About Google Spider
-
Hello, people!
I have some questions regarding on Google spider.
Many people are saying that "Google spiders only have US IP address."
Is this really true?
But I also saw video from Google's offical blog and it said "Google spider come from all around the world."
At this point I am really confused.
Q1) I researched and it seems like Google spiders have only US IP address. THen what does exactly mean by "Google spider come from all around the world."?
Q2) If Google spider have only US IP address, what happen to site which use IP delivery?
Is this means that Google spider always redirect to us site since they only have US IP?
Can anyone help me to understand??
One more questions! When Google analyzing for cloaking issue, do you think Google analyze when spider crawls the site or after they crawled the site?

I think some of the confusion may be due to Google's primarily using IP addresses assigned to their headquarters in Mountain View, California. Google has many (around 20) data centers located outside the US. I recall reading an article whereby at times they used their Mountain View IPs from centers around the world. For security reasons they do not wish the location of all their data centers to be known.
I researched this topic before and I was unable to locate any official information from Google. It would only seem reasonable they crawl from all over the world. If they didn't, then a lot of sites which use geo-based targeting for site navigation would not have most of their content indexed. While it's true a sitemap could be used to overcome the issue, many sites do not use sitemaps and they still get indexed.

I do not believe this is true, Google has data centers all over the world in which they crawl from.
Google does not only have spiders crawling from US data centers.
I also have the feeling crawls are based on many factors such as link diversity per region, TLD of domain per region, PR user (still a crawling factor imo) and many more factors.
Overall do not stress Google can crawl from various regions all over the globe, I would be more worried about geo server location and TLD of your domain and also local links.
Kind Regards,
James Norquay.

Structured Data - How frequent does Google update?
Hi all, I recently updated some markup on my site about a week ago. However, when using the structured data testing tool and inserting the URL of the page that was updated with the schema, I see that the schema being recognized does not reflect the updated markup. However, when I use the structured data testing tool again and insert the code I used for the schema, I see no errors and all info was implemented properly. Any idea why my updates (which seem to be correct based on my code) are not reflecting when testing the URL of my site via structured data testing tool? Is there some delay for this data to update? Any insight would be much appreciated. Thanks all in advance! Best,

Google Published Date - Does Google Lie?
Here's the scenario. I create a page called "ABC" and it gets published and found by Google lets say on the 13th of April. on the 15th (or 14th) i decide to update the URL, page Title, and content. (Redirect old URL to new URL as well) Will Google still show this page as being published on the 13th? or would it update the publish date according to the new URL?

Google having trouble accessing my site
Hi google is having problem accessing my site. each day it is bringing up access denied errors and when i have checked what this means i have the following Access denied errors In general, Google discovers content by following links from one page to another. To crawl a page, Googlebot must be able to access it. If you’re seeing unexpected Access Denied errors, it may be for the following reasons: Googlebot couldn’t access a URL on your site because your site requires users to log in to view all or some of your content. (Tip: You can get around this by removing this requirement for user-agent Googlebot.) Your robots.txt file is blocking Google from accessing your whole site or individual URLs or directories. Test that your robots.txt is working as expected. The Test robots.txt tool lets you see exactly how Googlebot will interpret the contents of your robots.txt file. The Google user-agent is Googlebot. (How to verify that a user-agent really is Googlebot.) The Fetch as Google tool helps you understand exactly how your site appears to Googlebot. This can be very useful when troubleshooting problems with your site's content or discoverability in search results. Your server requires users to authenticate using a proxy, or your hosting provider may be blocking Google from accessing your site. Now i have contacted my hosting company who said there is not a problem but said to read the following page http://www.tmdhosting.com/kb/technical-questions/other/robots-txt-file-to-improve-the-way-search-bots-crawl/ i have read it and as far as i can see i have my file set up right which is listed below. they said if i still have problems then i need to contact google. can anyone please give me advice on what to do. the errors are responce code 403 User-agent: *

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.

Does Google monitor which links are actually followed?
If a link to my site is posted on another site and many people start following that link and they stay on my site for a while, and I also have GA set up, does Google factor that information back into the Google rankings? In other words, are there ways that Google tries to use clicks and bounce rates and other user behavior to determine page rank and domain rank? Best,

Google places listing gone crazy
I have a google places listing that was doing great and was consantly on the top 3 for most of it's keywords. About 3 weeks ago google declined my listing (it was on the same account with other listings that violated google guidelines). The listing still showed up on google while it being reviewed (i assumed that it because this listing didn't violate an guideline.) About a week ago google started showing reviews from Insiderpages with my listing that belonged to a competitor. Today, they fixed that and added a link to my right insiderpages page but weird things started to happen.... My listing started to appear as a NON VERIFIED liting. My website is no longer on the listing. The phone number listed on the listing belong to a competitor!! All the citations are still mine including one from my site! Should i report it to google? i'm hesitating to do so, we are loosing a lot of business as it is with most of our listings down and i'm afraid this might be a small error that if i'll address will take longer to solve. My listing link: http://maps.google.com/maps/place?um=1&ie=UTF-8&q=appliance+repair+nyc&fb=1&gl=us&hq=appliance+repair&hnear=0x89c24fa5d33f083b:0xc80b8f06e177fe62,New+York,+NY&cid=14321731230878083852&ei=01AXTum3J4mmsQKl_KxS&sa=X&oi=local_result&ct=placepage-link&resnum=9&ved=0CJ0BEOIJMAg Thanks!!
