OK, this is a immersive subject and I want to emphasise it’s not clear cut. But here is what I know in my research at the Backlinks clinic:
Authority – simplified
The more authority your site has the higher you will rank on Google. Authority means that people trust you and your information. The good news is that authorities trusted by humans are also trusted by Google. A good illustration is the .edu and .gov suffixes. These domains imply they are credible sources of information and it’s an established fact that in the eyes of Google backlinks from these domains to your web pages will send authority to your web pages. Another shining example is Wikipedia as the entries here are largely contributed to by tribes of people as opposed to a single person.
So it follows that authority is significantly influenced by the source of your backlinks and if authoritative sites link to your site then you inherit their authority and in the eyes of Google you become more authoritative and hence the trust in your site by Google increases.
How Google determines what is and isn’t authoritative is undisclosed for good reason and aligns with Google’s thinking of “Do no evil”. The last thing the Internet needs is someone exploiting the mechanisms that Google untilzes in its efforts to try and bring some order to probably the most significant technological resource of this period in history.
Backlinking methods you should avoid
In the same vein it’s worth my while stating some obvious sources and methods of building backlinks that Google not only dislikes but appears to be moving aggressively to ‘classify’ as negative authorities. In no particular order of severity, the common examples are:
- Paid backlinks – web pages where individuals purchase and sell backlinks
- Comment spam – entries that have links on blog pages that are just not associated to the main theme.
- Low quality and *duplicate content – ‘scraped’ or copied
- Rapid backlink growth – there are a myriad of ways that this is achievable, Google isn’t stupid. Any sudden rise in the number of backlinks is going to show up on Google’s monitoring systems, specifically if it’s a recently registered domain.
- Backlinks from unscrupulous 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 reputable news portals appear 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 monitoring this, only as a portion of of the results I am seeing go against the consistent behaviors I normally expect to see. More on this is in a future post….
