I run a job board, which has three different taxonomies; category, location and job type.
I currently have all my category and location pages indexed by Google. They've been in the indexed for many years and rank well.
After requests from our user base, we will soon be creating combination pages. For example, a specific page for Bar Jobs (category) in Melbourne (location).
These will look like:
My concern is that this will create many new URLs.
Should I allow Google to index these pages or will the content difference be too weak?
The H1, Page Title, Meta Description and introductory paragraph or text will all be different to best describe the new pages - but I'm still concerned about best practice.
Secondly, at some point I would also like to introduce job type pages. This again will increase the number of URLs on the site.
domain.com/part-time/ (all part time jobs)
domain.com/part-time/bar-jobs/ (all part time bar jobs)
domain.com/part-time/melbourne/ (all part time jobs in Melbourne)
This could create 100-300 new URLs.
This will also create an opportunity to target many long tail key phrases. I would like benefit from searches such as "part time jobs Melbourne" but I don't want to harm the rest of the site.
What is best practice here?
