Question relates to mobile site & duplicate content.
-
We are working on the mobile version of a large site (migraine.com) and will be using a separate theme for it (directing visitors to m.migraine.com)- what are the necessary code or other important step we should take so that we do get penalized for having duplicate content? Thank you in advance for your responses

Interesting point! However, we are creating a mobile site in html5 to serve smartphones only. On a seperate domain, m.example.com. From what I have read Google treats smartphones as desktops due to thier advanced web browser capabilities.
So no need to bother with googlebot.mobile right? Googlebot should index
the site once I create a normal sitemap.xml. My concern is that the mobile site
pulls the same content as the main site which is already indexed.Would this create duplicate content? If so, what can I do?

1. Detect crawler type. If it's the mobile googlebot, and it comes to the regular site, redirect it to the mobile site. If the regular googlebot comes to the mobile site, redirect it to the regular site. You should also do this as a best practice based on all visitor browser types. It's not cloaking, it's serving up the proper version of the site to the source it belongs with. You can see Matt Cutt's help video on this subject here.
2.Create a mobile sitemap file and submit it to Google and Bing.
If you do this properly, you should not have any problems with duplicate content because they're sophisticated enough to understand that you're not trying to serve up two sets of content to the same visitor type.

By Using interstitial (popups) on the webiste, will google penalize ranks for desktop and mobile both ?
We have implemented interstitials (pop-ups) on a website (Business Articles Website). The popups are basically used for getting leads from the website (using Signup popups). Before Popup implementation the traffic was steady, After the implementation, the traffic started to decay after a couple of weeks and due to the drop we disabled the popup from the website and initiated a force crawl and within next few weeks, we observed traffic gaining back to its normal trend. Within these timelines drop in desktop traffic was more and mobile traffic remain steady. As per Google guidelines, interstitials are more likely to be affected on mobile than desktop. But in our case, desktop traffic was hit more than mobile. So we carried out this experiment for 3 months. And we observed traffic decay and regain. Is interstitials the only culprit here (as the drop is only in desktop) or Can there be some other reasons as well for the traffic drop? bF7hc

Does omitted results shown by Google always mean that website has duplicate content?
Google search results for a particular query was appearing in top 10 results but now the page appears but only after clicking on the " omitted results by google." My website lists different businesses in a particular locality and sometimes results for different localities are same because we show results from nearby area if number of businesses in that locality (search by users) are less then 15. Will this be considered as "duplicate content"? If yes then what steps can be taken to resolve this issue?

Why does Google say they have more URLs indexed for my site than they really do?
When I do a site search with Google (i.e. site:www.mysite.com), Google reports "About 7,500 results" -- but when I click through to the end of the results and choose to include omitted results, Google really has only 210 results for my site. I had an issue months back with a large # of URLs being indexed because of query strings and some other non-optimized technicalities - at that time I could see that Google really had indexed all of those URLs - but I've since implemented canonical URLs and fixed most (if not all) of my technical issues in order to get our index count down. At first I thought it would just be a matter of time for them to reconcile this, perhaps they were looking at cached data or something, but it's been months and the "About 7,500 results" just won't change even though the actual pages indexed keeps dropping! Does anyone know why Google would be still reporting a high index count, which doesn't actually reflect what is currently indexed? Thanks!

How to speed up indexing of my site...
Only 4 out of the 12 pages of my blog/site have been indexed. How can I ensure all the pages get indexed? I'm using a wordpress site, and I also wondered how could I speed the indexing process up (I have submitted a site map) Thanks!

Related Searches in Google
Hello, We're helping a client remove/minimize some negative information about their brand in Google's search results. Just curious about your take on if the related searches that appear at the bottom of Google search results can in any way be influenced or if it is more a combination of so many factors that any one person or organization wouldn't be able to change very easily? I've heard the related results could be influenced if enough queries generated overtake the "negative" queries done initially but I feel like that is venturing into black hat land a bit. thanks -Mike

Can you help with a few high-level mobile SEO questions?
Rolling out a mobile site for a client and I'm not positive about the following: Do these mobile pages need to be optimized with the same / similar page titles? If we have a product page on the regular site with an optimized title like "Men's Sweaters, Shirts and Ties - Company XYZ", should the mobile version's page have the same title? What if the dev team simply named it "Company XYZ Clothes" and missed the targeted keywords? Does it matter? Along the lines of question 1, isn't there truly just one index and your regular desktop browser version will be used for all ranking factors on both desktop and mobile SERPs? If that regular page indeed ranks well for "men's sweaters" and that term is searched on a mobile device, the visitor will be detected and served up the mobile page version, regardless of its meta tags and authority (say it's on a subdomain, m.example/.com/mens-department/ ), correct? Are meta descriptions necessary for the mobile version? Will the GoogleBot Mobile recognize them or will just the regular version work? Looks like mobile meta descriptions have about 30 less characters. Thanks in advance. Any advice is appreciated. AK

Seaches & Clicks Research
Is there a way to check the percentage of clicks on specific websites based on searches that people do? For example, say I searched "sneakers", what percentage of viewers clicked on a particular site.
