          Thanks - useful feedback - Do you need to forward existing 301s as well? 301s on the site you're moving from? Or might that create complications?

            I agree with Russ! If you have a 404 page see if you have exact page on your new website (or atleast nearer to exact) if yes, redirect! If you are in to ecommerce industry and you really don’t think that 404 page have any other alternate, in that case try redirecting it to 404 pages!

            Make sure the page is customized, provide value to users and allow them to continue their journey on the website.

            Hope this helps!

              If you can, find an exact or close-to-exact replacement on your new site and 301 redirect. You might want to go through analytics to find any trafficked pages and make sure you have them 301 redirected as well. In some cases, you might need to 404 pages, but make sure the 404 pages are useful to help your users find the best content on the new site.

                  How do I treat URLs with bookmarks when migrating a site?

                  I'm migrating an old website into a new one, and have several pages that have bookmarks on them.  Do I need to redirect those? or how should they be treated? For example, both https://www.tnscanada.ca/our-expertise.html and https://www.tnscanada.ca/our-expertise.html#auto resolve .

                  Breaking up a site into multiple sites

                  Hi, I am working on plan to divide up mid-number DA website into multiple sites. So the current site's content will be divided up among these new sites. We can't share anything going forward because each site will be independent. The current homepage will change to just link out to the new sites and have minimal content. I am thinking the websites will take a hit in rankings but I don't know how much and how long the drop will last.  I know if you redirect an entire domain to a new domain the impact is negligible but in this case I'm only redirecting parts of a site to a new domain. Say we rank #1 for "blue widget" on the current site. That page is going to be redirected to new site and new domain. How much of a drop can we expect? How hard will it be to rank for other new keywords say "purple widget" that we don't have now? How much link juice can i expect to pass from current website to new websites? Thank you in advance.

                  Should I migrate .co.uk to .com?

                  I have previously searched the forum and could not find a definitive answer on this subject so would appreciate any guidance. I have just joined a new company, we have a .co.uk site which gets lots of traffic. We have a .com site which is targeting USA and .com/de/ targeting Germany. 'hreflang' is configured on the .com (between the USA and German sites) but not on .co.uk. This means that in the eyes of search engines (and Moz Pro) the 2 domains are competitors (and the .co.uk has much more presence than the .com in the USA). I know how to fix this and I am in the process of doing so. My question is whether it would make sense to migrate the .co.uk site to .com As previously mentioned the .co.uk site already does very well both in the UK and around the world (as our product is well known in our niche). As .co.uk can only primarily be targeted to UK would our global reach increase enough to justify migrating it to .com? We have dealers/distributors in maybe 30 countries and are continuing to expand, we will at point point add additional languages so my suggestion is that we migrate now as the authority of the .co.uk will help the emerging markets as well as increase our visibility in markets that are not currently primary targets. We are also in the process of hiring new staff specifically to focus on Content Marketing. So again this suggests having the 1 domain will make sense in the long run (as any value gained from content marketing success will be seen by all country/language focussed sites). I am also planning to rebuild the sites in the next few months as the current ones are not fit for purpose so the migration would coincide with this (I know this is not ideal). Apologies for the lengthy question, I hope the additional background information will help in providing some feedback to help me make the decision. David

                  Should I redirect images when I migrate my site

                  We are about to migrate a large website with a fair few images (20,000). At the moment we include images in the sitemap.xml so they are indexed by Google and drive traffic (not sure how I can find out how much though). Current image slugs are like:
                  http://website.com/assets/images/a2/65680/thumbnails/638x425-crop.jpg?1402460458 Like on the old site, images on the new website will also have unreadable cache slugs, like:
                  http://website.com/site_media/media/cache/ce/7a/ce7aeffb1e5bdfc8d4288885c52de8e3.jpg All content pages on the new site will have the same slugs as on the old site. Should I go through the trouble of redirecting all these images?

                  Why does a site have no domain authority?

                  A website was built and launched eight months ago, and their domain authority is 1.  When a site has been live for a while and has such a low DA, what's causing it?

                  How To Best Close An eCommerce Site?

                  We're closing down one of our eCommerce sites. What is the best approach to do this? The site has a modest link profile (a young site). It does have a run of site link to the parent site. It also has a couple hundred email subscribers and established accounts. Is there a gradual way to do this? How do I treat the subscribers and account holders? The impact won't be great, but I want to minimize collateral damage as much as possible. Thanks.
