You've stumped me there. Maybe its not giving you an accurate count of backlinks, or maybe its counting the www and non-www version of the domain name as 2?

Say you had links coming from example.com/page1.html and example.com/page2.html. You would have 2 external backlinks from one referring domain.

To the best of my knowledge this has no impact on SEO. Googlebot doesn't like it when you hide content, but that only applies to overflow:hidden and display:none as far as I know.

Like Mr. Barth says, 301 redirects occur on the server level, before a page is even served up to the end user, and so presenting an alternate isn't possible this way.

You could use the meta refresh tag, or another server side technology like php or asp to accomplish this. Do this and the link juice is gone, though. To address that issue, you should use a rel canonical tag to tell robots that the buyers site is the canonical version of your domain, and assign all value there.

EDIT: To be clear, I'm recommending you both forward the request AND use rel canonical.

This feature is a little confusing. Alt text is an attribute of the img tag in HTML, so this would normally be outside the realm of photoshop. To use the photoshop alt text feature, you need to export the HTML for the image when you're saving it.

See http://www.adobe.com/accessibility/products/photoshop/images.html under the heading "Exporting HTML from photoshop".

Once you've exported the html, you can paste it into your html document. To me, its all much more complicated than simply typing out < img src="myimage.jpg" alt="My alt text" / > but that may be due to my technical background.

Blogs are a well understood format for delivering new content. There isn't anything inherently special about having a blog, you still need to do the basic on page SEO to optimize your posts, and you'll still want to do link building to generate authority.

In very general terms, blogs are recommended for SEO because it encourages site owners to publish fresh content often, and in a format that most web users know how to share with each other. Its up to you to create the killer content that gets the links.

I assume you're talking about a wordpress site?

Tag, author, and archive pages represent a possibility for duplicate content, and so most people recommend noindexing them. You can do that with the popular SEO plugins, like All-in-one SEO.

Generally you want more pages indexed, but only if they're quality and not duplicating existing content. Each additional indexed page represents another chance for people to find your site.

To clarify: Alt attributes should not be used in anchor tags, but titles can be. For a full list of anchor tag attributes see: http://www.w3schools.com/tags/tag_a.asp

The keywords meta tag is deprecated and not used by any of the major search engines, so don't even worry about that.

As for a general strategy you should focus on a keyword or two for each page and optimize for that. When you link internally in your site, use the keywords your optimizing for in the anchor text. When acquiring external links try to do this as much as possible. Don't cannibalize yourself by trying to optimize for the same keyword across all your pages.

I wouldn't worry about making landing pages in order to get them ranked - thats what your main pages are for. Use landing pages to test out what converts best with A/B testing, and as end points for your PPC campaigns.
