How long should be your resource box?

Maximizing the effectiveness of your article, you need to have a well written resource box. The resource box is where you get a chance to sell yourself, your business, your offers, and and sometimes your biography.

One problem I think many of us as we post an article and thinking of having a good resource box, and the question is how long should our resource box or bio box be?

2 to 3 lines with anchor text or direct links of course, and another thing even how good your resource box was, you must also have article that has unique and interesting content. and also you must follow article directory guidelines for effective article submission, most articles are being denied because they didn't follow guidelines especially on the resource box part.

It must be only 2 or maximum 4 lines word count should be not more 200 words with spaces .
