Google owns more than 7,000 websites and is run by hundreds of product and marketing teams around the world. For these sites, seo is also at the heart of their traffic sources. Although the proportion of search traffic is declining in recent years, it still accounts for about half of the total traffic of the website, and is still the largest source.

Search algorithm treats all websites equally

google search algorithms treat their websites and other websites equally, without special care. The operations team must also comply with google’s published website quality guidelines.

Unlike the outside world, google’s internal employees don’t necessarily know google’s search algorithms. The teams of hundreds of operating websites, like ordinary seos, probably don’t know much about algorithms. Google’s own website has been repeatedly penalized by its own algorithms, and even to be penalized, it needs to submit an application for review in google search console, just like other webmasters.

Official representatives of google’s communication with the seo community may not fully understand the search algorithm. Just a few days ago, in recent years, instead of matt cutts, gary illyes, who attended seo industry conferences around the world, just discovered that google no longer uses the rel=prev/next tag, and google’s online help documents, external communication and answering questions in the past few years. This label is recommended again and again. The team that the search algorithm was responsible for grabbed the label a few years ago, and the others did not know. Gary illyes probably discovered this incident by chance, so he removed the relevant help documentation. Some SEO noticed that the document was withdrawn, and another google official seo contact, john mu, mentioned in twitter's answer to the question that google didn't use the rel=prev/next tag at all.

This topic has caused a lot of fluctuations in the seo industry these days. Gary illyes and johnmu are very familiar with the algorithm, otherwise there is no way to answer the questions of seo. Even if they don't necessarily know a lot of algorithm details.

Therefore, the team of google's operating website and the average seo are roughly on the same starting line.
