假设有一个网站, initially有100个-page,每个 page有10个 links pointing to it、Now, let's say the website undergoes optimization, and after optimization, each page now has 20 links pointing to it、We need to calculate the total number of links pointing to the website before and after optimization.
Before optimization:
Each page has 10 links pointing to it.
There are 100 pages.
Therefore, the total number of links pointing to the website is \(100 \times 10 = 1000\).
After optimization:
Each page has 20 links pointing to it.
There are 100 pages.
Therefore, the total number of links pointing to the website is \(100 \times 20 = 2000\).
The increase in the total number of links pointing to the website after optimization is \(2000 1000 = 1000\).
Thus, the total number of links pointing to the website after optimization is \(\boxed{2000}\).
