A Client Changed the Link Structure for Their Site... Not Just Once, but Twice
-
I have a client who's experiencing a number of crawl errors, which I've gotten down fo 9,000 from 18,000. One of the challenges they experience is that they've modified their URL structure a couple times.
First it was: site.com/year/month/day/post-name
Then it was: site.com/category/post-name
Now it's: site.com/post-nameI'm not sure of the time elapsed between these changes, but enough time has passed that the URLs for the previous two URL structures have been indexed and spit out 404s now.
What's the best/clean way to address this issue?I'm not going to create 9k redirect rules obviously, but there's got to be a way to address this issue and resolve it moving forward.

That looks like a very useful plugin Keri

Look for the "Redirection" plugin for Wordpress, that can help you make redirects easily. It's also an easy way to let you see what's a 404 on your site, and make redirects from the page listing the 404s.

Sure, here's the mod_rewrite guide straight from the horse's mouth
http://httpd.apache.org/docs/2.0/misc/rewriteguide.htmlHere's a nice beginner's guide:

Wow guys! Thanks for the responses. You've given me a couple things to think about.
The suggestions from Thomas and GYMSN might be the way I choose to plod ahead. Though, the rewrite rule seems like an interesting play. I have no idea what either of those lines mean. Heh. Is there a reference you could recommend, Woj, that might shed more light on rewrite rules?
A couple technical pieces to throw out there:
1. It's a WordPress site, so they don't have "folders," per se.
2. They run on linux, with an apache web server

Ryan is absolutely spot on.. you can create some redirection rules in the .htaccess (assuming the site's on apache)
something along the lines of..
RewriteRule ^([0-9]{4})/([0-9]{2})/([0-9]{2})/(.*)$ /$4 [R=301,NC,L]
RewriteRule ^category/(.*)$ /$1 [R=301,NC,L]
(of course if totally depends on your site structure & I'd test these on a staging server if possible)
-
Thomas did what we did and it worked fine. We lost a ton of Yahoo rankings for significant keywords though. I now personally never change /url/keywords unless I don't care about the Yahoo traffic (or there is none). Google has no problem with it.
-
You could do this with one or two clever regex commands, the composition of which I can't think of cos its too close to quitting time on Friday. But yeah you don't need 9000 rules.
-
Have you tried creating a redirect rule for each of the folders? From you example above the "post-name" has remained consistent. Therefore if you create a redirect from each folder then you should see a proper resolution with just appending the "post-name"

301ing one site's links to another
Hi, I have one site with a well-established link profile, but no actual reason to exist (site A). I have another site that could use a better link profile (site B). In your experience, would 301 forwarding all of site A's pages to site B do anything positive for the link profile/organic search of the site B? Site A is about boating at a specific lake. Site B is about travel destinations across the U.S. Thanks! Best... Michael

Best possible linking on site with 100K indexed pages
Hello All, First of all I would like to thank everybody here for sharing such great knowledge with such amazing and heartfelt passion.It really is good to see. Thank you. My story / question: I recently sold a site with more than 100k pages indexed in Google. I was allowed to keep links on the site.These links being actual anchor text links on both the home page as well on the 100k news articles. On top of that, my site syndicates its rss feed (Just links and titles, no content) to this page. However, the new owner made a mess, and now the site could possibly be seen as bad linking to my site. Google tells me within webmasters that this particular site gives me more than 400K backlinks. I have NEVER received one single notice from Google that I have bad links. That first. But, I was worried that this page could have been the reason why MY site tanked as bad as it did. It's the only source linking so massive to me. Just a few days ago, I got in contact with the new site owner. And he has taken my offer to help him 'better' his site. Although getting the site up to date for him is my main purpose, since I am there, I will also put effort in to optimizing the links back to my site. My question: What would be the best to do for my 'most SEO gain' out of this? The site is a news paper type of site, catering for news within the exact niche my site is trying to rank. Difference being, his is a news site, mine is not. It is commercial. Once I fix his site, there will be regular news updates all within the niche we both are in. Regularly as in several times per day. It's news. In the niche. Should I leave my rss feed in the side bars of all the content? Should I leave an achor text link on the sidebar (on all news etc.) If so: there can be just one keyword... 407K pages linking with just 1 kw?? Should I keep it to just one link on the home page? I would love to hear what you guys think. (My domain is from 2001. Like a quality wine. However, still tanked like a submarine.) ALL SEO reports I got here are now Grade A. The site is finally fully optimized. Truly nice to have that confirmation. Now I hope someone will be able to tell me what is best to do, in order to get the most SEO gain out of this for my site. Thank you.

What SEO tactics are effective for optimising a site where content is changing very frequently (for example an online newspaper)?
I have always worked with sites where content has a reasonably long life-span but need to now consider SEO for a site where content is changing very rapidly. I have read that Google will re-spider your content more frequently if it finds that it is changing frequently but are there effective ways to let the search engines know as new articles are published? Also, if content is removed within only a day or two of being published, can this have a negative impact on SEO?

Link Acquisition - link building
When using Site Explorer to find out my competiters links so I can do some link aquisition SEO do I look for the "inbound" links or or "linking domains"? Also, what filters should I choose? I want to make a spreadsheet as Rand suggested in his video and start to prioritize my link building.

Best way to find broken links on a large site?
I've tried using Xenu, but this is a bit time consuming because it only tells you if the link sin't found & doesn't tell you which pages link to the 404'd page. Webmaster tools seems a bit dated & unreliable. Several of the links it lists as broken aren't. Does anyone have any other suggestions for compiling a list of broken links on a large site>

How to remove bad link to your site?
Hello, Our website www.footballshirtblog.co.uk recently suffered a major Google penalty, wiping out 6 months of hard work. We went from getting 6000-10000 hits a day to absolutely nothing from Google. We have been baffled by the penalty as we couldn't think of anything we've done wrong. After some analysis of Open Site Explorer, it seems I may have found the answer. There is a ton of bad links pointing to us. A few example domains are: ru.gg/ gogopzh.com/ 0575bbs.com/ This is nothing to do with us and so I can only assume some competitor has done this. As we were only about 4-5 months old, I guess Google has punished us. What do we do now? This is not a situation I have experienced before and would really appreciate your expert advice.

Multiple sites linking back with pornographic anchor text
I discovered a while ago that we had quite a number of links pointing back to one of our customer's websites. The anchor text of these links contain porn that is extremely bad. These links are originating from forums that seems to link between themselves and then throw my customers web address in there at the same time. Any thoughts on this? I'm seriously worried that this may negatively affect the site.
