I inspected the source code of competitor and discovered a commented line like this: <!-- KEYWORDS & PHRASES --> Also, further down the page I discovered tons of links with keyword stuffing that were using a foreground colour almost identical to the background colour. What should I be doing?
Report it to Google and if you do not do that also then also they would not get bigger with these techniques in Google
This kinda of strategy is for short time. Google will eventually see this and penalize your competitor.
Google, somehow will know about it and they will give penalties on this sites/blogs or even worse they might be banned..
