Once you’ve identified your priority keywords, the next step is to integrate them into your Web pages. When someone searches on a key phrase, the search engine looks for pages that include prominent mentions of the phrase: ones that contain it a number of times, show it toward the top of the page, and include it in key locations.
Unfortunately, there’s no substitute for the time-consuming task of incorporating your keywords into each content page. For each page, consider how you can incorporate your keywords into:
Headlines and section titles. Text that is formatted prominently (bigger, bolder, higher on the page) is more likely to affect search engine placement than other text, so keywords will hold more weight in headlines.
Link text. The words used as a link to your page are prioritized highly when the search engines consider that page. Optimize the links within your own site and especially any external links you have control over, for example in your blog, email signatures, social network profiles, and so on. Encourage others to link to you using your keywords — for instance, by providing keyword-heavy titles and descriptions for resources on your site.
Page title metadata. Each page has what’s called a “title metadata field,” which controls the text that shows up in header bar at the top of the browser window — and which is also frequently shown as the page title in search engine results. This is one of the most important places to include your keywords. This title field can be edited through the HTML code of the page, or through most methods you might use to update your site — for instance, through Dreamweaver, Contribute, and most content-management systems.
Page description metadata. Each page has a “description” field, a longer description of page content that can be accessed in a similar way to the “title” metadata. The description is another important place to include your keywords, and is also sometimes shown by search engines as the description of your page in search results.
Page text. Repeating your keywords a number of times (but not so many times to annoy your readers, of course) throughout the page text is likely to boost your placement.
