When you obtain one-way links as well as immediate visitors, you should properly address your document for it to be optimized well. Otherwise, the publication address for your target article may be confused and lost along the way. Extending your document is usually republished. There is a tendency that the WordAI can lose the article you are writing.
Anyone can do this, all you need is a computer and the ability to string a sentence together. You can write original articles and submit them to article directories and get paid. You have to apply to these sites and may or may not get turned down. If you should happen to get turned down then just keep plugging away until you find someone to "hire" you.
