Can you give me an idea about a standard blogpost, an entry which google will love most every time you'll create an entry with such format? if you also wanted a kind of ads that will appear in your adsense box, how will you do it?
i have once sold a blogpost from someone and it gets annoying that all the ads displayed in my homepage was about his entry. and its just one post that affects everything no matter what entry i have posted in it, his ads still appear. what should i do? should i erase his entry
A standard blog post should be keyword oriented (not too much of keywords though). It's always better if you can give it in points that writing whole story in text junk. People hate to read paragraphs.
That is why you should always take care to make only relevant posts ot your niche. Any ways to solve your problem, you can use section targeting in Adsense. You can place the content you don't want o be taken into consideration in between <!-- google_ad_section_start(weight=ignore) --> and <!-- google_ad_section_end --> You can know more about it here https://www.google.com/adsense/support/bin/answer.py?hl=en&answer=23168
One with a good title, paragraphs, good written english if your blog is in english, unique written content, also use meta keywords and description. Please the reader first and pleasing google comes naturally. You do know that google is not human right? it does not wish to be pleased, the people behind google merely ask that you use common sense.
How do i know that i have a good title for instance i have an articlce? Lets take away that 'good english' that you mentioned as for now. i'm not really good at it. I also write my contents on my own and so i hope its unique.
Well for example a title that makes the reader want to look further. Ok how about acceptable english then? as long as the reader can make sense of the article. You maybe are quite good, if you are writing your own articles then thats excellent.
