I'm like embaressed to ask such a noob question like this, not only do I have around 43 websites but I've been an SEO expert since November 2007. I've done every single white hat method except article submissions and press releases. There has been article submissions here and there but nothing near to effect SEO ranks. I'm a stock broker so I have a stock website and I've done hard marketing and stick to my weekly 200, 200, 200 rule which is 200 blog comments using deeplinks, 200 social bookmarking submissions and 200 trackbacks, pings. I found out that submitting your tags pages using wordpress; you get good SERPs with google. I'm ranked #1 for every company I've wrote a blog post about . I rank for keywords like "Aig stock tips" "Bac stock tips" and pretty much every company listed on my site with their symbol following stock tips. I have a very, very effective white-hat SEO strategy. I'd just like to put the extra kick into the SERP's cause I'm aiming for the word "stock tips" . Question is ... Will it hurt my SERP's or de-rank me from google if I submit some of the article from my website to ezine articles? I don't want google to ban me for duplicate content. Part of my SEO success is from writing 100 % content, tags, description for all my pages, submissions, comments, titles. Oh and how effective is Article submissions? Does it make a difference? Don't lie or BS or say you know when you don't know for sure or guessing that you think you know. How could you even guess to think that you know your guessing? LMFAO. I know most other answers about SEO and I can't answer this question, once again I feel like a noob for asking this.
