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.

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 .

Google cache is showing my UK homepage site instead of the US homepage and ranking the UK site in US
Hi There, When I check the cache of the US website (www.us.allsaints.com) Google returns the UK website. This is also reflected in the US Google Search Results when the UK site ranks for our brand name instead of the US site. The homepage has hreflang tags only on the homepage and the domains have been pointed correctly to the right territories via Google Webmaster Console.This has happened before in 26th July 2015 and was wondering if any had any idea why this is happening or if any one has experienced the same issueFDGjldR

Multilingual Site and 301 redirection
Hey there awesome people of Moz I have this site that has many languages in it. The main language is English and my developer did the following www.example.com ( is the main site ) which redirects with a 301 to www.example.com/en if your geo location is supported by our languages then you will automatically be redirected to whatever language you have in your country but does the first language with is english have to 301 redirect to www.example.com/en ? I thought that the right way is to just leave /en at the root file. Thanks in advance

What's the deal with significantLinks?
http://schema.org/significantLink Schema.org has a definition for "non-navigation links that are clicked on the most." Presumably this means something like the big green buttons on Moz's homepage. But does anyone know how they affect anything? In http://a-moz.groupbuyseo.org/blog/schemaorg-a-new-approach-to-structured-data-for-seo#comment-142936, Jeremy Nelson says " It's quite possible that significant links will pass anchor text as well if a previous link to the page was set in navigation, effictively making obselete the first-link-counts rule, and I am interested in putting that to test." This is a pretty obscure comment but it's one of the only results I could find on the subject. Is this BS? I can't even make out what all of it is saying. So what's the deal with significantLinks and how can we use them to SEO?

So What On My Site Is Breaking The Google Guidelines?
I have a site that I'm trying to rank for the Keyword "Jigsaw Puzzles" I was originally ranked around #60 or something around there and then all of a sudden my site stopped ranking for that keyword. (My other keyword rankings stayed) Contacted Google via the site reconsideration and got the general response... So I went through and deleted as many links as I could find that I thought Google may not have liked... heck, I even removed links that I don't think I should have JUST so I could have this fixed. I responded with a list of all links I removed and also any links that I've tried to remove, but couldn't for whatever reasons. They are STILL saying my website is breaking the Google guidelines... mainly around links. Can anyone take a peek at my site and see if there's anything on the site that may be breaking the guidelines? (because I can't) Website in question: http://www.yourjigsawpuzzles.co.uk UPDATE: Just to let everyone know that after multiple reconsideration requests, this penalty has been removed. They stated it was a manual penalty. I tried removing numerous different types of links but they kept saying no, it's still breaking rules. It wasn't until I removed some website directory links that they removed this manual penalty. Thought it would be interesting for some of you guys.
