      I have a client with a lot of 404 errors from Web Master Tools, and i have to go through and check each of the links because

      • Some redirect to the correct page
      • Some redirect to another url but its a 404 error
      • Some are just 404 errors

      Does anyone know of a tool where i can dump all of the urls and it will tell me

      • If the url is redirected, and to where
      • if the page is a 404 or other error

      Any tips or suggestions will be really appreciated!

      Thanks SEO Moz'rs

        Check out the free Xenu Link Sleuth and this post: http://www.seomoz.org/blog/xenu-link-sleuth-more-than-just-a-broken-links-finder

        I haven't used it myself (yet), but Screaming Frog could help as an alternative, though the full version is paid. This post compares the two: http://www.seomoz.org/blog/crawler-faceoff-xenu-vs-screaming-frog

          Have you tried the SEOmoz Crawl Diagnostics report? That will show the 404 errors and the pages on the site that have the links to those pages.

            Google Search Console Showing 404 errors for product pages not in sitemap?

            search console 404 error 404s

            We have some products with url changes over the past several months. Google is showing these as having 404 errors even though they are not in sitemap (sitemap shows the correct NEW url). Is this expected? Will these errors eventually go away/stop being monitored by Google?

            Best Practice for www and non www

            How is the best way to handle all the different variations of a website in terms of www | non www | http | https? In Google Search Console, I have all 4 versions and I have selected a preference. In Open Site Explorer I can see that the www and non www versions are treated differently with one group of links pointing to each version of the same page. This gives a different PA score. eg. http://mydomain.com DA 25 PA 35 http://www.mydomain.com DA 19 PA 21 Each version of the home page having it's only set of links and scores. Should I try and "consolidate" all the scores into one page? Should I set up redirects to my preferred version of the website? Thanks in advance

            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,

            404 error - but I can't find any broken links on the referrer pages

            Hi, My crawl has diagnosed a client's site with eight 404 errors. In my CSV download of the crawl, I have checked the source code of the 'referrer' pages, but can't find where the link to the 404 error page is. Could there be another reason for getting 404 errors? Thanks for your help. Katharine.

            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.

            What is the best URL designed for a product page?

            Should a product page URL include the category name and subcategory name in it? Most ecommerce platforms it seems are designed to do have the category and sub-category names included in the URL followed by the product name. If that is the case and the same product is listed in more then 1 category and sub-category then will that product have 2 unique urls and as a result be treated as 2 different product pages by google?   And then since it is the same product in two places on the site won't google treat those 2 pages as having duplicate content? SO is it best to not have the category and sub-category names in the URL of a product page? And lastly, is there a preferred character limit for a URL to be less than in size? Thanks!

            404 crawl errors from "tel:" link?

            I am seeing thousands of 404 errors.  Each of the urls is like this: abc.com/abc123/tel:1231231234 Everything is normal about that url except the "/tel:1231231234" these urls are bad with the tel: extension, they are good without it. The only place I can find this character string is on each page we have this code which is used for Iphones and such.  What are we doing wrong? Code: Phone: <a href="[tel:1231231234](tel:7858411943)"> (123) 123-1234a>
