      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.

            Expired domain 404 crawl error

            I recently purchased a Expired domain from auction and after I started my new site on it, I am noticing 500+ "not found" errors in Google Webmaster Tools, which are generating from the previous owner's contents.Should I use a redirection plugin to redirect those non-exist posts to any new post(s) of my site? or I should use a 301 redirect? or I should leave them just as it is without taking further action? Please advise.

            Is there a way of changing the Permalink without getting the 404 Error?

            Hi, I am new to this all.. Is there a way of changing the permalink for example from: domain/content/ to domain/profile/ without receiving the 404 error message. It's just that since my website has been developed, some pages and their content have changed but the permalink still shows the name of the old page which may be confusing. Ps. Please use most simple language for explanations as I am really new to it. Thank you! Ve

            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.

            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!

            What is the best website structure for SEO?

            I've been on SEOmoz for about 1 month now and everyone says that depending on the type of business you should build up your website structure for SEO as 1st step. I have a new client click here   ( www version doesn't work)... some bugs we are fixing it now. We are almost finished with the design & layout. 2nd question have been running though my head. 1. What would the best url category for the shop be    /products/     - current url cat ex:   /products/door-handles.html 2. What would you use for the main menu as section for getting the most out of SEO. Personally i am thinking of making 2-3 main categories on the left a section where i can add content to it (3-4 paragraphs... images maybe a video).So the main page focuses on the domain name more and the rest of the sections would focus on specific keywords, this why I avoid cannibalization. Main keyword target is "door handles" Any suggestions would be appreciated.

            Which is the best wordpress sitemap plugin

            Does anyone have a recommendation for the best xml sitemap plugin for wordpress sites or do you steer clear of plugins and use a sitemap generator then load it up to the root manually?
