all my websites at a time.


- Need to build several different sites.
- Web site promotion must be repeated for every web site.
- Visitors of one niche do not know the other products in which they could be interested.

With respect to sub-domains matching niches, I am not sure if it is a good idea to point each sub-domain to a folder in the single web page in terms of SEO.

This is just non-experienced brainstorming. I would be glad to get ideas from experienced people.

Thanks for your advice.

I used to maintain a directory site for a regional arts organisation. The home page had separate links for artists, venues and suppliers. People searching generically for venues in the region would land on the home page and regularly go away rather than click the link for venues.

For good SEO you want links at topic level. While it doesn't technically matter if these are to domains, sub domains or pages within a single master domain I suspect that other webmasters will be more comfortable linking to distinct domains.

I've moved this from New to web development as it can be a valuable case study that's likely been considered by other SEO's.
