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.

Site Migration - Pagination
Hi, We are migrating our website and an issue we are facing is how to handle paginated content in our categories. Our new website will have the same structure but with different urls. Should we 301 redirect all the paginated content (if crawled by Google) to the url of the main category? To put this into an example: Old urls: www.example.com/technology/tvs (main category of TVs & also page 1) ** www.example.com/technology/tvs?v=0&page=2 ** ( page 2 of TVs) New urls: **www.example.com/soundvision/tvs **(main category of TVs & also page 1) **www.example.com/soundvision/tvs?page=2 **(page 2 of tvs) Should we redirect all of the old TV urls (also the paginated) to www.example.com/soundvision/tvs ? The is no rel next, prev tag in our site and no canonicals. Also there is a view all products page in each category, BUT it doesn't contain all the products(max. is 100 per page - yes the view all page is also paginated). The same view all products page (paginated) will exist in the new website also. I checked google search console, and Google has decided to treat as canonical page the first page www.example.com/technology/tvs . Also, all the organic traffic of our categories goes to these pages (main category page - 1st page). I would appreciate any thoughts on this.

Strange 404s in Screaming Frog
I just ran a website (Drupal) through screaming frog and the only 404s I found related to web pages which were the same as URLs already used on the website plus the company phone number so... www.company.com/[their phone number] - www.company.com/services[their phone number] - any ideas what might be causing this problem?

URL mapping for site migration
Hi all! I'm currently working on a migration for a large e-commerce site. The old one has around 2.5k urls, the new one 7.5k. I now need to sort out the redirects from one to the other. This is proving pretty tricky, as the URL structure has changed site wide. There doesn't seem to be any consistent rules either so using regex doesn't really work. By and large, the copy appears to be the same though. Does anybody know of a tool I can crawl the sites with that will export the crawled url and related copy into a spreadsheet? That way I can crawl both sites and compare the copy to match them up. Thanks!

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://moz.com/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?

Whats peoples thoughts on this? Does it work? Is it worth the effort? Im not so sure but obviously looking for ideas. Cheers

Optimize a Classifieds Site
Hi, I have a classifieds website and would like to optimize it. The issues/questions I have: A Classifieds site has, say, 500 cities. Is it better to create separate subdomains for each city (http://city_name.site.com) or subdirectory (http://site.com/city_name)? Now in each city, there will be say 50 categories. Now these 50 categories are common across all the cities. Hence, the layout and content will be the same with difference of latest ads from each city and name of the city and the urls pointing to each category in the relevant city. The site architecture of a classifieds site is highly prone to have major content which is not really a duplicate content. What is the best way to deal with this situation? I have been hit by Panda in April 2011 with traffic going down 50%. However, the traffic since then has been around same level. How to best handle the duplicate content penalty in case with site like a classifieds site. Cheers!
