An underused sitemap is a real missed opportunity, both site-side and in XML form. In XML format, a sitemap is the search engine’s blue print for your site. It tells the search crawlers which pages exist and where they can be found. The sitemap protocol is both scalable and open to personalization, meaning it can be applied to the smallest and largest of sites and developed by more advanced users.
In its most basic guise, an XML sitemap is simply a list of all of the pages on your site along with their links. If you’ve already submitted this information to the search engines, step it up by adding additional data. Google accepts a raft of extra info to enable its crawlers to work more intuitively through your site. Try the following:
date last modified
frequency of modification ie hourly, daily, monthly
While these changes won’t have a direct impact on your search ranking, they will contribute to better search visibility by telling the search engines exactly how your site is organized and updated. This allows the web bots to build a more complete picture and guides them through all pages of the site, not just pages found via internal or external links.
It’s important that the XML sitemap is updated to reflect new additions to the site. After all, there’s no point in creating a new page of optimized content if the search engines can’t find it.
Within the site itself, there is more scope to be creative with your sitemap. Often, web designers will leave a sitemap in its most basic form – as a list of links to pages within the site. Making your sitemap more visitor friendly by dressing it up with text, organizing according to theme or adding short descriptions will turn a run of the mill page into a useful SEO tool.
Rather than a standard link to your sitemap from every page of the site, use a followed link from the homepage and then add a ‘nofollow’ tag from every other page on the site. This will deliver PageRank to the site map from the homepage. For links from the site map to other areas of the site, use a standard followed link coupled with optimized anchor text. Optimized text links must feature a primary keyword from the destination page. You can top this up with a small description, allowing the reader to asses whether or not that is the page they are looking for.
An additional one or two lines of information per link can change a run of the mill sitemap into a useful index or content page. Some pages will need no running commentary – think of a magazine index, where the most important features are accompanied by a blurb and self explanatory pages are left to stand alone. This same approach can be adopted when designing your on page sitemap.
Google does not like to see pages with more than 100 or so links. If you’re creating a sitemap for a big site, this could become an issue. Fortunately, there are no rules about the number of sitemaps per website so take Google at their word and break the sitemap into separate pages. To make sure your end user isn’t left confused or frustrated, organize your sitemap according to product or topic so it remains easy to navigate to the desired site area.
