Transfer link juice from old to new site

[Ideas-Money-Art]

Hi seomozzers,

The design team is building a new website for one of our clients. My role is to make sure all the link juice is kept.

My first question is, should I just make 301s or is there another technique to preserve all the link juice from the old to new site that I should be focusing on?

Second Question is that ok to transfer link juice using dev urls like www.dev2.example.com (new site) or 182.3456.2333? or should I wait the creation of real urls to do link juice transfer?

Thank you

What Justin said! And yes, 301's pass 95-99% of all link juice.

Hi Taysir

i would definitely not recommend transferring the link juice until you have the real urls set up, as this may detract from the links when they go live.

also you could use what is known as a canonical link to transfer this link juice.

you can find out more about using these links here, also helps with duplicate content on your site:-

hope this helps
