Google does not let anyone know the ingredients of their secret sauce so there is no definitive answer to the question ” how many links does it take to get page rank X”. However, everyone loves trying to solve a mystery.
Here’s a chart that tries to approximate the number of inbound links it takes to achieve the desired page rank.
| PR | To Get PR3 | To Get PR4 | To Get PR5 | To Get PR6 | To Get PR7 | To Get PR8 |
| 1 | 555 | 3000 | 17000 | 93000 | 508000 | 2800000 |
| 2 | 101 | 555 | 3000 | 17000 | 93000 | 508000 |
| 3 | 19 | 101 | 555 | 3000 | 17000 | 93000 |
| 4 | 4 | 19 | 101 | 555 | 3000 | 170000 |
| 5 | 1 | 4 | 19 | 101 | 555 | 3000 |
| 6 | 1 | 1 | 4 | 19 | 101 | 555 |
| 7 | 1 | 1 | 1 | 4 | 19 | 101 |
| 8 | 1 | 1 | 1 | 1 | 4 | 19 |
| 9 | 1 | 1 | 1 | 1 | 1 | 4 |
| 10 | 1 | 1 | 1 | 1 | 1 | 1 |
For example: to get a page rank of 5 you would need either 4 inbound links from a page with rank 4 or 3,000 inbound links from pages with rank 1.
