          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.

                  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.

                  Using the same image across the site?

                  Hi just wondering i'm using the same image across 20 pages which are optimized for SEO purposes. I was wondering is there issues with this from SEO standpoint? Will Google devalue the page because the same image is being used? Cheers.

                  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

                  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?

                  Moving to a new site while keeping old site live

                  For reasons I won't get into here, I need to move most of my site to a new domain (DOMAIN B) while keeping every single current detail on the old domain (DOMAIN A) as it is. Meaning, there will be 2 live websites that have mostly the same content, but I want the content to appear to search engines as though it now belongs to DOMAIN B. Weird situation. I know. I've run around in circles trying to figure out the best course of action. What do you think is the best way of going about this? Do I simply point DOMAIN A's canonical tags to the copied content on DOMAIN B and call it good? Should I ask sites that link to DOMAIN A to change their links to DOMAIN B, or start fresh and cut my losses? Should I still file a change of address with GWT, even though I'm not going to 301 redirect anything?

                  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.

                  Multiple sites in the same niche

                  Hi All A question regarding multiple sites in the same niche... If I have say 10 sites all targetting the same niche yet all on different C-class IPs with different hosts, registrars, whois data and ages can I use the same template, or will Google discern a pattern? Basically I have developed a WordPress template which I want to use on the sites albeit with different logos / brand colours. NB/ All of the 10 sites will have unique, original content and they will NOT be interlinked

                  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!
