We have changed 5 pages on our Zen Cart Software and need to ENSURE that each old page has a 301 re-direct to the new page to avoid Google caching duplicates.
We will give the successfull bidder the 5 old page urls and the 5 new page urls to direct them to. Once done, we will ask our SEO experts to check that they are indeed setup properly and payment will follow straight away.
All code must be W3C complaint and adhere to Googles guidelines on 301 re-directs - [url removed, login to view]
All code must be compatible with Zen Cart's architecture and not cause any adverse effects to it.
