The Secret Benefit Of Search Engine Optimisation: Increased Usabilitythemselves.
6. Headings and sub-headings used
Search engines assume that the text contained in heading tags is more important than the rest of the document text, as headings (in theory at least) summarise the content immediately below them.
Headings are also incredibly useful for your human site visitors, as they greatly aid scanning. Generally speaking, we don't read on the web, we scan, looking for the information that we're after. By breaking up page sections with sub-headings that effectively describe the content beneath them, scanning becomes significantly easier.
Do be sure not to abuse heading tags though. The more text you have contained in heading tags within the page, the less importance search engines assign to them.
7. Opening paragraph describes page content
We've already established that search engines love content, but they especially love the first 25 words or so on each page. By providing an opening paragraph that adequately describes the content of the rest of the page (or the site if it's the homepage), you should be able to include your important keyword phrases in this crucial area.
As web users, whenever we arrive at a web page the first thing we need to know is whether this page has the information that we're after. A great way to find this out is to scan through the first paragraph, which, if it sufficiently describes the page content, should help us out.
8. Descriptive link text
Search engines place a lot of importance on link text. They assume that link text will be descriptive of its destination and as such examine link text for all links pointing to any page. If all the links pointing to a page about widgets say 'click here', search engines can't gain any information about that page without visiting it. If on the other hand, all the links say, 'widgets' then search engines can easily guess what that page is about.
One of the best examples of this in action is for the search term, 'miserable failure'. So many people have linked to George Bush's bio using this phrase as the link text, that now when miserable failure is searched for in Google, George Bush's bio appears top of the search rankings!
As web users, we don't generally read web pages word-for-word - we scan them looking for the information that we're after. When you scan through text you can't take any meaning from the word 'click here'. Link text that effectively describes its destination is far easier to scan and you can understand the destination of the link without having to read its surrounding words.
9. Frames avoided
Frames are quite an old-school technique, and although aren't as commonplace as they once were, do still rear up their ugly head from time to time. Using frames is one of the worst possible things you could do for your search engine ranking, as most search engines can't follow links between frames.
Even if a search engine does index your pages and web users find you through a search engine, they'll be taken to one of the pages within the frame. This page will probably be a content page with no navigation (navigation is normally contained in a separate frame) and therefore no way to navigate to any other page on the site!
Frames are also disadvantageous for usability as they can cause problems with the back button, printing, history and bookmarking. Put simply, say no to frames!
10. Quality content provided
This may seem like a strange characteristic of a search engine optimised website, but it's actually crucial. Search engines, in addition to looking at page content, look at the number of links pointing in to web pages. The more inbound links a website has, all other things being equal, the higher in the search rankings it will appear.
By providing creative, unique and regularly updated content on your website, webmasters will want to link to you as doing so will add value to their site visitors. You will also be adding value to your site visitors.
Conclusion
Optimising your website for both search engines and people needn't be a trade-off. With this much overlap between the two areas, you should easily be able to have a website that web users can find in the search engines, and when they do find it, they can find what they're looking for quickly and efficiently.
