How much damage in search rank will my site suffer during an upcoming cms migration?
-
Hello,
This is my first time on the seomoz forums and I hope I can get a real answer from this community of experts. I am migrating an existing site from an older cms (modx) to a newer cms (expression engine).
The domain name isn't changing and neither will the keywords and keyphrases for existing pages. What is changing, however is the url suffix. This means I am going from www.domain.com/page-name.html to www.domain.com/page-name
I can't seem to replicate the html sufffix in the new urls. Now this is the only reason why I will be setting up 301 permanent redirects from the old urls to the new ones.
My question is: Will the domain suffer a loss in page rank or a substantial decline in search engine position as a result of this migration process? How fatal will it be? When can I expect my rankings to recover?

1. Changing the information architecture could cause issues - I'm assuming that you're not doing it lightly and that you're making changes for the best. So long as you're aware of what you're doing then you should be fine.
2. Tons of new content is good- if it's good content.
3 & 4. Sounds exciting!.

Hey Mat,
Thanks for replying. I think I should add in a few details in response to your internal query observations:
- The sitemap and information architecture is changing. Will that make a difference?
- Tons of new content is being added. I assume that's a good thing. Is it?
- The old cross-linking will still remain the same - I'll make sure of it
- On-page elements will be better than on existing setup
What do you think?

Changing the extension of the page will, in itself, not damage or the rankings of pages. The main issue is, as you have identified, to ensure that the old pages 301 to the new ones. With that in place you should not notice much difference.
On paper the only difference should be a tiny (virtual imperceptible) drop in PR gained from external links pointing to the old pages. try to get the major external links updated if you can, but I wouldn't sweat that.
However... it is rarely that simple.
Watch out for changing in internal linking: If the structure changes at all (it usually does if changing CMS) that can make a big difference as internal link equity is funnelled around in different directions. Likewise be certain that the on page elements add up to a page that is at least as good as the ones it replaces.
In short: changing the extension shouldn't be an issue, however watch out for other pitfalls. Hope that helps a little.

Site redesign makes Moz Site Crawl go haywire
I work for an agency. Recently, one of our clients decided to do a complete site redesign without giving us notice. Shortly after this happened, Moz Site Crawl reported a massive spike of issues, including but not limited to 4xx errors. However, in the weeks that followed, it seemed these 4xx errors would disappear and then a large number of new ones would appear afterward, which makes me think they're phantom errors (and looking at the referring URLs, I suspect as much because I can't find the offending URLs). Is there any reason why this would happen? Like, something wrong with the sitemap or robots.txt?

Image Search
Hello Community, I have been reading and researching about image search and trying to find patterns within the results but unfortunately I could not get to a conclusion on 2 matters. Hopefully this community would have the answers I am searching for. 1) Watermarked Images (To remove or not to remove watermark from photos) I see a lot of confusion on this subject and am pretty much confused myself. Although it might be true that watermarked photos do not cause a punishment, it sure does not seem to help. At least in my industry and on a bunch of different random queries I have made, watermarked images are hard to come by on Google's images results. Usually the first results do not have any watermarks. I have read online that Google takes into account user behavior and most users prefer images with no watermark. But again, it is something "I have read online" so I don't have any proof. I would love to have further clarification and, if possible, a definite guide on how to improve my image results. 2) Multiple nested folders (Folder depth) Due to speed concerns our tech guys are using 1 image per folder and created a convoluted folder structure where the photos are actually 9 levels deep. Most of our competition and many small Wordpress blogs outrank us on Google images and on ALL INSTANCES I have checked, their photos are 3, 4 or 5 levels deep. Never inside 9 nested folders.

So... A) Should I consider removing the watermark - which is not that intrusive but is visible?
B) Should I try to simplify the folder structure for my photos? Thank you0 -
Link's that are an internal site search?
Hi hope your're all well. I sell Red, Blue, Green Widgets within each color I have many sub types, the subtypes change all the time,and a sub type has many variations in itself. I'd like to set up links that direct customers to popular searches of sub types say: widgets.com/red/blue-spots....search string... Will Google crawl these search links and see that there is good content behind it? How does Google handle links that are also a site search? Can it be bad and should I "no follow" them? Hope someone can give me some direction on these, many thanks in advance!

Site Ranking Ahead of Us - Why?
I don't want to give details, but a competitor's site ranks ahead of us by a spot or 2 for some of our major keywords, and we can't figure out why. We have more content indexed, we have better content (my opinion), we're better optimized, we have significantly better MozRank and Majestic rankings, we have more links, we have better links. They have a plain Jane Wordpress blog, and their pages don't even have 300 characters. They don't have any awesome links. There are plenty of other sites besides ours that should outrank them. When I am using the various tools at my disposal, I can see why a competitor outranks us. I'm not obsessing, but this one, I just don't understand. Has anyone had this experience?

How to handle mobile site with less pages than the main site?
We are developing a mobile version of our website that will utilize responsive design/dynamic serving. About 70% of the main website will be included in the mobile version. What (if anything) should be the redirect for pages not included in the mobile version of the site? Also - for one specific section users will be redirected from that page to the homepage, what is the redirect that should be used for this? Thanks!
