updating content , advertise on google adwords , writing 3 article every day , they are effective for getting good position in google then can earn income well from website.
ABSOLUTELY NOT... I can tell you after being Sr. SEO Manager for several years for a site 85% of US citizens know about who spent $3-5MM (Million) per month on PPC with most of that being at Google on Adwords that your Adwords spend has ZERO affect on your organic rankings... None. Link building is still the key to rankings at all of the major engines.
