Disallow: /404/ - Best Practice?
-
Hello Moz Community,
My developer has added this to my robots.txt file: Disallow: /404/
Is this considered good practice in the world of SEO? Would you do it with your clients?
I feel he has great development knowledge but isn't too well versed in SEO.
Thank you in advanced,
Nico.

This comes down to personal preference in my opinion. I think honestly it is neither here nor there. The instances that your 404 page could come up in the SERP's is more than likely pretty low and at the same time it really does not offer any useful content. So disallowing it would not really be any loss. One reason why it might be disallowed is that you have an e-commerce site that rotates products. When a product is deleted, the developer has a 301 to the 404 page, then with the robots.txt saying not to index the 404 page, the other page will drop out of search engines. If this is the case I would rethink that strategy. If you notice a lot of sites like amazon and other big sites leave the page in the index even if the product is no longer for sale. The thought is traffic is traffic, the hardest part in the whole equation is getting someone to your site, if the page is ranking, why delete it.
The only time I can think that I would specifically allow it and optimize it is if you have a cool 404 page. Some companies actually spend a bit of time on their pages and it gets them a little pop of viral traffic from social sharing sites like reddit. If you do have one that is funny or unique I would allow it and actually optimize it for a term like "funny 404 page" or something like that.

What is the best way to deal with an event calendar
I have an event calendar that has multiple repeating items into the future. They are classes that typically all have the same titles but will occasionally have different information. I don't know what is the best way to deal with them and am open to suggestions. Currently Moz anayltics is showing multiple errors (duplicate page titles, descriptions and overly dynamic urls). I'm assuming that it's showing duplicate elements way into the future. I thought of having the calendar no followed at all but the content for the classes seems valuable. Thanks,

Best Practice on 301 Redirect - Images
We have two sites that sell the same products. We have decided to retire one of the sites as we'd like to focus on one property. I know best practice is to redirect apples to apples, which in our case is easily done since the sites sold the same thing. www.SiteABC.com/ProductA can be redirected to www.SiteXYZ.com/ProductA. My question is how far does that thinking go regarding images? Each product has a main product page, of course, and then up to 6 images in some cases. Is it necessary to redirect www.SiteABC.com/ProductA-Image1.jpg to www.SiteXYZ.com/ProductA-Image1.jpg? Or can they all be redirected to just the product page?

Best URL-structure for ecommerce store?
What structure will recommend to the product pages? Lets make an example with the keyword "Luxim FZ200" With category in url:
Technical SEO | | gojesper
www.myelectronicshop.com/digital-cameras/luxim-FZ200.html With /product prefix:
www.myelectronicshop.com/product/luxim-FZ200.html Without category in url:
www.myelectronicshop.com/luxim-FZ200.html I have read in a blog post that Paddy Moogan recommend /lluxim-FZ200.html - i think i prefer this version too. But I can see that many of the bigger ecommerce stores are using a /product prefix before the product name. What is the reason for this? and what is best practice?0 -
404 Errors After Site Migration
Hello - I'm working on a website selling fashion accessories. The site just went through a site migration from Yahoo! to Big Commerce. Now we have a high level of warnings and errors from the crawl. Few are mentioning sites I never seen before on the Yahoo! platform. I also notice that the pages crawled has doubled. How can I fix or did I do something wrong with migration? I was running the website with minimal errors and now overwhelmed with errors all the error updates. If I can get some assistance on what could be wrong, I would greatly appreciate. Thanks.

Location Based Content / Googlebot
Our website has local content specialized to specific cities and states. The url structure of this content is as follows: www.root.com/seattle www.root.com/washington When a user comes to a page, we are auto-detecting their IP and sending them directly to the relevant location based page - much the way that Yelp does. Unfortunately, what appears to be occurring is that Google comes in to our site from one of its data centers such as San Jose and is being routed to the San Jose page. When a user does a search for relevant keywords, in the SERPS they are being sent to the location pages that it appears that bots are coming in from. If we turn off the auto geo, we think that Google might crawl our site better, but users would then be show less relevant content on landing. What's the win/win situation here? Also - we also appear to have some odd location/destination pages ranking high in the SERPS. In other words, locations that don't appear to be from one of Google's data center. No idea why this might be happening. Suggestions?

Cloaking? Best Practices Crawling Content Behind Login Box
Hi- I'm helping out a client, who publishes sale information (fashion sales etc.) In order for the client to view the sale details (date, percentage off etc.) they need to register for the site. If I allow google bot to crawl the content, (identify the user agent) but serve up a registration light box to anyone who isn't google would this be considered cloaking? Does anyone know what the best practice for this is? Any help would be greatly appreciated. Thank you, Nopadon

Merging several sites into one - best practice
I had 2 sites on the web (www.physicseditor.de, www.texutrepacker.com) and decided to move them all under one single domain (www.codeandweb.com) Both sites were ranking very good for several keywords. I not redirected the most important pages from the old domains with a 301 redirect to the new subpages (www.texturepacker.com => www.codeandweb.com/texturepacker) Google still delivers the old domains but the redirect take people directly to the new content. I've already submitted the new site map to google webmaster tools. Pages are already in the index but do not really show up in the search results. How long does it take until google accepts the new domain and delivers the new content in the search results? Was it ok what I did? Or is there some room for improvement? SeoMoz will of course not find any information about the new page since it is not yet directly linked in google. But I can't get ranking information for the "old" pages since SeoMoz tells me that it can't crawl the old domains....

What is best practice for redirecting "secondary" domain names?
For sites with multiple top-level domains that have been secured for a business or organization, I'm curious as to what is considered best practice for setting up 301 redirects for secondary domains. Is it best to do the 301 redirects at the registrar level, or the hosting level? So that .net, .biz, or other secondary domains funnel visitors to the correct primary/main domain name. I'm looking for the "best practice" answer and want to avoid duplicate content problems, or penalties from the search engines. I'm not trying to game the system with dozens of domain names, simply the handful of domains that are important to the client. I've seen some registrars recommend hosting secondary domains, and doing redirects from the hosting level (and they use meta refresh for "domain forwarding," which I want to avoid). It seems rather wasteful to set up hosting for a secondary domain and then 301 each URL.
