Non-PageRank Factor Threshold

Having written about the difference between PageRank and other factors, and how PageRank is harder to get, it should now be clear that whilst we could use many methods to get good rankings, there is a threshold which defines when high PageRank is worth striving for and when it is not.

With ranking factors other than PageRank, there is a score beyond which the slow down in the rate that any factor adds to this score is so insignificant that it is not worthwhile. This is the Non-PageRank Factor Threshold. To illustrate this,
let?s put an example figure on this of 1000.

If we have a query where the results are Page A and Page B, then Page A and B have scores for that query which are the total scores for all ranking factors (including PageRank). Let's say Page A's score is 900 and page B's score is 500. Obviously Page A will be listed first. These are both below our hypothetical Non-PageRank Factor Threshold, thus without any change in PageRank, it is possible for page B to improve their optimization to beat Page A for this particular query. There are lots of queries like this on Google; they're more commonly thought of as less competitive queries!

Now assume Page A raises its score to 1100. Suddenly page B cannot compete in the SERPs (search engine results pages) without increasing its PageRank. In all probability, page B must also improve for all the other ranking factors, but an increase in PageRank is almost certainly necessary. There are also lots of queries like this on Google, which are more commonly thought of as more competitive queries!

Generally, when querying Google, the group of pages in the SERPs will contain some pages that have a score above the Non-PageRank Factor Threshold, and some that do not.

There is an important point to be made here:

To be competitive you must raise your page's search engine ranking score beyond the Non-PageRank Factor Threshold. To fail to do so means that you can easily be beaten in the search results for your query terms. The quickest way to approach the Non-PageRank Factor Threshold is through "on the page factors", however you cannot move above the Non-PageRank Factor Threshold without PageRank.

The obvious question is what?s the numerical value of the Non-PageRank Factor Threshold, and how much work do you need to do to get past it. The answer is that it has no value; it is a hypothetical line. Google could put a value on it, but that would not help us unless we know what the page's individual scores are. We need only be aware that the threshold exists, and that it gives us information about principles.
