Magento Go allows site owners to place a block in the sidebar. If the Magento theme supports sidebars on both sides, just like the default theme, then you can place the content block in either of the two sidebars. By slightly tweaking the codes, you can position the block and control its position in relation to other blocks in the sidebar.
If you are unable to place the Magento block correctly, then either follow the above steps once again carefully or Request a Quote with us. Our Magento team of developers will assist you in placing the blocks in your desired sidebar.
