Google's biggest source of revenue is advertising, and the biggest source of revenue from advertising is search recommendations, and the core of search recommendations is the ranking of relevant web pages.

The reason for PPC is because the attention of users is limited, just like wealth, the smallest number of top-level pages will get more than 95% of the attention of users.

The number of searches and the number of pages read by ordinary users every day are limited, and how to push the most effective ads in the limited number of pages is the core problem of the recommendation advertising algorithm.

All advertisers know that at least seventy or eighty percent of the advertising money they pay is wasted.

But the problem is that no one knows which two or three percent of the special ones have played a role.

Not a penny less than what should be paid.

For Google, how to better plan and distribute these display interfaces is a profitable way to generate revenue.

To take an extreme example, if Google can push ads to everyone, they are exactly what they need and will click.

Then the theoretical upper limit of the recommended ad is achieved, and all the money is made with the smallest impressions.

It's a pity that most manufacturers can't do this proportion at present, and even Google, it's only about two percent.

The purpose of the "Mobile Optimization Strategy" and "Fred Algorithm" provided by Meng Fanqi is to further eliminate those web pages that look inconvenient on mobile phones and all kinds of spam websites.

As long as I exclude more spam, the rest of the content is more likely to be clicked.

Combined with the language AI model, it is done by additive, by better understanding the user's search intent, to provide more relevant results.

As a result, users see a more relevant interface after each search, fewer dump sites, and more ad clicks.

Based on the experience of the original timeline, Meng Fanqi estimated that after the three axes were wielded, the improvement of the effect should start at 20%.

The more Xi Xiaohu listened to the details of the idea, the more interesting he felt, he originally only planned to chat for a few minutes, but before he knew it, close to an hour had passed.

The two of them did not specifically look for a conference room, but found a sofa near the reception at the front desk and talked eloquently.

Many Google employees who passed by at work were quite surprised after seeing it.

Xi Xiaohu's rank is still quite high, and many employees of Google Shanghai rarely have direct contact with him.

A handful of interns didn't even meet the big guy much.

"Alas! Zhou Huan, Chen Ash, just right. Come here. Xi Xiaohu caught a glimpse of two passing Google employees and called them over directly.

As soon as Zhou Huan and Chen Ash came back from making coffee, they saw the big leader chatting with a young man who looked like a student, and they were very curious.

Because Baidu immediately announced the product, Li Yanhong personally did two promotions, and many people knew Meng Fanqi.

On Google's side, Jeff and Hinton did not affect too many unrelated people, except for the introduction inside Google's brain.

Therefore, Zhou Huan and Chen Gray, who focused on the advertising part, did not know the composition of Meng Fanqi at the moment, seeing that he was so young and able to talk and laugh with the big leaders, they thought that he was an intern who came in through a relationship.

"Leader! Don't worry, the two of us will definitely take care of him! As soon as Xi Xiaohu introduced a name, Zhou Huan didn't wait for Xi Xiaohu to give orders, so he took the lead in expressing his position.

"Okay, okay, you guys prepare the local relevant accounts, permissions and tools, he is mainly here to do the work of our search and recommendation part during this time." Zhou Huan and Chen Ash are both veteran engineers with some qualifications in the group, who are technically measured and know how to lead people.

Xi Xiaohu felt that although Meng Fanqi's ideas were quite thorough and excellent, it was the first time to enter the advertising algorithm department to write core content.

If nothing else, it takes a lot of time to get familiar with these existing things.

After all, there is still a difference between understanding the principle and understanding the code and being able to develop and create it by yourself.

He could see that the two had misunderstood Meng Fanqi's identity, but he didn't mean to remind them.

First, Meng Fanqi is indeed like an intern and needs to be familiar with a lot of content.

The second reason is that Zhou Huan and Chen Ash are always a little clever on weekdays, and they often have low eyes, and they cause him a little trouble at every turn.

The two of them have made many meritorious contributions before, and he doesn't have much to say.

"Humph! This time, I will let you have a good look at what it means to have someone outside. Watching Meng Fanqi follow the two to the work area, Xi Xiaohu grinned and sneered.

"How old is the little brother? Where did you read it? On the way to the workstation, Zhou Huan began to ask.

"I'm in my early twenties, and I'm in my senior year next year." Meng Fanqi told the truth.

"Good!" Zhou Huan applauded loudly in his heart, and when he saw Meng Fanqi chatting with the leader, he had already made a bet with Chen Ash in private.

The bet is whether Meng Fanqi is an intern, and now Zhou Huan thinks he has won a big victory.

Zhou Huan continued to walk forward with the two, while putting his left hand behind his back, hooking his four fingers, signaling Chen Ash to be willing to gamble and lose.

Chen Ash rolled his eyes, took out his mobile phone and transferred a red envelope of 200 yuan to Zhou Huan.

"Your internal account has already been handled?" Soon after Zhou Huan saw Meng Fanqi sit down, he logged in to Google's internal account with ease, and suddenly felt a little bad.

"Yes, now I mainly need you to introduce me a little bit about the process of launching the advertising algorithm, and I need to get permission to all the relevant data and scripts in this process."

Meng Fanqi probably knows that this test process is usually offline first on different scales, and then partially online, and then the test will be implemented to the whole world after the test is normal.

Backups are kept at each stage so that problems can be rolled back at any time.

"I'm super, Google Brain?" When Zhou Huan assigned permissions, he looked at Meng Fanqi's email suffix and was startled.

At this time, although Google Brain was not yet the giant team that came later, it was still a somewhat famous department due to the leadership of star engineer Jeff.

The corners of Chen Gray's mouth hooked, and he raised his chin at Zhou Huan proudly, according to the rules, if you don't understand the situation, you will reach out and ask for money first, which will be doubled.

Zhou Huan shouted that he had made a mistake, so he had to reluctantly retreat 200 and turn 400 over.

Meng Fanqi glanced sideways slightly, probably understanding what these two guys were doing.

Capitalist companies are just not wolfish enough to spend their minds on this kind of some and no all day long.

Meng Fanqi, who took over the permission, was the first to implement the Fred algorithm.

The part involving AI requires a period of preparation and training, while the method of mobile optimization, short-term testing may not be obvious enough, and the effect will be better later in 14 years.

But Fred's algorithm is very amazing in its ability to filter spam sites on the Internet.

After the algorithm is launched, it may be that nearly 7% of the current websites will be greatly affected.
