I found matt cutts video which says that keyword rich domains are being devalued.

I would recommend doing more brand awareness exercises rather than switching domain names for a more keyword rich domain.

I am not 100% sure about this, but this is the normal way of consideration. Normally, Google also looks at which data center the user has been querying and based on that it decided the location. It tries its best to give you the location accurately, but sometimes, the mechanism fails, therefore the not set comes in.

I would suggest that depending on the number of pages, you can either do a htaccess based redirection or an apache mod redirect.

Here is an article which could help you.

You may want to see how your website cache for your homepage looks like on Google. Maybe its reading the wrong header everytime. My suggestion would be to check that 1st. If it shows fine, I dont think it will hurt your rankings as such. If you have rel=caononical in place correctly, you would be fine. It would be worthy to identify your pages where you want rankings and based on that, you could diagnose.

I dont think that there are legitimate ways to influence suggest for popular keywords. I have noticed one thing though: Popularity of a particular term leads to its inclusion in the suggest list. Example: I ran an awareness/social campaign to save our historical monuments from vandalism by making a website where people could scribble whatever they want.

That campaign went off really well with retweets and shares among good influencial folks. It got shared on bookmarking websites as well. Suddenly, I started seeing a keyword "responsible travel" coming up on suggestions. But as the momentum died, we lost that preference. Maybe the QDF algorithm kicked that keyword out?

Shwan,

I have noticed that when you have a long URL structure with multiple folders, Google tends to lose "interest" in your deep pages.

Let me give you an example: If you have a domain called www.website.com and you have a category called gemstones. In gemstones, you have diamond as a subcategory and a solitaire as a page.

If you consider your homepage to have an importance of 1, you would not have a category page which also has an importance of greater than or equal to 1. So, your category page gets a page weight value...lets say 0.9. Now, your subcategory page is treated that same way and you give it a page weight of say 0.8. Now, your solitaire page gets a value less than 0.8. Now, if you cut out one or more levels in your URL, you have a better chance of assigning of a higher value to your page.

Now, coming to your question. Breadcrumbs are essentially meant to help your users navigate better. So, your website hiearchy (the folders, sub folders or categories, sub categories) should reflect in your breadcrumb.

So, keep your URLs short, but keep your breadcrumbs like your website flow.

I got an interesting post from one of the bloggers: SEJ shared this on facebook.

Based on the version you have on your server, these documents would be helpful:

http://httpd.apache.org/docs/2.0/mod/mod_rewrite.html

http://httpd.apache.org/docs/current/mod/mod_rewrite.html

Please note: this is not something you would like to do unless you know Apache confuration yourself and you know the codes and its logic.

Domain name change is a very tough decision and changing domain name to accommodate keywords wouldnt work to bump up rankings.

I would do a deep analysis of the website and do some better interlinking coupled with great inbound marketing. Maybe a viral video or something as well...

Changing domain solve your problem. Remember what happened to meta keywords?
