      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.

            Best Web-site Structure/ SEO Strategy for an online travel agency?

            Dear Experts! I need your help with pointing me in the right direction. So far I have found scattered tips around the Internet but it's hard to make a full picture with all these bits and pieces of information without a professional advice. My primary goal is to understand how I should build my online travel agency web-site’s (https://qualistay.com) structure, so that I target my keywords on correct pages and do not create a duplicate content. In my particular case I have very similar properties in similar locations in Tenerife. Many of them are located in the same villa or apartment complex, thus, it is very hard to come up with the unique description for each of them. Not speaking of amenities and pricing blocks, which are standard and almost identical (I don’t know if Google sees it as a duplicate content). From what I have read so far, it’s better to target archive pages rather than every single property. At the moment my archive pages are: all properties (includes all property types and locations), a page for each location (includes all property types). Does it make sense adding archive pages by property type in addition OR in stead of the location ones if I, for instance, target separate keywords like 'villas costa adeje' and 'apartments costa adeje'? At the moment, the title of the respective archive page "Properties to rent in costa adeje: villas, apartments" in principle targets both keywords... Does using the same keyword in a single property listing cannibalize archive page ranking it is linking back to? Or not, unless Google specifically identifies this as a duplicate content, which one can see in Google Search Console under HTML Improvements and/or archive page has more incoming links than a single property? If targeting only archive pages, how should I optimize them in such a way that they stay user-friendly. I have created (though, not yet fully optimized) descriptions for each archive page just below the main header. But I have them partially hidden (collapsible) using a JS in order to keep visitors’ focus on the properties. I know that Google does not rank hidden content high, at least at the moment, but since there is a new algorithm Mobile First coming up in the near future, they promise not to punish mobile sites for a collapsible content and will use mobile version to rate desktop one. Does this mean I should not worry about hidden content anymore or should I move the descirption to the bottom of the page and make it fully visible? Your feedback will be highly appreciated! Thank you! Dmitry

            Do I use /es/, /mx/ or /es-mx/ for my Spanish site for Mexico only

            I currently have the Spanish version of my site under myurl.com/es/ When I was at Pubcon in Vegas last year a panel reviewed my site and said the Spanish version should be in /mx/ rather than /es/ since es is for Spain only and my site is for Mexico only. Today while trying to find information on the web I found /es-mx/ as a possibility. I am changing my site and was planning to change to /mx/ but want confirmation on the correct way to do this. Does anyone have a link to Google documentation that will tell me for sure what to use here? The documentation I read led me to the /es/ but I cannot find that now.

            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?

            How does Google find /feed/ at the end of all pages on my site?

            Hi! In Google Webmaster Tools I find *.../feed/ as a 404 page in crawl errors. The problem is that none of these pages exist and they have no inbound links (except the start page). FYI, it´s a wordpress site. Example: www.mysite.com/subpage1/feed/ www.mysite.com/subpage2/feed/ www.mysite.com/subpage3/feed/ etc Does Google search for /feed/ by default or why do I keep getting these 404´s every day?

            What is the best method to block a sub-domain, e.g. staging.domain.com/ from getting indexed?

            Now that Google considers subdomains as part of the TLD I'm a little leery of testing robots.txt with something like: staging.domain.com
            User-agent: *
            Disallow: / in fear it might get the www.domain.com blocked as well. Has anyone had any success using robots.txt to block sub-domains? I know I could add a meta robots tag to the staging.domain.com pages but that would require a lot more work.

            How do I redirect index.html to the root / ?

            The site I've inherited had operated on index.html at one point, and now uses index.php for the home page, which goes to the / page. The index.html was lost in migrating server hosts. How do I redirect the index.html to the / page? I've tried different options that keep giving ending up with the same 404 error. I tried a redirect from index.html to index.php which ended in an infinite loop. Because the index.html no longer exists in the root, should I created it and then add a redirect to it? Can I avoid this by editing the .htaccess? Any help is appreciated, thanks in advance!
