Dealing with 404s during site migration
-
Hi everyone - What is the best way to deal with 404s on an old site when you're migrating to a new website? Thanks, Luke
-
thanks Moosa - it does

-
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.

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

Sitemaps during a migration - which is the best way of dealing with them?
Many SEOs I know simply upload the new sitemap once the new site is launched - some keep the old site's URLs on the new sitemap (for a while) to facilitate the migration - others upload both the old and the new website together, to support the migration. Which is the best way to proceed? Thanks, Luke

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:
Intermediate & Advanced SEO | | ArchMedia
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?0 -
Wrong titles in site links
Hello fellow marketers, I have found this weird thing with our website in the organic results. The sitelinks in the SERP shows wrong written text. As in grammatically incorrect text. My question is where does Google get the text from? It is not the page title as we can see it. kKsFv0X.png

Merging Sites: Will redirecting the old homepage to an internal page on the new site cause issues?
I've ended up with two sites which have similar content (but not duplicate) and target similar keywords, rather than trying to maintain two sites I would like to merge the sites together. The old site is more of a traditional niche site and targets a particular set of keywords on its homepage, the new site is more of an authority site with a magazine type homepage and targets the same set of keywords from an internal page. My question is: Should I redirect the old site's homepage to the relevant internal page on the new website...
Intermediate & Advanced SEO | | lara_dar
...or should I redirect the old site's homepage to the new site's homepage? (the old site's homepage backlinks are a mixture of partial match keyword anchor text, naked URLs and branded anchor text) I am in two minds (a & b!) (a) Redirecting to the internal page would be great for ranking as there are some decent backlinks and the content is similar (b) But usually when you do a 301 redirect the homepage usually directs to the new homepage and some of the old site's links are related to the domain rather than the keyword (e.g. http://www.site.com) and some people will be looking for the site's homepage. What do you think? Your help is much appreciated (and hope this makes sense...!)0 -
Noindex a meta refresh site
I have a client's site that is a vanity URL, i.e. www.example.com, that is setup as a meta refresh to the client's flagship site: www22.example.com, however we have been seeing Google include the Vanity URL in the index, in some cases ahead of the flagship site. What we'd like to do is to de-index that vanity URL. We have included a no-index meta tag to the vanity URL, however we noticed within 24 hours, actually less, the flagship site also went away as well. When we removed the noindex, both vanity and flagship sites came back. We noticed in Google Webmaster that the flagship site's robots.txt file was corrupt and was also in need of fixing, and we are in process of fixing that - Question: Is there a way to noindex vanity URL and NOT flagship site? Was it due to meta refresh redirect that the noindex moved out the flagship as well? Was it maybe due to my conducting a google fetch and then submitting the flagship home page that the site reappeared? The robots.txt is still not corrected, so we don't believe that's tied in here. To add to the additional complexity, the client is UNABLE to employ a 301 redirect, which was what I recommended initially. Anyone have any thoughts at all, MUCH appreciated!

URL Structure for Directory Site
We have a directory that we're building and we're not sure if we should try to make each page an extension of the root domain or utilize sub-directories as users narrow down their selection. What is the best practice here for maximizing your SERP authority? Choice #1 - Hyphenated Architecture (no sub-folders): State Page /state/ City Page /city-state/ Business Page /business-city-state/
Intermediate & Advanced SEO | | knowyourbank
4) Location Page /locationname-city-state/ or.... Choice #2 - Using sub-folders on drill down: State Page /state/ City Page /state/city Business Page /state/city/business/
4) Location Page /locationname-city-state/ Again, just to clarify, I need help in determining what the best methodology is for achieving the greatest SEO benefits. Just by looking it would seem that choice #1 would work better because the URL's are very clear and SEF. But, at the same time it may be less intuitive for search. I'm not sure. What do you think?0
