Google is the largest site in the world, and definitely the largest search engine, and so they are the most important when talking about authority.
A site will only gain authority by being a good source of information. It has to be a really popular, trusted, well made site, or it won’t get to the point that it has real serious authority.
Google does have algorithms which you can fool to a certain extent, but it’s only when big authority sites link to yours without you even asking them to from pages that are PR 5 or higher that you really get a lot of authority.
I wrote this article about how to make an authority site, and it explains that you not only need back links from relevant, high quality, expert pages, but you also need to link out to these sort of sites as sources.
It is perhaps just as important that I link out to the Wikipedia page on search engine optimization as it is to link to this page I just found in that same search.
I found this article by SEO Chat which explains how to follow the Wikipedia guidelines to the letter so that you can get a legitimate back link from Wikipedia.
Those things are like gold, so I’m not sure if it’s going to really work for my site, but I’d like to give it a try, and see if I can make a site that they would consider to be a trusted resource that can be verified by authority sources.
Different Ways To Get Authority LInks
I usually just write a few blog posts like this one on my different blogs, and then write some articles on Ezine, Go Articles, Squidoo, Hub Pages, Knoji, Helium, Yahoo Voices, and if you’re in the US, eHow, Examiner, Guardian, and Suite 101.
It’s not easy to get published on a lot of those sites, so you might want to try writing on your own blogs like a Typepad blog or a free Weebly blog, (be careful with them, they can ban you for anything they want, and they do), WordPress.com and Blogger, maybe blog.com and Wix and Tumblr.
As you can see, I just named more sites than you could write an article on in one day, or even in a week, and once you’ve done that, you can go back to each of the pages that directly link to the site, and make links from all the other sites to that page.
This is how you build a link pyramid of solid links, because what you want is a few really high quality, high page rank, high authority links pointing to your site, and they mostly get that way because they have links pointing at them.
This is a standard SEO practice, building a link pyramid out of solid, relevant, well written, long, high quality authority relevant pages that also link out to authority sites as well as your own.
That’s going to be the formula to follow, regardless of future Google algorithm updates. You can count on the fact that Google will be trying harder to maintain quality and avoid spam pages being made.
