Bad site migration - what to do!
-
Hi Mozzers - I'm just looking at a site which has been damaged by a very poor site migration.
Basically, the old URLs were 301'd to a page on the new website (not a 404) telling everyone the page no longer existed.
They did not 301 old pages to equivalent new pages. So I just checked Google WMT and saw 1,000 crawl errors - basically the old URLs.
This migration was done back in February, since when traffic to the website has never recovered. Should I fix this now? Is it worth implementing the correct 301s now, after such a timelapse?

Thanks for advice Paul - I've edited pages with poor backlink profiles out of redirect and 301'd the rest to relevant pages within the new website, and traffic has spiked up a bit. There were some very powerful links (national newspapers, etc) the new site was missing out on.

Gonna have to disagree with Rob a bit here on one point. Definitely agree that it's still worth implementing the correct 301 redirects. However, by only doing it for page already getting traffic or having links, you're going to miss out on potentially a substantial amount of future traffic, especially long-tail (which is very valuable).
There can be many pages which Google has indexes and which can return for search results even though the pages don't have incoming links. To my mind, it would be a shame to throw away that traffic. It is possible to collect a list of all the pages of your site Google has in it's index, but its often easier to just correctly redirect them all. Often groups of pages can be redirected using a single redirect to reduce the amount of work involved.
At the very least, make certain you have implemented an effective 404 page, and also ensure you have included your Google Analytics tracking code on the 404 page. Then you can use a combination of Analytics and Webmaster Tools to catch any incoming 404s and get them redirected immediately.
Does that make sense?

Thanks SErOb - good advice!

At this point, I'd only adjust 301's for the pages actual users are trying to access and pages with good backlinks.
Google will always have a record of the old pages in WMT, don't fret over that.

301 redirecting a site that currently links to the target site
I have a personal blog that has a good amount of back links pointing at it from high quality relevant authoritative sites in my niche. I also run a company in the same niche. I link to a page on the company site from the personal blog article that has bunch of relevant links pointing at it (as it's highly relevant to the content on the personal blog). Overview: Relevant personal blog post has a bunch of relevant external links pointing at it (completely organic). Relevant personal blog post then links (externally) to relevant company site page and is helping that page rank. Question: If I do the work to 301 the personal blog to the company site, and then link internally from the blog page to the other relevant company page, will this kill that back link or will the internal link help as much as the current external link does currently? **For clarity: ** External sites => External blog => External link to company page VS External sites => External blog 301 => Blog page (now on company blog) => Internal link to target page I would love to hear from anyone that has performed this in the past 🙂

If UGC on my site also exists elsewhere, is that bad? How should I properly handle it?
I work for a reviews site, and some of the reviews that get published on our website also get published on other reviews websites. It's exact duplicate content -- all user generated. The reviews themselves are all no-indexed; followed, and the pages where they live are only manually indexed if the reviews aren't duplicate. We leave all pages with reviews that live elsewhere on the web nofollowed. Is this how we should properly handle it? Or would it be OK to follow these pages regardless of the fact that technically, there's exact duplicate UGC elsewhere?

Huge e-commerce site migration - what to do with product pages?
My very large e-commerce client is about to undergo a site migration in which every product page URL will be changing. I am already planning my 301 redirect process for the top ~1,000 pages on the site (categories, products, and more) but this will not account for the more than 1,000 products on the site. The client specified that they don't want to implement much more than 1,000 redirects so as to avoid impacting site performance. What is the best way to handle these pages without causing hundreds of 404 errors on site migration day? Thanks!

New site now links disappearing in Open Site Explorer and GWT
We launched a new site at the beginning of December 2012 and carefully 301'd all URLs from the old site to the new (custom CMS on old site wordpress on new). Our rankings have slipped quite badly but the most worrying thing is that we used to have about 1200 backlinks according to GWT/OSE before the new site launched and now we're down to about 30. Can anyone help shed some light on this please? The site is www.littleoneslondon.co.uk A few things that might help: 1. We were getting a lot of links through our job feeds (it's a nanny recruitment site) on indeed and trovitt, for some reason no new ones from these have appeared in site explorer and all the old jobs are gone completely. 2. We had 1000s of not found errors in google webmaster tools and once these were redirected and marked as fixed this is when the links disappeared. 3. We are getting quite a few 504 errors on the site due to an old proxy redirect (/blog was hosted on a different server on the old site and has not been removed yet), this will be fixed tomorrow but could this be a factor? 4. The developer seems to have redirected all the links through wordpress directly some how (I don't see any redirect plugins but there are lots of pages called 'redirect'). There are no references in the htaccess file for any redirects other than from the /blog folder that the wordpress instance sits in. Sorry for the long post, I hope I've given any details you'd need and I really appreciate any help anyone can give. Thanks, Karl

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.

What on-page/site optimization techniques can I utilize to improve this site (http://www.paradisus.com/)?
I use a Search Engine Spider Simulator to analyze the homepage and I think my client is using black hat tactics such as cloaking. Am I right? Any recommendations on to improve the top navigation under Resorts pull down. Each of the 6 resorts listed are all part of the Paradisus brand, but each resort has their own sub domain.

Site: on Google
Hello, people. I have a quick question regarding search in Google. I use search operator [site:url] to see indexing stauts of my site. Today, I was checking indexing status and I found that Google shows different numbers of indexed pages depends on search setting. 1. At default setting (set as 10 search result shows) > I get about 150 pages indexed by Google. 2. I set 100 results shows per page and tried again. > I get about 52 pages indexed by Google. Of course I used same page URL. I really want to know which data is accurate. Please help people!!

Can your site be penalised by backlinks?
Hi, I just wanted to get some clarification on whether Google would penalize your site if you had many links coming from a questionable site. We've been struggling with rankings for years even though we have one of the oldest sites in the industry with a good link profile and the site is well optimized. I was looking through webmaster tools and noticed that one website links to us over 100,000 times, all to the home page. The site is www.vietnamfuntravel.com. When I looked at the site it seems that they operate a massive links exchange, I'm not sure what the history is and why they link to us so much though. Is there any chance that this could impact us negatively? if it is then what would be the best way to deal with the situation? I could ask them to take the links down but can't guarantee they would do it quickly (if at all). Would blocking their domain from our htaccess file have the desired effect?
