Display: none
-
A prominent SEO consultant recently told me that using display:none in the css is still a bad idea. We built a simple drop down menu using widely used jquery techniques and it uses display:none to slideToggle the menu.
Does anyone else think this is a bad idea? If so, how should I change it since just about every jquery drop down I come across uses the slideToggle/display:none.
-
I'd suggest checking that any jquery solution hides stuff with display:none after the page has loaded. Essentially is the content/menu fully visible when you turn javascript off and load the page? (regardless of how horrific the display looks?)
Bear in mind that Google also advises against things like display:none for implementation of things like microformats.

Using display:none is fine. There's JavaScript on the page that will make those items display when the users takes some action on the menu. Google has some way of reading the JavaScript to see what may be displayed, and at this point, I'm sure they're very good at detecting these types of menus. I don't think you can't make a menu like that without using it, and tons of sites use them.
Obviously, you shouldn't use display:none to cloak text on the page, when no user action can get that text to be displayed.

Conventional wisdom says this is a bad idea because its a technique used by black-hats to stuff keywords into their documents. See:
http://www.mattcutts.com/blog/seo-mistakes-unwise-comments/
However, for JQuery and things like menu's and screen reader links, Google appears to know the difference. See:
http://www.google.com/support/forum/p/Webmasters/thread?tid=50f9a4942ac605ec&hl=en
The takeaway is you can use this, and its unlikely to get your site penalized. But be careful that what you're doing is both (a) common practice and (b) couldn't get caught in a spam finding algorithm. If you are in MLM or pharmaceuticals or something that often gets associated with spam, you'll want to avoid using these techniques. If there's no way your site could be considered spam and you're using display:none legitimately, then you'll be safe.

Rich Snippets Inconsistent Display
Hi Folks, We implemented Schema mark up on our hotel details page many months ago now (previously we had a different mark up language, but switched to Schema during a complete page re-design). Its been live for plenty of time now and is being picked up in webmaster tools. http://www.asiarooms.com/en/singapore/singapore/175433-orchard_hotel_singapore.html Even before we switched to Schema we had a very inconsistent display of rich snippet data in the search results and this has continued despite the mark up being implemented correctly. For example, a search in Google Singapore for 'Orchard Hotel Singapore' shows the AsiaRooms.com listing without any rich snippets. You can see that the vast majority of our competitors like Agoda, Booking.com always show rich snippet data (search for 'orchard hotel singapore agoda' for example). I have checked the hotel in the rich snippet testing tool and its marked up correctly such that it should feasibly show the review count and the score. http://www.google.com/webmasters/tools/richsnippets?url=http%3A%2F%2Fwww.asiarooms.com%2Fen%2Fsingapore%2Fsingapore%2F175433-orchard_hotel_singapore.html&html= Whilst Agoda and Booking seem to display rich snippet data on literally EVERY hotel, its very inconsistent for AsiaRooms which is extremely frustrating - feels like some kind of punishment or favouritism. Any ideas why this might be the case and anything I could try to resolve it? Thanks, Ben

How to display the full structure of website on Google serps
I have been searching around but unable to gather information as to how we can control or list top pages of a website on Google's first page , i.e. if we type seomoz in google , we can see the main listing with 6 subdomain listings , which link to Blog , Seo tool , Beginner Seo guide , Learn Seo , Pricing & Plans and login My question is can we control these listings i.e. what to display and what not , and if yes how can we make this type of visibility on first page , by using html or xml sitemaps or theirs something mostly websites are missing. Cause this type of data is coming up for very less websites and mostly websites are with single urls. c43Ki.jpg

Will links to www and none www result in penalty?
Hello all, Normally i redirect my www to none www to avoid the potential of duplicate content and as its typically something that is done in SEO. I don't have access to the site of the company I am working for at the moment as everything related to the sites code goes through the web developer. At the moment the site lives at www and none www and one does not redirect to the other. I have been building links (organically as we engage on a few forums and blogs) to the www as that is how it is linked internally already and how links from the job boards we post on link. We do however have some natural none www links and my concern is that since the site isn't redirected that it is being penalised or could become penalised because of this. I imagine that it isn't a serious penalty if one at all but I would rather know so I can try and get it sorted as fast as possible. Thanks.

Why does GWT fine duplicate descriptions where none exist?
On my website, www.heartspm.com, I have been gradually changing over local information to remove near duplicate content. I created templates to create near duplicates for regions (coastal, inland, valley, etc. Then I also have been gradually creating unique pages for each city, such as Poway, Santa Monica, etc. Either way, I have this component of the website built on a list of cities with SEO information unique to each one pulling in template information. Now to my question: I am getting most of these pages coming up with GWT duplicate meta description information even though the descriptions are quite different between city to city. I am viewing the source page generated as well as the descriptions that are displayed by Google on the search engine. These descriptions do not appear to duplicate to me. So why the error?

Setting preferred domain as www or none www
Way back before panda I used to rank for certain keywords pretty well. Of course like many others after panda I lost some of those rankings. I have been getting better since then so its not that bad. I was poking around in Google Webmaster Tools and I noticed something which I need some clarification in. History my site freescrabbledictionary.com used to be indexed as a none www. Then some time ago I can't remember when I set it to www. Tonight I was looking through my webmaster tools and I noticed something that did not make sense to me. In my content keywords section for the none www my list is as follows Content Keywords <form action="https://www.google.com/webmasters/tools/keywords-list?hl=en&siteUrl=http://freescrabbledictionary.com/" method="GET"> Keyword Significance 1. scrabble 2. words (2 variants) 3. dictionary 4. cheat 5. finder 6. friends 7. maker (2 variants) 8. noun 9. letter (2 variants) 10. hasbro 11. mattel 12. spear 13. found (2 variants) 14. sowpods 15. freescrabbledictionary 16. builder 17. affiliated 18. search 19. solver 20. lists </form> Then I looked at my www lists and its Content Keywords <form action="https://www.google.com/webmasters/tools/keywords-list?hl=en&siteUrl=http://www.freescrabbledictionary.com/" method="GET"> Keyword Significance 1. words (3 variants) 2. scrabble (2 variants) 3. letter (4 variants) 4. points 5. cheat (3 variants) 6. friends (2 variants) 7. finder (2 variants) 8. anagram (2 variants) 9. dictionary 10. tool (2 variants) 11. hasbro 12. mattel 13. spear 14. game (4 variants) 15. mobile 16. affiliated (3 variants) 17. berkshire 18. canada 19. calculations (5 variants) 20. coming (4 variants) </form> My none www version has the order (especially the first 5 keywords) that I want, my www version is no were near it.
