How do I complete a reverse DNS check when completing log file analysis?
-
I'm doing some log file analysis and need to run a reverse DNS check to ensure that I'm analysing logs from Google and not any imposters. Is there a command I can use in terminal to do this?
If not, whats the best way to verify Googlebot?
Thanks

That's awesome! Glad to know there's a bulk tool out there!

Hi Tyler,
Thanks for your reply. I managed to get down to 98 unique IPs and ran a bulk reverse DNS/IP Look-up using this tool:

Thanks for your help though!

Hey Daniel,
If you want to verify that a user-agent is actually Googlebot, you'll want to use a log file analysis tool to aggregate all of the IP addresses associated with Googlebot. Once you have a list of IP addresses, you can perform a reverse DNS lookup to verify whether the IP addresses are actually associated with Googlebot or not.
If you're on windows/pc these steps should work:
https://www.serverintellect.com/support/dns/reverse-dns/If you're on mac try these steps:
1. open Terminal
2. type "host" + ip address
for example: "host 66.249.66.1"
3. hit enter
4. view results. For example: "1.66.249.66.in-addr.arpa domain name pointer crawl-66-249-66-1.googlebot.com"If the results are from Google.com or Googlebot.com, you can be sure it's actually Google crawling your site. Unfortunately, I don't know of any faster ways to achieve these results. I'm sure there's a tool out there, I just haven't found it yet.
This might also be a good resource for you: https://support.google.com/webmasters/answer/80553?hl=en
Good luck!

#302HTTP #temporaryredirect
Technical SEO | | Damian_Ed 0
Hi everyone, Recently I have faced a crawl issue with my media images on website. For example this page url https://intreface.com/wp-content/uploads/2022/12/Horion-screen-side-2.png has 302 HTTP Status and the recommendation is to change it 301. I have read the article on temporary redirections here:
https://moz.com/learn/seo/redirection?_ga=2.45324708.1293586627.1702571936-916254120.1702571936
but its not written here how to redirect in my HTML 1 image url not the landing page.

I have messaged to MOZ Support but they recommended to go for the MOZ Community!
Screenshot 2023-12-15 at 11.06.02.png Could you assist me wit this issue please? I can reach HTTML of the necessary page and change what I need for permanent redirection but firstly I need to understand how to do that correctly.0 -
PageSpeed Insights DNS Issue
Hi Anyone else having problems with Google's Pagespeed tool? I am trying to benchmark a couple of my sites but, according to Google, my sites are not loading. They will work when I run them through the test at one point but if I try again, say 15 mins later, they will present the following error message An error has occured DNS error while resolving DOMAIN. Check the spelling of the host, and ensure that the page is accessible from the public Internet. You may refresh to try again. If the problem persists, please visit the PageSpeed Insights mailing list for support. This isn't too much an issue for testing page speed but am concerned that if Google is getting this error on the speed test it will also get the error when trying to crawl and index the pages. I can confirm the sites are up and running. I the sites are pointed at the server via A-records and haven't been changed for many weeks so cannot be a dns updating issue. Am at a loss to explain. Any advice would be most welcome. Thanks.

Reverse proxy a successful blog from subdomain to subfolder?
I have an ecommerce site that we'll call confusedseo.com. I created a WordPress blog and CNAME'd it to blog.confusedseo.com. Since then, the blog has earned a PageRank of 3 and a decent amount of organic traffic. I am considering a reverse proxy to forward blog.confusedseo.com to confusedseo.com/blog/. As I understand it, this will greatly help the "link juice" of the root domain. However, I'm concerned about any potential harm done to the existing SEO value of the blog. What, if anything, should I be doing to ensure that the reverse proxy doesn't hurt my "juice" rather than help it?

Why are Google search results different if you are log'd into Google or not?
I get different results when I'm log'd into my Google account associated with my website than if I'm not. The same country is occurring. So how can I rely on the google results I'm seeing? For instance my site is page 1 with the improvements I made based on SEOMOZ if I'm log'd in. Yet I'm not on the first 25 pages if I'm not logged in.

How do I check if my IP is blocked?
We changed servers and where our sites once ranked very highly (page 1 for all sites), they now are nowhere to be seen. Someone suggested that our IP might be blocked. Someone else suggested SEOMoz was the place to go to get it checked. Any help would be GREATLY appreciated. With thanks. Bryan
