Are these 'not found' errors a concern?
-
Our webmaster report is showing thousands of 'not found' errors for links that show up in javascript code.
Is this something we should be concerned about? Especially since there are so many?
-
Are they internal missing links or external missing links?
If internal, then that would be a big problem.You can click on the link that will show you three options. Error details, in sitemap or linked from. Make sure none are from sitemap.
If external, not so much a problem because it would be beyond your control as to who is trying to link to your site. My webmaster tools show missing links all the time from outside sources we have nothing to do with. I usually just contact the source and ask them to remove the link, or if its from a semi quality site Ill ask them to fix the link and give them the accurate url.
I would make sure you have a 404 error page setup for any bad urls linking to your site. Hope this helps.

Why are these URL's suddenly appearing in WMT?
One of our clients has suddenly experienced a sudden increase in crawl errors for smart phones overnight for pages which no longer exist and there are no links to these pages according to Google. There is no evidence as to why Google would suddenly start to crawl these pages as they have not existed for over 5 years, but it does come after a new site design has been put live. Pages do not appear to be in the index when a site search is used. There was a similar increase in crawl errors on desktop initially after the new site went live, but these quickly returned to normal. Mobile crawl errors only became apparent after this. There are some URL's showing which have no linking page detected so we don't know where these URL's are being found. WMT states "Googlebot couldn't crawl this URL because it points to a non-existent page". Those that do have a linking page are showing an internal page which also doesn't exist so it can't possibly link to any page. Any insight is appreciated. Andy and Mark at Click Consult.

Sitemap errors have disappeared from my Google Webmaster tools
Hi all, A week ago I had 66 sitemap errors related to href langs in my GWT. Now, all the errors are gone, and it shows no errors. We have not done any work to fix the errors. I wonder if anybody has experienced the same thing, of Google suddenly changing the criteria or the way they report on errors in Google Webmaster Tools. I would appreciate any insights from the community! Best regards Peru

What's Worse - 404 errors or a huge .htaccess file
We have changed our site architecture pretty significantly and now have many fewer pages (albeit with more robust content and focused linking). My question is, what should I do about all the 404 errors (keep in mind, I am only finding these in Bing Webmaster tools, not Moz or GWT)? Is it worse to have all those 404 errors (hundreds), or to have a massive htaccess file for pages that are only getting hits by the Bing crawlbot. Any insight would be great. Thanks

Does a GTLD extension 'count' as part of the target keyword?
Hopefully someone can shed some light on this for me. Reading about GTLDs, I came across this quote from TSO Host: 'What we don’t know is whether an extension can double up as a keyword, which is picked up by Google and treated identically to the rest of a domain name. I.e. - would ‘bristolguitars.music’ have more ranking potential than ‘bristolguitars.com’ as ‘music’ is a relevant search word?' Source: https://www.tsohost.com/blog/how-do-new-gtlds-affect-seo Does anyone know if a GTLD extension does double up as a keyword? For example, if Nike buys 'Nike.shoes', does this double as the keyword 'Nike shoes', or is Google and other search engines just looking at the domain name _before _the GTLD extension? I'm looking at .photography for examples (not my niche) and seeing folks are having mixed results ranking for 'Keyword + Photography', so would be keen to hear your thoughts.

Should I add 'nofollow' to site wide internal links?
I am trying to improve the internal linking structure on my site and ensure that the most important pages have the most internal links pointing to them (which I believe is the best strategy from Google's perspective!). I have a number of internal links in the page footer going to pages such as 'Terms and Conditions', 'Testimonials', 'About Us' etc. These pages, therefore, have a very large number of links going to them compared with the most important pages on my site. Should I add 'nofollow' to these links?

404 Error from site - is this normal?
I have been trying to clean up any 404 errors. We keep getting the following: URL /include/vdimgck.php referring domain http://www.856d.c@m/plus/feedback.php rendered domain unclickable by adding the "@" since I do not know if it is safe. I just turned off the trackbacks and pings in the blog since I saw it was producing duplicate content and from what I read it is not worth keeping those with Wordpress. is vdimgck.php anything some here instantly recognizes ? It tops all our 404 errors, seems like a lot of requests. Thanks!

404 Errors in Google Webmaster Tools
Hello, Google webmaster tools is returning our URLs as 404 errors: http://www.celebritynetworth.com/watch/D5GrrPEN9Oc/tom-mccarthy-floating/ When we enter the URL into the browser it loads the page just fine. Is there a way to determine why Google Webmaster Tools is returning a 404 error when the link loads perfectly fine in a browser? Thanks, Alex
