Google does not regulate the traffic to the sites
Google does not limit traffic to the websites and does not establish quotas for a visit. About this said the representative of the search John Mueller during one of the last hangouts for webmasters.
A few years ago among the foreign SEOs think that Google adjusts the traffic to the sites. The supporters of this idea believe that the search engine allocates each resource a certain number of visits per day. After the limit is reached, Google redirects traffic to another site that he also was visiting. Many SEO experts believe this concept is completely ridiculous, others justified.
Last month the question on the traffic throttling has been actively discussed on the forum Webmaster World. Yesterday a famous SEO analyst Glenn Gabe posted on Twitter a link to a recording of the hangout for webmasters, in which John Mueller denied the idea of quotas:
"I occasionally see an opinion that Google has a quota for websites, but it's not. We do not say that today the site must have 5 thousand visitors, tomorrow – 7 thousand. Search doesn't work. Users "do not work". Sometimes people are looking for more and more, sometimes less. Sometimes your website more relevant, sometimes less. Quota no."Listen to Muller's response, starting with a mark of 33:48 in the video below:
