Hello, I released a website 8 days ago and on Google Webmaster Tools I submitted my XML sitemap and it says I have submitted 71 URL's and 36 have been indexed. As far as traffic goes, I've had over 500 impressions in Google Search, 32,000 hits and 458 visits. There is a lot of unique content on the site and it grows everyday and it is aimed at rock music fans so it has a niche. When is a good time to publish AdSense ads on the website?
I am no expert when it comes to google ads but what is mostly important is not the number of ads you have but where you place them, on that note I would say you're ready to implement them now. The only time ads annoy people is when they are all over the place or in annoying places.
You can put it immediately. That's what I do anyway, I don't care if I have only 100 visits per day, some people are bound to click the ads and I won't leave pennies on the table!
Sooner or later won't make a big difference, it will all depends of how much traffic you have. Maybe you'll loss some cents or bucks.
right now I should think, like someone else mentioned, placement of the ads is important, but also having relevant ads is also important
