Hello , Well i have a tech blog and i m updating daily with latest technology news about mobile , laptop, tablet, android, iphone...etc And i write 250-300 words news .. So would like to know is there any problem if i write such kind of information ? I m very afraid of Google adsense..
You are doing write things. No need to worry for any thing. keep it on. These days it is very interesting topic and new generation loves to read about mobile, i phone applications, i pad etc.
Sounds like you are on the right track. Just make sure you don't stuff your keywords too much into the articles.
250-300 word news are adequate for Google adsense. However, don't get too strict on word count. Any variation is welcome as long as is natural and justified by content.
The amount of words for your post is good, make sure you put in the right amount of keywords too and not stuff them in the content.
