      Not a techie here...maybe this is to be expected, but ever since one of my client sites has switched to TLS 1.3, I've had a couple of crawl issues and other hiccups.

      First, I noticed that I can't use HTTPSTATUS.io any more...it renders an error message for URLs on the site in question. I wrote to their support desk and they said they haven't updated to 1.3 yet. Bummer, because I loved httpstatus.io's functionality, esp. getting bulk reports.

      Also, my Moz campaign crawls were failing. We are setting up a robots.txt directive to allow rogerbot (and the other bot), and will see if that works. These fails are consistent with the date we switched to 1.3, and some testing confirmed it.

      Anyone else seeing these types of issues, and can suggest any workarounds, solves, hacks to make my life easier? (including an alternative to httpstatus.io...I have and use screaming frog...not as slick, I'm afraid!)

      Do you think there was a configuration error with the client's TLS 1.3 upgrade, or maybe they're using a problematic/older version of 1.3??

      Thanks -

        GoogleBot still crawling HTTP/1.1 years after website moved to HTTP/2

        google http https indexation crawl

        Whole website moved to https://www. HTTP/2 version 3 years ago. When we review log files, it is clear that - for the home page - GoogleBot continues to only access via HTTP/1.1 protocol Robots file is correct (simply allowing all and referring to https://www. sitemap Sitemap is referencing https://www. pages including homepage Hosting provider has confirmed server is correctly configured to support HTTP/2 and provided evidence of accessing via HTTP/2 working 301 redirects set up for non-secure and non-www versions of website all to https://www. version Not using a CDN or proxy GSC reports home page as correctly indexed (with https://www. version canonicalised) but does still have the non-secure version of website as the referring page in the Discovery section. GSC also reports homepage as being crawled every day or so. Totally understand it can take time to update index, but we are at a complete loss to understand why GoogleBot continues to only go through HTTP/1.1 version not 2 Possibly related issue - and of course what is causing concern - is that new pages of site seem to index and perform well in SERP ... except home page. This never makes it to page 1 (other than for brand name) despite rating multiples higher in terms of content, speed etc than other pages which still get indexed in preference to home page. Any thoughts, further tests, ideas, direction or anything will be much appreciated!

        Moz crawler is not able to crawl my website

        moz crawler

        Hi, i need help regarding Moz Can't Crawl Your Site i also share screenshot that Moz was unable to crawl your site on Mar 26, 2022. Our crawler was not able to access the robots.txt file on your site. This often occurs because of a server error from the robots.txt. Although this may have been caused by a temporary outage, we recommend making sure your robots.txt file is accessible and that your network and server are working correctly. Typically errors like this should be investigated and fixed by the site webmaster.
        my robts.txt also ok i checked it
        Here is my website https://whiskcreative.com.au
        just check it please as soon as possibe

        Indexing Issue of Dynamic Pages

        Hi All, I have a query for which i am struggling to find out the answer. I unable to retrieve URL using "site:" query on Google SERP. However, when i enter the direct URL or with "info:" query then a snippet appears. I am not able to understand why google is not showing URL with "site:" query. Whether the page is indexed or not? Or it's soon going to be deindexed. Secondly, I would like to mention that this is a dynamic URL. The index file which we are using to generate this URL is not available to Google Bot. For instance, There are two different URL's. http://www.abc.com/browse/ --- It's a parent page.
        http://www.abc.com/browse/?q=123 --- This is the URL, generated at run time using browse index file. Google unable to crawl index file of browse page  as it is unable to run independently until some value will get passed in the parameter and is not indexed by Google. Earlier the dynamic URL's were indexed and was showing up in Google for "site:" query but now it is not showing up. Can anyone help me what is happening here? Please advise. Thanks

        Redirect and ranking issue

        Hi there - was wondering whether someone might be able to help. For a period of a day and a half, all the traffic to our website's blog articles were mistakenly being redirected to our homepage. A number of these articles ranked in the top 5 in Google worldwide for their targeted keywords, so this was a considerable amount of organic traffic that was instantly being redirected. It was a strange site glitch and our web team rectified the error, but now all these articles have disappeared from Google rankings (not visible anywhere in the first five pages). I'm presuming this must be linked to this redirect issue - we've been advised to wait and see whether Google restores these rankings, but I'm still concerned as to whether this represents a more serious problem? We have re-indexed the pages we are most concerned about, but am not sure whether there is anything else obvious we should think to do. If anyone has any thoughts, I'd be happy to hear them!

        Crawl rate dropped to zero

        Hello, I recently moved my site in godaddy from cpanel to managed wordpress. I bought this transfer directly from GoDaddy customer service. in this process they accidentally changed my domain from www to non www. I changed it back after the migration, but as a result of this sites craw rate from search console fell to zero and has not risen at all since then. In addition to this website does not display any other errors, i can ask google manually fetch my pages and it works as before, only the crawl rates seems to be dropped permanently. GoDaddy customer service also claims that do not see any errors but I think, however, that in some way they caused this during the migration when the url changed since the timing match perfectly.  also when they accidentally removed the www, crawl rate of my sites  non www version got up but fell back to zero when I changed it back to www version. Now the crawl rate of both www and non www version is zero. How do I get it to rise again? Customer service also said that the problem may be related to ftp-data of search console?  But they were not able to help any more than .Would someone from here be able to help me with this in anyway please?

        Has anyone had issues with Bazaarvoice and schema.org?

        About a year ago we started using Bazaarvoice to get reviews for our products, and it has been great as far as accumulating content, but Google is not taking the schema.org data and displaying it on the SERP. Someone has told me it is because we are offering multiple products, or that our schema.org tags are incorrect but when I compare our code to other travel sites it seems like everyone is doing something different. This is especially annoying since the Google schema markup check says everything is fine. Does anyone have any advice or similar experiences? Thanks.

        Can too many pages hurt crawling and ranking?

        Hi, I work for local yellow pages in Belgium, over the last months we introduced a succesfull technique to boost SEO traffic: we have created over 150k of new pages, all targeting specific keywords and all containing unique content, a site architecture to enable google to find these pages through crawling, xml sitemaps, .... All signs (traffic, indexation of xml sitemaps, rankings, ...) are positive. So far so good. We are able to quickly build more unique pages, and I wonder how google will react to this type of "large scale operation": can it hurt crawling and ranking if google notices big volumes of content (unique content)? Please advice
