A sitemap is definitely an often overlooked file which enables modern engines like google index and understand websites better. Google was the first to introduce sitemaps while using Google XML sitemap format in 2005. A little more than a year later, Google abandoned his proprietary sitemap format and joined other search companies to make an XML sitemap standard. This new standard has replaced the last Google XML standard which is used now by Google, Bing, Yahoo, as well as other search companies. Because the web evolves, the standard evolves by it and the search engines like yahoo look toward the conventional for guidance on how best to complete their website indexing and website crawling.
Essentially an XML sitemap is merely an XML file used in a directory of an online site that contains URLs plus some information about those URLs. An online site can have multiple sitemaps put in multiple directories. To help search engines get the various sitemaps an organization might have, the locations with the XML file are listed towards the bottom of a website’s robots.txt file.
An XML sitemap will last websites where some pages are updated more often or where some pages tend to be more important than these. For example, a local business might update its hours frequently while rarely updating the page describing the history of its business. If that’s the case, the webmaster may want to inform engines like google to place a higher priority around the hours page if this does its normal website crawling. Likewise, the webmaster can put a higher concentrate on the hours pages or possibly on other pages with special content, so the search engine’s website indexing ranks those pages higher.
Sitemaps should contain the date a webpage was last modified, how often that page changes and that page’s priority. The past modified date is simply the calendar date the page last changed. The frequency that a page can change can be hourly, daily, monthly or a number of other values. The priority is often a value from zero to 1 with a default of 0.5.
Writing out these records for each page is not difficult, however it can be tedious. Utilizing an XML sitemap generator will help reduce the work a webmaster has to do when writing the sitemap. Several websites produce an online sitemap generator while other websites provide offline generators.
Most XML sitemap generators have the freedom to use tools, even though they use to limit the volume of pages they’re able to crawl. If the website contains many thousands of website pages, you should use a specialist sitemap creator instead.
Although a sitemap is frequently overlooked, it’s an important resource that can help search engines understand websites. Sitemaps might be basic or complex, based on the website’s size and requires. Both basic and complex sitemaps are useful to search engines, so webmasters without a sitemap should create no less than a basic XML sitemap immediately.
