Form versus Function
Some web developers have a graphic arts background and may pay more attention to how a page looks than considering other issues such as how visitors are going to find the page via a search engine. Some might rely more on advertising than search engines to attract visitors to the site. On the other side of the issue, search engine optimization consultants (SEOs) are concerned with how well a web site works technically and textually: how much traffic it generates via search engines, and how many sales it makes, assuming looks don't contribute to the sales. As a result, the designers and SEOs often end up in disputes where the designer wants more 'pretty' graphics, and the SEO wants lots of 'ugly' keyword-rich text, bullet lists, and text links. One could argue that this is a false dichotomy due to the possibility that a Web Design
may integrate the two disciplines for a collaborative and synergistic solution. Because some graphics serve communication purposes in addition to aesthetics, how well a site works may depend on the graphic designer's visual communication ideas as well as the SEO considerations.
Another problem when using a lot of graphics on a page is that download times can be greatly lengthened, often irritating the user. This has become less of a problem as the internet has evolved with high-speed internet and the use of vector graphics. This is an engineering challenge to increase bandwidth in addition to an artistic challenge to minimize graphics and graphic file sizes. This is an on-going challenge as increased bandwidth invites increased amounts of content.
