How it is hard to find a keyword ?

always search for long tail keyword its easy to rank + you will some with more than 1000 searches monthly

long tail keyword is the most important

it's all a question of your own background, some people find KW research the easiest thing and have trouble with other areas of SEO

there are still TONS of relatively low competition kw's with 1k+ search that are monetizable
though many of the older methods used for ranking for those sites are getting trickier -- the biggest thing is to take action
