301 redirection for e-commerce website

[russellbrown]

Hi moz community,

I am the web agency for a e-commerce website. Its current domain is https://www.liquorland.co.nz but now all the e-commerce part will be moved to a sub-domain https://shop.liquorland.co.nz. There are thousands of e-commerce current being indexed in Google (i.e., 15,500) plus they also have a mobile version of the page like /mobile/default.aspx.

Is it necessary to 301 redirect all the pages? We are afraid it may slow down the website because the request will go through thousands of filters. Is it OK to just redirect the main categories?

Many thanks in advance.

Hi Bernadeete,

Thanks for your reply.

The problem for us is that the URL may also changes not just subdomain. e.g.,

https://www.liquorland.co.nz/product1.aspx --> https://shop.liquorland.co.nz/product2.aspx

The current domain www.liquorland.co.nz will be hosted on a new CMS and direct people to the e-commerce part which now has moved to shop.liquorland.co.nz.

We are thinking about redirecting just the main category pages because too many redirection rules as our developer said may hinder the website speed. But I am just worried without proper 301 redirection for many other pages, it may have a negative impact on its organic performance although i am not quite sure how big impact this would be.

Would it be helpful if i redirect all other pages (so there will not be any complex filters to slow down the website?) to the homepage?

Thanks a lot.

Russell, I'm assuming that you are going to move just the subdomain--and pages on the site. So, you would be doing something like this:

https://www.liquorland.co.nz/page.aspx --> https://shop.liquorland.co.nz/page.aspx

If that's the case, then typically you wouldn't need to load in a separate 301 redirect for each and every page on the website. You should be able to use one "blanket" 301 redirect that moves from the www subdomain to the new shop subdomain.

Keep in mind, though, that you really shouldn't have to be moving at all--and that is the ideal situation. If you're move to another server or another CMS, then you should be still able to use the www subdomain and not change URLs. If you have trouble and still would need to move, then consider using ISAPI Rewrite to take care of this.
