Images and graphics will affect Page rank due to the size of files.

Images have large files depending on the type of image used, which makes it hard for Googlebots to read. Image files are often not recognized by Googlebots and passed over by them. This makes images and graphics bad for Page Rank.

Content: is the name we give to the text part of your site. When this is optimized and of high quality, it will please both your visitors (Google customers) and of course the Googlebots. This will result in higher page rank.

Googlebots are looking for websites, which will give visitors:

Information: content that provides information will give this.

Visitors will love informative articles and keep returning for more. Information will include different aspects of your business or knowledge about products and services.

Interesting: There is all sorts of content about your business that will be interesting to your visitors. always remember to make it useful and relevant to your business.

Has good quality content: This is another key point that Googlebots are looking for. Your content should be of high quality, useful and well written etc. Your content should draw your visitors in and invite them to return again and again.

Your website should have great resources: This will include not only good content but links leading to high quality and informative sites. These will be considered good resources by Googlebots and improve your Page Rank.

Image and graphics as far as Googlebots are concerned do not serve any purpose and as mentioned above are often not read. The best thing to do if you need graphics is not to place them at the top of your website and to keep the files as small as possible. This will ensure that Googlebots find your content and relay all the information accurately about your site back to the Google database.
