SEO Question - Are 503/504 errors an issue?
-
Lately I've noticed more and more 503/504 errors being flagged in my MOZ reports. One week I had over 1300 errors show up. I checked Google Webmaster Tools and Bing Webmaster tools and noticed they were showing up in there too, although not near as many (50 or less per day). I contacted my hosting company about it and they said these were normal and that it was due to one nameserver reaching capacity, but that there was a backup nameserver that kicks in. I've seen one or two of these errors show up before, but never more than one or two a week. Is this something I should be concerned about?

Thank you for the responses. I figured it can't be a good thing, but they made it sound like it wasn't impacting user experience because the switch to the available nameserver was immediate. It still seems to me that if Google Search Console is flagging 503/4 errors daily, as well as Bing WMT, there may be an issue. If it were only Bing, Google or MOZ I wouldn't be as concerned. Heck, I even ran a ScreamingFrog scan last night and got a handful of 504 errors. Going to be reaching out to them today to see about a fix. Thanks for your replies.

Agree with Lesley. 1300 is excessive, and even 50 sounds like a lot to me. Do you see any in Search Console? Would be interesting to see if this were corroborated by Google seeing similar.

I personally would say and a pretty major one. The issue is that your site is going down more than likely when it is crawled.
As far as what the hosting company that is more than likely the case, but that does not make it acceptable. I would either move hosting companies, host your name services somewhere else, or have them move you to a different cluster.

Is having the same title tag on a blog listing page and blog date archives an SEO issue?
Hi there, Can anyone answer whether having duplicate title tags on the blog listing page (e.g.https://blog.companyname.com/) and the blog date archive pages (e.g.https://blog.companyname.com/archive/2017/10) is an issue? If so why is it an issue and what are the best practices of dealing with this? Thanks! John

No descripton on Google/Yahoo/Bing, updated robots.txt - what is the turnaround time or next step for visible results?
Hello, New to the MOZ community and thrilled to be learning alongside all of you! One of our clients' sites is currently showing a 'blocked' meta description due to an old robots.txt file (eg: A description for this result is not available because of this site's robots.txt) We have updated the site's robots.txt to allow all bots. The meta tag has also been updated in WordPress (via the SEO Yoast plugin) See image here of Google listing and site URL: http://imgur.com/46wajJw I have also ensured that the most recent robots.txt has been submitted via Google Webmaster Tools. When can we expect these results to update? Is there a step I may have overlooked? Thank you,

<sub>& <sup>tags, any SEO issues?</sup></sub>
Hi - the content on our corporate website is pretty technical, and we include chemical element codes in the text that users would search on (like S02, C02, etc.) A lot of times our engineers request that we list the codes correctly, with a <sub>on the last number. Question - does adding this code into the keyword affect SEO? The code would look like SO<sub>2</sub>.</sub> Thanks.

Also, we are looking to remove "hyphen" www.ide-home.com.au in our domain name, again it is all about 301 redirecting. We need SEO expert to help us with all changes that minimize the effect on Google. Does anyone can suggest which company or who we can ask for help? Thanks very much.

Keyword density question.
For instance, if the keyword I'm targeting on a specific page is "New Orleans", the Keyword is everywhere it's supposed to be, title, meta, content, internal links, etc, .... So when I check my most relative key words with different tools, it always breaks the word up like: new - 12 times 2.3% orleans - 12 times 2.3% Should I try to fix this? or is this normal? and does google view this as 1 keyword when evaluating my site?

Home Page Indexing Question/Problem
Hello Everyone, Background: I recently decided to change the preferred domain settings in WM Tools from the non www version of my site to the www version. I did this because there is a redirect from the non www to the www and I've built all of my internal links with the www. Everything I read on SEO Moz seemed to indicate that this was a good move. Traffic has been down/volatile but I think it's attributable mostly to a recent site change/redesign. Having said that the preferred domain change did seem to drop traffic an additional notch. I made the move two weeks ago. Here is the question: When I google my site, the home page shows up as the site title without the custom title tags I've written. The page that displays in the SERP is still the non www version of the site. a site:www.mysite.com search shows an internal page first but doesn't return the home page as a result. All other pages pop up indexed with the www version of the page. a site:mysite.com (notice lack of www) search DOES SHOW my home page and my custom title tags but with a non www version of the page. All other pages pop up indexed with the www version of the page. Any one have thoughts on this? Is this a classic example of waiting on Google to catch up with the changes to my tiny little site?

Issue with 'Crawl Errors' in Webmaster Tools
Have an issue with a large number of 'Not Found' webpages being listed in Webmaster Tools. In the 'Detected' column, the dates are recent (May 1st - 15th). However, looking clicking into the 'Linked From' column, all of the link sources are old, many from 2009-10. Furthermore, I have checked a large number of the source pages to double check that the links don't still exist, and they don't as I expected. Firstly, I am concerned that Google thinks there is a vast number of broken links on this site when in fact there is not. Secondly, why if the errors do not actually exist (and never actually have) do they remain listed in Webmaster Tools, which claims they were found again this month?! Thirdly, what's the best and quickest way of getting rid of these errors? Google advises that using the 'URL Removal Tool' will only remove the pages from the Google index, NOT from the crawl errors. The info is that if they keep getting 404 returns, it will automatically get removed. Well I don't know how many times they need to get that 404 in order to get rid of a URL and link that haven't existed for 18-24 months?!! Thanks.
