Number of pages in Google index is now over 130 trillion

Google has updated the «How Search Works» page, adding the actual data on the number of indexed pages. At the moment this number exceeds 130 trillion and is still growing.
In March 2013, the number was equal to 30 trillion. In less than 4 years Google has added more than 100 trillion pages into the index.
It should be reminded that now the company is testing a new mobile-first index. This means that in the near future the search algorithms will primarily assess the relevance of a mobile version of the page, and if not, it will use a desktop.

Facebook limits the advertising because of the ethnic ground

Facebook decided to do the revision of the rules of advertising and to limit the use of targeting towards the "ethnic community". From now on companies will not be able to use this option in the ads on the topic of employment, credit services, as well as the sale or rental.
About two weeks ago the possibility of targeting by ethnicity on Facebook was actively critisized. In particular, it was noted that in this way the social network violates the users’ civil rights.
Therefore, Facebook decided to ban this option in the above areas. Bisedes, the company will also make changes in the advertising policy. Under the new rules, the brand companies will not be able to post "discriminatory advertisements."
Changes will take effect by the end of this year. Targeting option to ethnic communities will be moved from the demographic to behavioral category.
When the new system is fully launched, advertisers will receive a warning concerning the violation of service policy when buying the ads.
If the advertiser ignores the warnings and automatic announcements confirmation will not be able to recognize the action of violation, the users themselves will have to inform about the violations.
Later, Facebook will publish some recommendations on how to advertise housing, employment and credit services under the new rules.
