Does Google have a separate crawler for Javascript and Content?
-
Someone told me this is true.
-
Much similar to many of the rules and guidelines by which Google calculates search rankings, they don't openly provide that type of information to the general public, because obviously their users would take advantage of it and manipulate the crawlers for the purpose of altering their rankings.
If you wanted to know something like that for sure, you would probably need to conduct field research doing something extreme like having 100% javascript content in one segment of your site and 100% HTML on another and track which IPs and user agents hit the pages.
However an educated guess of mine believes this:
- The bots that crawl HTML also crawl Javascript. To make separate bots to do individual tasks would be stupid.
- there would be absolutely no benefit nor would the sanitation of the data the crawlers obtain be increased using seperate bots. Because it can be clearly concluded the difference between html and Javascript, and at an automated level as well.

Will Google View Using Google Translate As Duplicate?
If I have a page in English, which exist on 100 other websites, we have a case where my website has duplicate content. What if I use Google Translate to translate the page from English to Japanese, as the only website doing this translation will my page get credit for producing original content? Or, will Google view my page as duplicate content, because Google can tell it is translated from an original English page, which runs on 100+ different websites, since Google Translate is Google's own software?

Hi, we have a blog site xxxxxxxxxxx.es, that yesterday dissapear from google ranks all of a sudden it only appears if you write xxxxxxxxx.es I have checked gogle webmaster tools and there are no manual actions, no messages. Also, we don't have much links pointing to this site. Webmaster tools show only 319 links. We don't understand what have happenned. Never see something similar. What do you think? Any help would be appreciated. How do you proceed in this cases? It doesn't seem to be a link problem. How do you know what kind of penalty do you have? Thank you. Update: Hi, the domain is www.crearcorreoelectronico.es I have check the majestic seo, ose, and wmt and get the links. We have some links that are not good, but are automatic ones, that some portals generate. Maybe is something related with the content. I don't know Thanks

Google is displaying wrong address
I have a client whose Google Places listing is not showing correctly. We have control of the page, and have the address verified by postcard. Yet when we view the listing it shows a totally different address that is miles away and on a totally different street. We have relogged into manage the business listing and all of the info is correct. We dragged the marker and submitted it to them that they had things wrong and left a note with the right address. Why would this happen and how can we fix it? Right now they rank highly but with a blatantly wrong address.

Same content pages in different versions of Google - is it duplicate>
Here's my issue I have the same page twice for content but on different url for the country, for example: www.example.com/gb/page/ and www.example.com/us/page So one for USA and one for Great Britain. Or it could be a subdomain gb. or us. etc. Now is it duplicate content is US version indexes the page and UK indexes other page (same content different url), the UK search engine will only see the UK page and the US the us page, different urls but same content. Is this bad for the panda update? or does this get away with it? People suggest it is ok and good for localised search for an international website - im not so sure. Really appreciate advice.

Duplicate page content query
Hi forum, For some reason I have recently received a large increase in my Duplicate Page Content issues. Currently it says I have over 7,000 duplicate page content errors! For example it says: Sample URLs with this Duplicate Page Content http://dikelli.com.au/accessories/gowns/news.html http://dikelli.com.au/accessories/news.html

http://dikelli.com.au/gallery/dikelli/gowns/gowns/sale_gowns.html However there are no physical links to any of these page on my site and even when I look at my FTP files (I am using Dreamweaver) these directories and files do not exist. Can anyone please tell me why the SEOMOZ crawl is coming up with these errors and how to solve them?0 -
Duplicate content mess
One website I'm working with keeps a HTML archive of content from various magazines they publish. Some articles were repeated across different magazines, sometimes up to 5 times. These articles were also used as content elsewhere on the same website, resulting in up to 10 duplicates of the same article on one website. With regards to the 5 that are duplicates but not contained in the magazine, I can delete (resulting in 404) all but the highest value of each (most don't have any external links). There are hundreds of occurrences of this and it seems unfeasible to 301 or noindex them. After seeing how their system works I can canonical the remaining duplicate that isn't contained in the magazine to the corresponding original magazine version - but I can't canonical any of the other versions in the magazines to the original. I can't delete the other duplicates as they're part of the content of a particular issue of a magazine. The best thing I can think of doing is adding a link in the magazine duplicates to the original article, something along the lines of "This article originally appeared in...", though I get the impression the client wouldn't want to reveal that they used to share so much content across different magazines. The duplicate pages across the different magazines do differ slightly as a result of the different Contents menu for each magazine. Do you think it's a case of what I'm doing will be better than how it was, or is there something further I can do? Is adding the links enough? Thanks. 🙂

Why does this page not show in google at all?
www.lavenderblue-flowers.co.uk Sorry for formatting, below is the source. There are alot of blocks from robots.txt but is there anything easily rectified to get this site SOME visibility? Duplicate content maybe PANDA had it? No backlink profile too which isnt helping but even still, surprising to see a domain auth of 1. Thanks in advance for any responses.
