Quality links to your site
So who has the time to link to a website, and why would you want to link to a website?
I'm pretty altruistic when it comes to linking and I don't slot in a no-follow attribute either, but, the site I'm linking to has to have quality content - so far this is exactly what Google say in their article about quality content, but I'm not sure if the nature of the web is altruistic on the whole. Yes between friends sharing stuff on Facebook and Twitter, but what if you've a pretty mundane business, it's going to be mighty difficult to get links from other sites no matter how much humour you try to conjure up on your site.
Every day as a SEO/ SEM you get requests for reciprocal links, but we know they're rubbish. Google tells us some Directories are good others bad - yes you've got to be a little naive to believe that by spending £20 on 350 links you'll suddenly reach the dizzy heights of a #1 spot in Google search, but carrying out the link building manually - is it any better, probably not as the Google bot never goes past the 1st page of most directory categories.
So is it also a little of naive Google to believe we live in this ideal world where people will literally rate sites (by adding a link), positively if they've had a good experience or with 'page speed' coming in, won't they just realise if a visitor hasn't the patience to wait 10 seconds (Website Response Times - Jacob Nielsen, there goes my altruism again) surely they haven't the time to (in most cases) go back to their site and add a link!
