One thing that can confuse search engine spiders are sloppy headers on your website. It is just so easy to miss this one little thing especially if you are using a site builder on a host like freeservers.com, bravenet.com or homestead.com. What happens is that while you are building the website you may be asked to save the website as something when you go to work on a new content page. However you may forget the non-visible header area of a page when saving it causing search engines to ignore the page because they see it as non-functioning or duplicate content. Dont think this problem is limited just to site builders. It is also very easy to forget about your headers for web pages while saving your site in do-it-yourself site software such as Dreamweaver.
The ultimate result of this type of sloppiness is a site that has a title that is the same on every page. The meta tags on every page are also identical. Only the visible content is different. To avoid this stick to a regime of developing your new content on the page and making a note to yourself to always develop the title for the new content page before moving onto the next one. This way you dont forget to practice...
