Prior to the Yahoo agreement, Yahoo was one of the biggest names in the world of search engines, providing web users with access to a wide range of online services and products. However, things began to change for Yahoo in the early 2000s, as they watched Google take over the search engine market and dominate the online advertising space.

Before the Yahoo agreement, Yahoo had a distinctive approach to search engine optimization (SEO). They aimed to create a user-friendly search experience by indexing and organizing web pages on the basis of their content, rather than on their link popularity or on their placement on the web. Yahoo believed that by doing this, they could provide their users with access to high-quality content that was relevant to their searches.

However, this approach to SEO began to falter as Google emerged as the dominant search engine in the mid-2000s. Google`s algorithm, which placed great emphasis on link popularity and other metrics of authority, proved highly effective in providing users with the most relevant and useful search results.

As a result, Yahoo began to lose ground to Google in the search engine market, and they struggled to stay competitive in the online advertising space. In an effort to turn things around, Yahoo signed an agreement with Google in 2008 to outsource their search engine advertising business to Google.

The Yahoo agreement meant that Yahoo would use Google`s AdSense platform to display ads on its websites and search results pages, and that Google would pay Yahoo a share of the revenue generated from these ads. This was seen as a significant move for Yahoo, as it allowed them to tap into Google`s vast advertising network and reach new audiences.

However, the Yahoo agreement also raised concerns among industry watchdogs over issues of competition and antitrust. Many felt that the deal was anti-competitive, as it effectively gave Google control over a significant portion of the online advertising market.

In the end, the Yahoo agreement was short-lived, as it was eventually blocked by the US Department of Justice due to concerns over antitrust violations. Despite this setback, Yahoo went on to become a major player in the online advertising space, and they continue to provide web users with access to a wide range of online services and products.
