Google Giving 404 Errors to Working Pages
-
We have a problem that just came up out of the blue with Google, in particular Webmaster Tools & our Merchant Center. We're getting a 404 errors for 1000s of pages in both of these applications, but the pages are working just fine. Our shopping campaigns have been hit hard as many of our top products have been suspended from our merchant feed. Webmaster tools is giving us 1000s of 404 errors to product & category pages alike. But every page returning a 404 error is working. We've contacted Google and they mention that they are not getting a 404 error, but their crawler seems to be. Has anyone ever experienced this? What could be causing this?
Thanks for any input.

Hi Paul, what is the status of this issue? Has it been resolved, or not? Would love an update! Thanks ~ Christy

Yes, attackers use code injection techniques to hijack search results. They in fact do use some randomization techniques to make it harder to detect. Conducting a security scan using a tool like Sucuri.net could be helpful but manually reviewing your .htaccess and code may be necessary.

Thanks jeff-rackaid.com.
The idea of some sort of fowl play did cross our minds. These errors seemed to appear out of the blue without any significant code changes on our side.
We have done a fetch as Googlebot on a number of pages. We had found that the returns have been inconsistent; we would fetch a particular page and get a "Not found" error one minute and then a "complete" result the next minute. I don't think this is a normal activity.
We've also been tracking the traffic of Googlebot to our site and since Thursday (8/14), the hits from GoogleBot have been going down while the hits from an "unknown bot" have been increasing.

This could just be a WMT error. I've seen this from time to time. If it persists for more than 24 hours, then you may want to try digging into it further.
Have you tried fetching as Googlebot
In doing server security work, I have seen some hijacking attempts that will send 301 responses to Googlebot. In some cases, these scripts are improperly deployed resulting in 404 errors or 500 errors. So I would first fetch the site as Googlebot.
Then examine your server's access logs for hits from Googlebot. Confirm that it is indeed Googlebot. You can verify Googlebot IP ranges with reverse DNS:

If there's no foul play, then check for any browser-based detections routines. With the increasing use of mobile, I have seen some code fail to handle bots correctly. The behavior is usually an error not a 404. However, many CMS systemincorrectly send 404 errors for a variety of errors and not just true not found status codes.

100+ PPC Landing Pages Linking To Main URL... Hurting My SEO?
I started another thread around this question but don't think I was articulate enough. So, I have over 100 various landing pages that I use for targeted PPC. I don't really have any interest in these pages amassing their own SEO value; I simply use them for my PPC accounts. However, they all link back to my home page. Is this considered a link farm? And, if so, is the best option to simply add a nofollow attribute to all the links pointing to my home page? Would there be any reason to keep the links as follow? I don't think they're giving my site any SEO value but I'm concerned that they could be harming it instead. Any expert advice would be much appreciated.

Adwords Expanded Text Ads - How are they working for you?
I think it would be nice to get a consensus from more people. The day expanded text ads came out last week, I immediately jumped on it and created them for all my campaigns. I still left some of the old ads running in each ad group so that I could compare. Looking at the conversion data from the last week, the conversion rates are between 2-7x lower on the expanded text ads, and as a result, the cost per conversion is 2-5x higher as well. Basically, they're performing horribly. The click-through rate is mildly higher, but who cares if they're not converting? I know it's only a week's worth of data, but it seems the difference is enough to be statistically significant. I'm wording what everyone else's experience has been.

Adding Coremetrics Tags with Google Adwords
Hello, I would like to know if it's possible to add Coremetrics tracking tags in Google Adwords while the auto tagging functionnality is on. The point of doing this is to be able to track in both Analytics systems the performance of the PPC campaigns while still having Adwords to use Google Analytics conversion data. Thanks, Guillaume

Why you should never use Google Adwords To Conduct Key Word Research
Buongiorno from 22 degrees C too damn humid Wetherby UK, The other day a client wanted to know how much a ppc campaign would cost with a specific bank of keywords. So off i went and loaded in the key words and set the ads thinking it was not live.... A week later i get a tap on the shoulder asking why weve been invoiced for £xxxx oh dio mio!! The damn campaign went to live. So ive got two questions: 1. Do Google adwords automatically go to Live once youve loaded up phrases and ads, i really thought it would have made it more obvious, A " Would you like your campaign to go live" prompt would have been appreciated. 2. As a safety measure is configuring a Google Alert in Analytics to ping when paid traffic is picked up not a bad idea just so ive got a warning sytem set up so to speak. Grazie tanto,

A question for Google Adwords experts
Hi Google Adwords experts, We own the trademarks to some keywords. When you search for these keywords, only our ads will ever appear but they don't appear every time a search is made. They're hardly ever appearing now that we've dropped our bid from $1+ to the minimum first page bid (1 cent in some cases). My question is; are the ads showing less because our bid has dropped so low? If so, why is this? If we own the trademark to the keyword and no one else can display ads, any bid that we submit should be accepted by Google, shouldn't it? If you can include a link to any articles that will give me more info, i'll vote for your answer. Thanks!

New v Returning in Google Analytics with Adwords
I am trying to figure out an issue with Google Analytics. What i am stumped on is I see traffic from AdWords coming in (accounts linked) and I see new v returning user. Does the return visit still show even if a user came back in via direct or organic? Or is it that these return visits are clicking on the ad again to come back as visits and clicks match in the reports?
