What is the primary difference between site-wide blocking and ad category blocking in AdSense?

The primary difference between site-wide blocking and ad category blocking in AdSense lies in the scope of control they provide over the ads displayed on a website. Site-wide blocking allows a publisher to prevent ads from specific websites or advertisers from appearing on their entire site. This gives the publisher complete control over which advertisers can show ads on their content. Ad category blocking, on the other hand, allows a publisher to block entire categories of ads, such as sensitive categories like 'politics' or 'religion', or general categories like 'automotive' or 'real estate', from appearing on their site. This allows the publisher to filter out types of ads that may not be relevant or appropriate for their audience or brand. Site-wide blocking is very specific, targeting individual advertisers, whereas ad category blocking is broader, targeting entire classes of ads. Both are tools for controlling ad content, but they operate at different levels of granularity.
