Ecommerce catalog update: 301 redirects?
-
Hello mozers,
We run an ecommerce store and are planning a massive catalog update this month. Essentially, 100% of our product listings will be deleted, and an all new catalog will be uploaded. The new catalog contains mostly new products, however there are some products that already existing in the old catalog as well.
The new catalog has a bunch of improvements to the product pages, included optimized meta titles and descriptions, multiple language, optimized URLs and more.
My question is the following:
When we delete the existing catalog, all indexed URLs will return 404 errors. Setting up 301 redirects from old to new products (for products which existing previously) is not feasible given the number of products. Also, many products are simply being remove entirely.
So should we go ahead and delete all products, upload the new catalog, update the sitemap, resubmit it for crawling, and live with a bunch of 404 errors until these URLs get dropped from Google?
The alternative I see is setting 301 redirects to the home page, but I am not sure this would be correct use of 301 redirects.
Thanks for your input.

Thanks for the info.
In my books a 301 redirect is for a direct replacement of an old webpage for a new one. I knew a bunch of 404 errors would be problematic, but I was also worried setting up 301 redirects to the home page (which is not a replacement for the product page being removed) would not agree with best practices.
Also good point regarding existing incoming links pointing to the pages being removed.
I think what we'll do is export URLs from the Google index, and either set a 301 redirect to the new product page (if it exists) or if not we'll 301 redirect to that product's category page.

I don't fully agree with the answer above - having 404's is not a direct cause for demoting. Check https://googlewebmastercentral.blogspot.be/2011/05/do-404s-hurt-my-site.html . Another interesting video on expired e-commerce products is here: http://searchengineland.com/googles-matt-cutts-seo-advice-unavailable-e-commerce-products-186882. Redirecting to the homepage (or any other non related page) is certainly not a good thing - this would be considered a soft 404.
It is however best practice to redirect products that remain in the catalog to the newer versions of the page. Even for those that don't remain in catalog you might consider to redirect them to a closely related new product. You indicate that given the number of products this would be not feasible. Are there no common patterns in the url to redirect these pages in bulk? Is it possible to put the redirect in the page header?
Redirects (properly implemented = going to the corresponding content) are both good for users & Google. If you don't redirect it will take some time before the new products are indexed and replacing the old ones in the ranking - which will almost certainly lead to rank loss: the 404 results will quickly disappear from the results and it will take a lot longer for the new ones to take their positions, it they manage to get back to these positions at all.
If you happen to have links point to these old product pages - you will loose these as well if they go to a 404.
In case that redirects is indeed not a valid option - make sure that you have a custom 404 pages so that user can easily find what their looking for. It might reduce the damage a bit.
If it was my site - I would try to find a solution to implement 301's.

You should definitely not let those URLs die. Having a ton of 404 errors is a sure fire way to have Google demote your site for poor quality. I recommend selecting your top 100 or so products, based on Google Analytics traffic numbers and importance to your business, and apply one-to-one 301 redirects for those. The rest of the old products can be redirected to the homepage, or maybe the main store page.

Ecommerce Google Bias?
Does Google bias the type of content which ranks? HI Guys, If i wanted to create a nice blog post around a topic like: black dresses or yoga pants. If you view google.com or google.com.au results all the top ranking URLs are e-commerce pages which list the products. There is very rarely - blog content e.g. top black dresses to wear... or 7 of the hottest yoga pants on the market. The search intent is about the same i.e. someone looking for black dresses would be interested in that blog post. So in my conclusion Google has some form of bias in delivering ecommerce sites above blog/skyscrapper form of content. Thoughts? Cheers.

301 Redirects - 4 sites into 1
Hey all, I have an SEO conundrum that seems to have no right or wrong answer. If you have 2 minutes I’d love to hear your opinion. The Situation
Intermediate & Advanced SEO | | PamelaH88
Our client has 4 ecommerce sites (Sites A, B, C & D) all selling the same products.
He wishes to to merge all 4 sites into a single site (Site A) Options
In order to maintain maximum SEO authority do we: A - Choose a single site (B, C, or D) with the most SEO authority/juice/power and 301 re-direct it into Site A
Or
B – 301 re-direct all 3 sites (B, C & D) into Site A Our experience says that 301’ing from a single site works well, but from multiple sites feels spammy and risky. Really keen too hear your thoughts.1 -

A 302 Redirect Question | Events Page Updates
Hello Moz World, I have a client that has a TON, like close to a thousand pages that have a 302 redirect set up. After further investigation, I found that every month they update their events page & Demo Request page, and the old events pages still exist but, get a 302 redirect to the updated page. From what I gather, this is a default mechanism set up by the hosting provider. My questions; is this an example of when to use a Rel=canonical? Also, is there a method for integrating this without having to go into every page and integrate the code snippet? And Lastly, How should I go about ensuring this doesn't happen in the future? Thanks ahead of time, you guys rock! B/R Will H.

Ranking EMD to 301 for branding is it better to leave it as or 301 it?
We have a client about to enroll with us for SEO. The client has about 50 EMD sites, out of which 9 are ranking. An EMD has [Exact] match anchoring naturally, the sites in question are all EMDs the link profiles show it. The client wants to 301 the EMDs to a brand page.. We would want to 301, 9 EMD sites to the new site. Here is the thing, if the site domain has an exact match to the anchor text profile, when we 301 the page to www.brand.com/EMD will the link profile matter? One of the EMDs is on page one spot 2 if we do this change, will Google look at the new brand page (www.brand.com/EMD) as an unnatural link profile?

Redirect help
I work for a company that has a domain that is something like www.neat-stuff.com but most people just use www.neatstuff.com without the dash. The redirect for the homepage works fine. We recently launched a new site and if you use www.neat-stuff.com/category it redirects from the old site to the new site just fine. However if you use www.neatstuff.com/category it does not properly redirect to www.neat-stuff.com/category. How do I fix that?

Setting up of 301 redirects
Good morning all, As part of the analysis of our website, we have realised that we are diluting our keyword strength in a particular area by having multiple zones all targeting the same keyword. We have decided to combine these zones into one, and set up 301 redirects so that the remaining zone gets the benefit of the other zones' link juice. When setting up a 301 redirect from zone "X" to zone "Y" say, do I need to keep all of the content in zone X, or should I remove all content before the redirect is set up? Does zone Y still get the benefit of zone X's link juice if the content is removed? Many thanks Guy

301 Redirect - How Long Until Recovery?
How long after one moves a page and sets up the 301s should the site take to regain its previous rankings? Context: i've ported a site to a new framework. Along the way, several high ranked pages needed to have new URLs setup, as well as the site moved from www.domain.com to simply domain.com. About 1 week after the change, the site's traffic went down 70% and has been there for about another 2 weeks. I suppose it could be something about the new framework that is causing problems though according to SEOMoz tools, the new framework is checking out pretty well. I assume the problem is reconciling all those old www inbound links with the new non-www location. It is all 301'd however ... so it should be working, but is not. So my questions are: 1. How long should it take Google to reconcile these changes and put us back to original SERP positions 2. is there something inherently problematic with switching from www to non-www?
