Welcome to the Q&A Forum

I like around 20%, but probably best look at the niche average.  Or look at the most natural link profile in that niche.

A good idea is to get the link profiles of all your competitors on page 1.  Then break all their links down by type, you will then get a good idea of what it takes to rank in that niche.  If you aren't hot on excel, you could try cognitiveseo - they give this type of link profile breakdown... very useful

A massive part of SEO if getting domain authority, this is what you would split by having different sites...everything would get diluted.

Most people don't understand social media, even people employed as social media managers!!  If you are serious about social you would do well to outsource to someone who knows their s*#£$.

Nice find...

The head section of this page has:

NAME="ROBOTS" CONTENT="NOINDEX">

Which is why this page is not indexed by Google too.

Yer just code it so a html link sites outsite

I'd just get an infographic designer to do, otherwise it will turn out crap.  PM me if you need one...

You could also look at cognitiveSEO.

I wouldn't worry about them because they will be impossible to undo.

So you are saying you have been only building links for 3 months, but looking at OSE the Canon TSi page has 425 linking domains and canon 7D 751 linking domains??   This is way too many for that time frame IMHO.  I would say you have tripped a filter.  Wait 60 days and see if it comes back up... it should do.

Is that one of Distilled's link  building packages?  

You missed the 3rd option, follow them from a specially created bot account

If you self host the videos on your own site, its unlikely Google will actually display them in the SERPs for your keywords.

You used to be able to map a domain onto a high PR site and it would mimic the PR after a while.

Why don't you just block the other pages, so you only have your standard canonical page being indexed?  You can then cloak the content by IP, but remember Googlebot always crawls from the US so make sure it is seeing the standard version.

Just do internal redirects on your affiliate links  e.g. yoursite/go/affsite  redirect to aff site.

You then block the /go/ folder in robots.txt

Hope that helps!!

"...it is slow and tedious"  I'm affraid that's link building for you.  The longer and harder a link is to get, the better it is likely to be.

There are lots of different tools you can use to find places... here is one http://www.youtube.com/watch?v=HwraahDiDm8

I'd do 5-10

Yes just looking at an email in webmaster tools right now

Agree with @Daniel  - G has also lowered the value passed by such 301s. Once had a client who had 50+ redirected sites to his main site, I had to tell him to stop!
