We’ve talked about how the quality of a site has a huge impact on SEO – how a poorly coded, broken website is bad for rankings. On the other extreme, you can have a site that looks great visually but isn’t SEO-friendly. Websites today like to use Flash and be very image-heavy because it appeals to users, but web developers forget that Google “reads” websites through text. Meaning if your site is full of images but lacks corresponding alt-text (the text that shows up when you hover your cursor over an image), Google may not be able to read and properly index your website. In other words – your site will look amazing, but Google will have no idea it exists.
This article talks about how to present web information correctly so it can be properly “read” and therefore found by search engines.
