      We are building URLs dynamically with apache rewrite.
      When we detect that an URL is matching some valid patterns, we serve a script which then may detect that the combination of parameters in the URL does not exist. If this happens we produce a 301 redirect to another URL which serves a 404 error page,

      So my doubt is the following: Do I have to worry about not serving directly an 404, but redirecting (301) to a 404 page? Will this lead to the erroneous original URL staying longer in the google index than if I would serve directly a 404?

      Some context. It is a site with about 200.000 web pages and we have currently 90.000 404 errors reported in webmaster tools (even though only 600 detected last month).

          I suspect you may be right.

          How long ago did they appear?

          Are they starting to go gradually down or up?

            thanks a lot SilverDoor.

            The huge number of errors, were caused by a problem with the internal site architecture several months ago which got thousdands of pages in the index that should not exist (and also have no other related relevanted pages). This architecture is fixed now. Still for some reason mobile crawler of webmaster tools is returning now suddenly lots of 404 for mobile view, which I suspect are coming from old 404 in google cache.

              Hi,

              You should never redirect to a 404 page.

              Search Engines are going to see this as an error and may even think you are trying to manipulate users around your site.

              I would redirect the pages to a relevant page on your site.

              With regards to the huge number of errors now appearing, I need some more details to answer the question:

              • How many 404's would you expect there to be (give an estimate)?
              • How many 301 redirects do you think would have been implemented with the script?
              • Have you recently changed anything else with the HTTP Status Codes?

              SilverDoor

                Using H3 before or instead of an H2...

                My designer and I have been having an argument: we have a blog with short, 400 words posts. They have an H1 with nice keywords and a catchy title, and then a few subheadings. I don't like making the subheadings H2, because the font looks way too large in Wordpress, so my designer wants to make them all H4s, so the font looks to be a nicer size. Here's my problem with that and why I usually just bold the subheadings: Is it really bad to put a bunch of H4s right under an H1, with not H2's or 3's to separate? I'm reading different arguments on the internet about this and gladly welcome more debate and/or case studies. Thank you!

                Website Redesign, 301 Redirects, and Link Juice

                I want to change my client’s ecommerce site to Shopify. The only problem is that Shopify doesn’t let you customize domains. I plan to: keep each page’s content exactly the same keep the same domain name 301 redirect all of the pages to their new url The ONLY thing that will change is each page’s url. Again, each page will have the exact same content. The only source of traffic to this site is via Google organic search and sales depend on the traffic. There are about 10 pages that have excellent link juice, 20 pages that have medium link juice, and the rest is small link juice. Many of our links that have significant link juice are on message boards written by people that like our product. I plan to change these urls and 301 redirect them to their new urls. I’ve read tons of pages online about this topic. Some people that say it won’t effect link juice at all, some say it will might effect link juice temporarily, and others are uncertain. Most answers tend to be “You should be good. You might lose some traffic temporarily. You might want to switch some of your urls to the new structure to see how it affects it first.” Here’s my question: 1) Has anyone ever done changed a url structure for an existing website with link juice? What were your results and do you have a definitive answer on the topic? 2) How much link juice (if any) will be lost if I keep all of the exact content the same but only change each page’s url? 3) If link juice is temporarily lost and then regained, how long will it be temporarily lost? 1 week? 1 month? 6 months? Thanks.

                Better to 301 or de-index 403 pages

                Google WMT recently found and called out a large number of old unpublished pages as access denied errors. The pages are tagged "noindex, follow."  These old pages are in Google's index. At this point, would it better to 301 all these pages or submit an index removal request or what? Thanks... Darcy

                Is a 404, then a meta refresh 301 to the home page OK for SEO?

                Hi Mozzers I have a client that had a lot of soft 404s that we wanted to tidy up. Basically everything was going to the homepage. I recommended they implement proper 404s with a custom 404 page, and 301 any that really should be redirected to another page. What they have actually done is implemented a 404 (without the custom 404 page) and then after a short delay 301 redirected to the homepage. I understand why they want to do this as they don't want to lose the traffic, but is this a problem with SEO and the index? Or will Google treat as a hard 404 anyway? Many thanks

                Redirect Search Results to Category Pages

                I am planning redirect the search results to it's matching category page to avoid having two indexed pages of essentially the same content. Example http://www.example.com/search/?kw=sunglasses
                wil be redirected to
                http://www.example.com/category/sunglasses/ Is this a good idea? What are the possible negative effect if I go this route? Thanks.

                Why does my home page show up in search results instead of my target page for a specific keyword?

                I am using Wordpress and am targeting a specific keyword..and am using Yoast SEO if that question comes up.. and I am at 100% as far as what they recommend for on page optimization. The target html page is a "POST" and not a "Page" using Wordpress definitions. Also, I am using this Pinterest style theme here http://pinclone.net/demo/ - which makes the post a sort of "pop-up"  - but I started with a different theme and the results below were always the case..so I don't know if that is a factor or not. (I promise .. this is not a clever spammy attempt to promote their theme - in fact parts of it don't even work for me yet so I would not recommend it just yet...) I DO show up on the first page for my keyword.. however.. instead of Google showing the page www.mywebsite.com/this-is-my-targeted-keyword-page.htm Google shows www.mywebsite.com in the results instead. The problem being - if the traffic goes only to my home page.. they will be less likely to stay if they dont find what they want immediately and have to search for it.. Any suggestions would be appreciated!

                Paging. is it better to use noindex, follow

                Is it better to use the robots meta noindex, follow tag for paging, (page 2, page 3) of Category Pages which lists items within each category or just let Google index these pages Before Panda I was not using noindex because I figured if page 2 is in Google's index then the items on page 2 are more likely to be in Google's index. Also then each item has an internal link So after I got hit by panda, I'm thinking well page 2 has no unique content only a list of links with a short excerpt from each item which can be found on each items page so it's not unique content, maybe that contributed to Panda penalty. So I place the meta tag noindex, follow on every page 2,3 for each category page. Page 1 of each category page has a short introduction so i hope that it is enough to make it "thick" content (is that a word :-))  My visitors don't want long introductions, it hurts bounce rate and time on site. Now I'm wondering if that is common practice and if items on page 2 are less likely to be indexed since they have no internal links from an indexed page Thanks!

                All page files in root? Or to use directories?

                We have thousands of pages on our website; news articles, forum topics, download pages... etc - and at present they all reside in the root of the domain /. For example: /aosta-valley-i6816.html
                /flight-sim-concorde-d1101.html
                /what-is-best-addon-t3360.html We are considering moving over to a new URL system where we use directories.  For example, the above URLs would be the following: /images/aosta-valley-i6816.html
                /downloads/flight-sim-concorde-d1101.html
                /forums/what-is-best-addon-t3360.html Would we have any benefit in using directories for SEO purposes?  Would our current system perhaps mean too many files in the root / flagging as spammy?  Would it be even better to use the following system which removes file endings completely and suggests each page is a directory: /images/aosta-valley/6816/
                /downloads/flight-sim-concorde/1101/
                /forums/what-is-best-addon/3360/ If so, what would be better: /images/aosta-valley/6816/ or /images/6816/aosta-valley/ Just looking for some clarity to our problem! Thank you for your help guys!
