Hi all, I have a question regarding changing the size of my sitemaps. Currently I generate sitemaps in batches of 50k. A situation has come up where I need to change that size to 15k in order to be crawled by one of our licensed services. I haven't been able to find any documentation on whether or not changing the size of my sitemaps(but not the pages included in them) will affect my rankings negatively or my SEO efforts in general. If anyone has any insights or has experienced this with their site please let me know!

Hello Mozers, Our sitemaps were submitted to Google and Bing, and are successfully indexed. Every time pages are added to our store (ecommerce), we re-generate the xml sitemap. My question is: should we be resubmitting the sitemaps every time their content change, or since they were submitted once can we assume that the crawlers will re-download the sitemaps by themselves (I don't like to assume). What are best practices here? Thanks!

We use og (open graph) titles in lieu of meta titles. Is there any downside to using just one. Should we be using both og and meta titles on our page. Appreciate any insight. Himanshu

Want to optimize referral traffic while at same time keep search engines happy and the ads posted. Have a client who advertises  on several classified ad sites around the globe. Which is better (post Panda), having multiple identical urls using canonicals  to redirect juice to original url? For example: www.bluewidgets.com is the original www.bluewidgetsusa.com www.blue-widgets-galore.com Or, should the duplicate pages be directed to original using a 301? Currently using duplicate urls. Am currently not using "nofollow" tags on those pages.

Some time back we implemented the Google recommendation for pagination (the rel="next/prev"). GWMT now reports 17K pages with duplicate title-tags (we have about 1,1m products on our site and about 50m pages indexed in Google) As an example we have properties listed in various states and the category title would be "Properties for Sale in [state-name]". A paginated search page or browsing a category (see also http://searchengineland.com/implementing-pagination-attributes-correctly-for-google-114970) would then include the following: The title for each page is the same - so to avoid the duplicate title-tags issue, I would think one would have the following options: Ignore what Google says Change the canonical to http://www.site.com/property/state.html (which would then only show the first XX results) Append a page number to the title "Properties for Sale in [state-name] | Page XX" Have all paginated pages use noindex,follow - this would then result in no category page being indexed Would you have the canonical point to the individual paginated page or the base page?

Working on a site for a dentist.  They have a long list of services that they want us to flesh out with text.  They provided a bullet list of services, we're trying to get 1 to 2 paragraphs of text for each. Obviously, we're not going to write this off the top of our heads.  We're pulling text from other sources and trying to rework. The question is, how much rephrasing do we have to do to avoid a duplicate content penalty?  Do we make sure there are changes per paragraph, sentence, or phrase? Thanks! Eric

Greetings!  On Dec 1, 2011 in a SEOMoz campaign, two crawl metrics shot up from zero (Nov 17, Nov 24). "Title missing or empty" was 9,676. "Duplicate page content" was 9,678. Whoa!  Content at site has not changed. I checked a sample of web pages and each seems to have a proper TITLE tag. Page content differs as well -- albeit we list electronic part numbers of hard-to-find parts, which look similar. I found a similar post http://www.seomoz.org/q/why-crawl-error-title-missing-or-empty-when-there-is-already-title-and-meta-desciption-in-place . In answer, Sha ran Screaming Frog crawler.  I ran Frog crawler on a few hundred pages.   Titles were found and hash codes were unique.  Hmmm. Site with errors is http://electronics1.usbid.com Small sample of pages with errors: electronics1.usbid.com/catalog_10.html
electronics1.usbid.com/catalog_100.html
electronics1.usbid.com/catalog_1000.html I've tried to reproduce errors yet I cannot. What am I missing please? Thanks kindly, Loren

I've been getting 73 "title missing or empty" warnings from SEOMOZ crawl diagnostic. This is weird as I've installed yoast wordpress seo plugin and all posts do have title and meta description. But why the results here.. can anyone explain what's happening? Thanks!! Here are some of the links that are listed with "title missing, empty". Almost all our blog posts were listed there. http://www.gan4hire.com/blog/2011/are-you-here-for-good/ http://www.gan4hire.com/blog/2011/are-you-socially-awkward/ MaeM3.png TLcD8.png
