i am hosting a niche blog about tech. and use adsense on them.
i am researching keyword targeting only US and i am ignoring indian keywords with good search volume
should i target only US keywords or should i look into global search volume also?
Tech is a universal niche. Preferably, you should target the US keywords, but also try to sprinkle a few global keywords in your article for better ad cpc.
Target the whole word as everyone is interested in this niche worldwide. Don't count on just USA traffic.
i am agree with @Derek .
