Search Engine Optimization (SEO) is the objective of raising the online visibility of site with higher ranking in search engine's list of search results. Sites that are ranked high appear at the top of the list. This encourages visitors searching online to find a relevant site. Good search engine optimization practices help improve a site's ranking, which tends to increase a site's traffic.

In order to list the sites on the Internet, search engines crawl the web by following links that connect web pages and site assets. Search engines evaluate the content of pages and assets in a process called indexing. Indexing is important because it is a constant research that informs search engines of the available content on the web. If a site is no longer available, the search engine removes the website from the search results. Search engines use the results of indexing to determine the content and ranking of sites.

Indexing enables search engines to accurately suggest website links in the search results that match a specific query based on a key word or phrase. For example, if you type "BBC" into a search engine field and click Search, a list of web pages will appear in the search results. The search results display links to websites that the search engine has determined contain content related to BBC as a Corporate entity and all it subsidaries.

There are many parameters that search engines use to decide which websites are listed highest in the list. High ranking is optimal, because that means that people who search on that keyword or phrase are more likely to visit your website. By following the suggestions outlined below, you can help facilitate search engine indexing, so that new visitors searching online will find the sites you create.

Understanding how search engines index sites

Web pages can contain embedded metadata information such as author, keywords, description, and language. The keywords and description are helpful for identifying the site's purpose and describing the content presented. These meta tags are embedded within the HTML source code; they are not displayed visually when the page is displayed in a browser window.

In the past, search engines would evaluate both the metadata keywords and description during the index process. Web designers would sometimes add hundreds of keyword terms, hoping to improve a site's visibility in the search results. Some modern search algorithms, such as Google's search engine, no longer consider keyword values when calculating ranking, but it is worth investing the time to update them. Keywords may improve ranking in other search engines and in Google Search Appliance used by larger websites. Metadata descriptions are often displayed as the description when your page shows up in a search result list, or as the default description in Facebook, Google+, and other social networking sites. An interesting description may help drive traffic to a site.

Search engines often perform full-text indexing, which means that they parse the entire text content on the page. The text that is placed in header tags (h1, h2, h3, etc.) is deemed especially important because headers generally summarize the information being displayed. Using paragraph styles, you can define paragraph tag containers, to create a page that uses an h1 header for the top title in the text content, an h2 header for a subhead title, and an h3 header as a sub subhead title. Text formatting indicates the importance of the header text at each level to search engines. Defining styles to use paragraph tags and applying them to header text enables you to create well-formed HTML code—which search engine crawlers find especially easy to navigate.

As the indexing occurs on a page's content, images and other linked assets are analyzed. If the assets contain titles or alternative text, this text information is parsed. The tooltips added to hyperlinks are also evaluated. The search engine utilizes all of the text content it finds when indexing sites to make informed decisions about each page's content. Additionally, adding titles and alternative text to images and tooltips to hyperlinks ensures that the pages you create are more accessible for everyone, including visitors using assistive devices to navigate the web.

Be sure to check your sites periodically to remove or fix broken links. If search engines detect broken links, they may assume that the site is no longer being updated. Also resolve missing image files or linked assets. Older sites that are not maintained may be assigned lower ranking in search results.

A successful search engine optimisation begins, unsurprisingly, with site design and ultimately on site content. Think about alternative aspects of your site and your business that are more specific to you. Your location may be? Think of other words that describe the type of product or service you are offering, from the specific to the general. The more words you can come up with the better.

Now make sure each page on your site includes the various keywords and phrases you have identified. Use Google to find sites that are related to yours, but not in direct competition with high ranking and add them to your link page. With these simple procedure judiciously implemented, you will be guaranteed a high ranking with Google without paying hundreds of pound to SEO (search engine optimizations) companies.
