The link between backlinks and Google authority
21 10 2009Hmmmm, this is a big subject and I need to emphasise it’s not clear cut. But here is what I have learned in my work at the Backlinks clinic:
Authority - basics
The more authority your site has the higher you will rank on Google. Authority means that searchers trust you and your information. The good news is that authorities trusted by people are also recognised as trustworthy by Google. A good illustration is the .edu and .gov domain extensions. These suffixes imply they are trustworthy sources of content and it’s an established fact that as far as Google is concerned backlinks from these web addresses to your web pages will “pass on” authority to your site. Another good example is Wikipedia as the contents here are largely added by by tribes of people as opposed to a single source.
So it follows that authority is largely influenced by the source of your backlinks and if authoritative content link to your web pages then you receive their apparent trust and in the eyes of Google you become more authoritative and hence the trust in your web pages by Google increases.
How Google pronounces what is and isn’t authoritative is confidential for solid reasons and falls in line with Google’s thinking of “Do no evil”. The last thing the web needs is someone exploiting the mechanisms that Google uses in its efforts to try and regulate probably the most important technological resource of this period in history.
How not to get Backlinks
In the same vein it’s valuable to state some common sources and methods of acquiring backlinks that Google not only disapproves of but appears to be acting to ‘classify’ as illegitimate authorities. In no particular order of merit, the prime examples are:
- Paid backlinks – web sites where people buy and sell backlinks
- Comment spam – entries that contain links on web sites that are just not related to the main content.
- Low quality and *duplicate content – ‘scraped’ or otherwise
- Unnatural growth – there are plenty of ways that this is achievable, Google isn’t dumb. Any sudden rise in the number of backlinks is going to register on Google’s monitoring systems, specifically if it’s a recently registered domain.
- Backlinks from bad reputation web pages – these are particularly nasty as you are guilty by association - need I say more.
*There is another factor where I may be on dodgy ground, but large press portals seem to get a lot of authority and I have definitely discovered significant numbers of the same content over and over again on different web sites with no penalties, I am still looking at this, only as some of the results I am seeing defy the consistent behaviors I normally expect to see. More on this is in a future post….
