503 Error or 200 OK??
-
So, in a Moz crawl and a Screaming From crawl, I'm getting some 503 Service Unavailable responses on the some pages.
So I go to the pages in question, and the Moz bar is showing a 200 OK. The SEOBook http status checker (http://tools.seobook.com/server-header-checker/) also shows a 200 OK.
What gives?
The only reason I'm looking at this is because rankings plummeted a couple of weeks ago.
Thanks!
UPDATE
So, I decided to use the mozbar to set the user agent as Googlebot and when I tried to access the pages in question I receive this message. I don't think this is an issue... anyone else have much experience here?
Your access to this site has been limited
Your access to this service has been temporarily limited. Please try again in a few minutes. (HTTP response code 503)
Reason: Fake Google crawler automatically blocked
Important note for site admins: If you are the administrator of this website note that your access has been limited because you broke one of the Wordfence firewall rules. The reason you access was limited is: "Fake Google crawler automatically blocked".
If this is a false positive, meaning that your access to your own site has been limited incorrectly, then you will need to regain access to your site, go to the Wordfence "options" page, go to the section for Firewall Rules and disable the rule that caused you to be blocked. For example, if you were blocked because it was detected that you are a fake Google crawler, then disable the rule that blocks fake google crawlers. Or if you were blocked because you were accessing your site too quickly, then increase the number of accesses allowed per minute.
If you're still having trouble, then simply disable the Wordfence firewall and you will still benefit from the other security features that Wordfence provides.
If you are a site administrator and have been accidentally locked out, please enter your email in the box below and click "Send". If the email address you enter belongs to a known site administrator or someone set to receive Wordfence alerts, we will send you an email to help you regain access. Please read our FAQ if this does not work.

The problem is that plugin you are using, "Wordfence". It is probably picking up the crawls from Screaming Frog and Moz as DoS attacks because of the amount of requests from the same IPs.
You could either see if the plugin IP whitelisting or why don't you just remove that plugin and use CloudFlare, which is free and offer an even more robust security option + an included CDN.

Errors in my coding how significant is this regarding rankings ?
I posted a question on here yesterday about the homepage asking for advice regarding the content and then was told by two people were very helpful bbut moved over comment not on content but to say taht the major problem was that the coding on my website basically has too many errors which would result in me receiving lower rankings in the search engines. I realise this website is old-fashioned Dreamweaver template which was constructed several years ago which I've updated and I'm certainly not a professional, but I watch my Google analytics and there doesn't seem to be any significant change in the stats from this time last year. This is the site http://www.endeavourcottage.co.uk/ I realise the site is old format and has been around for several years it's just from customer feedback they seem to think it looks okay for the products old cottages but I guess technically it's not the best now. I have run a test using Silktide Nibbler - a free online service that gives you a good complete overview of your website with an overall score. And it did give my website an overall good score but did point out errors in the coding but when I checked some of my competitors near the top of Google for the short tail keywords some of them also have errors in their coding, very similar to my own error score.. I then went to Google Webmaster tools and there were no warning messages. So the big question is how important are these errors scores when it appears that most of the top competition also are in the same situation? I think it's quite possible I could do with a redesign using responsive design Best Alan

Issues with Moz producing 404 Errors from sitemap.xml files recently.
My last campaign crawl produced over 4k 404 errors resulting from Moz not being able to read some of the URLs in our sitemap.xml file. This is the first time we've seen this error and we've been running campaigns for almost 2 months now -- no changes were made to the sitemap.xml file. The file isn't UTF-8 encoded, but rather Content-Type:text/xml; charset=iso-8859-1 (which is what Moveable Type uses). Just wondering if anyone has had a similar issue?

Duplicate Errors found in my search
I have run my 1st site check with SEOMOZ and have 4000+ errors. The "duplicate Page Content" culprit appears to be a extended url that keeps showing as duplicating. This is only a customer log-in and can be redirected back to the main cust log in page, but is there a short way of doing it (rather than 4000x 301's)? The format of the url is: http://www.????.com.au/default/customer/account/login/referer/aSR0cDovL3d3dy1234YWNiYW Thanks

How to trace 4XX errors in campaign data?
I am trying to resolve a number of 4XX (Client Error) issues noted in my campaign report, but I have no idea where they are originating. All I get is the broken link, the status code, the page authority and the number of linking root domains. How do I identify where the erroring link originates? Is it coming from within my website, or from an external website? I have gone through my site in great detail looking for these links, but can't find any evidence of them. I also use a broken link detection plugin and it reports no problems whatsoever. Is there a way I can drill down into these 404 links and get more detail about where they are coming from?

Campaign 4XX error gives duplicate page URL
I ran the report for my site and had many more 4xx errors than I've had in the past month. I updated my .htaccess to include 301 statements based on Google Webmaster Tools Crawl Errors. Google has been reporting a positive downward trend in my errors, but my SEOmoz campaign has shown a dramatic increase in the 4xx pages. Here is an example of an 4xx URL page: http://www.maximphotostudio.net/engagements/266/inniswood_park_engagements/http:%2F%2Fwww.maximphotostudio.net%2Fengagements%2F266%2Finniswood_park_engagements%2F This is strange because URL: http://www.maximphotostudio.net/engagements/266/inniswood_park_engagements/ is valid and works great, but then there is a duplicate entry with %2F representing forward slashes and 2 http statements in each link. What is the reason for this?

Broken Links and Duplicate Content Errors?
Hello everybody, I’m new to SEOmoz and I have a few quick questions regarding my error reports: In the past, I have used IIS as a tool to uncover broken links and it has revealed a large amount of varying types of "broken links" on our sites. For example, some of them were links on my site that went to external sites that were no longer available, others were missing images in my CSS and JS files. According to my campaign in SEOmoz, however, my site has zero broken links (4XX). Can anyone tell me why the IIS errors don’t show up in my SEOmoz report, and which of these two reports I should really be concerned about (for SEO purposes)? 2. Also in the "errors" section, I have many duplicate page titles and duplicate page content errors. Many of these "duplicate" content reports are actually showing the same page more than once. For example, the report says that "http://www.cylc.org/" has the same content as "http://www.cylc.org/index.cfm" and that, of course, is because they are the same page. What is the best practice for handling these duplicate errors--can anyone recommend an easy fix for this?

Is there such thing as a site free from errors?
Or is this a given? I am new to SEO and SEOmoz. One of my campaigns is completley free of errors...the others are a work in progress. Now I realize that SEO is never done, but can a site actually be free of errors? If so... I just gave myself a pat on the back.
