6 Visual Optimization Mistakes
Make Your Visual Media Search Engine Friendly
Use JavaScript Wisely
Using JavaScript to display content can add great features to your website. However, in the long run, it can also make content harder to be reached by search engines. When using JavaScript do so wisely and keep the code clean.
Make Use of Image <alt> Attribute
Text only websites are typically dull and image based websites are unrecognizable to search engines. Find a good balance between related content and images, and always make use of the image <alt> attribute. However do not keyword stuff the <alt> attribute as this will hurt your rankings.
Provide Additional Content with Podcast and Videos
Podcast and videos are great for users as well as lowering your bounce rate. However, without any additional content, they are rendered as useless for search engines. I recommend providing a transcript or any additional content along with your podcast and videos.
Stay Away From Image Links
Search engines feed off of links and hyperlink text plays an important role in determining rankings. As search engines cannot read images, using them as links is typically a bad idea, especially if doing so within the main navigation. If you cannot get around using image links be sure to use an <alt> attribute within the image.
Do Not Use Frames
Frames are extremely bad for SEO and are also an extremely outdated method of layout, so use them only if absolutely needed. A good alternative method to frames is PHP and the ability to include files.
Do Not Use Flash
As of yet search engines are unable to index flash based websites, thus any content used within a flash based website is unknown to search engines. If you must, you may use flash elements within a website, however not for laying out any links or content. If using any flash provide alternative content as well.

Thanks for information and links! I typically do not do a lot of work in Flash and was unaware Google had officially announced that they were indexing Flash sites, my apologies. I do ask though, what if your Flash website is pulling content from a database, will Google index it then? Or, what if your content is buried within a sub page and your flash site is not using a unique URL for each page – how does Google link to it?
While Google may be able to index Flash I still think there are quite a bit of pitfalls to anyone serious about SEO.

You are correct, thank you for pointing this out. I have edited the text to reflect this.
Re: Do Not Use Flash
Whilst I agree that Flash shuold be used judicously, Google is able to index flash content.

Being pedantic, alt isn’t a tag, it’s an attribute of a tag…
Great article Shay,
One correction when it comes to Flash, as of June 18th Google does index Flash content, even linked content.
Have a look at Google’s webmaster blog, to read the whole announcement.
