Page Load time increased (domain)

I would try and reduce your 28k regex redirects, which is an unusually high number to have. There must be a more efficient way of redirecting your old site, and plain redirects will perform better.

It is a lot I know, we have moved ecommerce site and the previous site had some really bad ways of producing links:
– multilang
– mobile version
– other versions

a single product page for example could have as many as 10 or more individual URLs, the easiest way to preserve the SEO for these was to just regex the unique code at the end of the url. I will try to reduce them until the new site structure is properly crawled we are sort of stuck with using redirects, it adds a hell of a lot of time 3-4 sec on the domain load – which is completely unacceptable.

If there is a way of programmatically mapping from a source URL to a target then you may want to look at the ‘URL and custom filter’:

This would allow you to create a smaller set of redirects, and pass the decision for all the variations off to some PHP code.

Thank you for the suggestion, I will dig more into that, I culled around 24k of them based on the hit rates, and will keep an eye on the 404, there are many, but some we can afford to lose.
