It is only natural that creating and enhancing the hotel website should be the top priority. Most of the hoteliers are content with having a web site as the sum- total of their Internet marketing efforts. Whereas the fact is that having a website is just a starting point and not the end. Once you have a well designed website in place, it is crucial that you promote it or market it online.

What's the point in spending all that time and effort to create a website which brings in tiny amount of visitors? If promoted properly, your website can generate substantial amount of leads and reservations for your hotel. You need to keep a close eye on latest trends and usability enhancements and accordingly enhance the website at regular intervals. However, more often than not, it doesn't happen. A fine example could be the screen resolution with which websites are designed.

We noticed that a lot of websites still cater to x pixels screen resolution perhaps, even less whereas the current trend is that more and more computers are using a screen size of x pixels or more. Therefore, a substantial amount of web page real estate is going wasted. Another example could be that of images and graphics used on websites. Still, many websites continue to use small sized, highly optimized graphics, thereby compromising on quality and presentation.

These are just a couple of examples. There are several other factors contributing to websites being archaic — verbose content copy, poorly done virtual tours, confusing navigation, and other redundant elements.

Content Copy - Study Your Competition You need to thoroughly study and understand your competition since having an edge over your competitor's website should be one of the primary objectives for your website. In order to do so, you have to understand exactly what your competitors are doing online — the manner in which they display their services, facilities and amenities, use of graphics, search engine penetration, etc.

Write concise and straight forward content copy for your website with appropriate graphics. Graphics and animation go a long way in sending the right message to your visitors. It is important that your website demonstrates your hotel's facilities and amenities in as attractive a manner as possible.

But at the same time, make sure it is searchable. For that to happen, you need to understand what people search for on the Internet and then accordingly plug in the right kind of content and other sales elements into the web pages.

In the online world, your website is your biggest asset. The content that you write for it can either build brand equity or tarnish the brand image of the hotel. Make sure that the agency or SEO specialists that you hire have enough experience and knowledge of hotel selection and booking process. The number of visitors your SEO efforts generate is important. But even more important is the number of reservations generated from these visitors.

Having a lot of visitors to your website would be of little use if they do not help in generating reservations. Therefore, conversion is the key. Having a good link strategy is a very important part of SEO. When ranking your web site, several search engines consider the number and quality of in-bound links to rank your website. Participating in local search — Google and Yahoo — also helps. It also keeps your hotel near the top of search engine results. It is worth investing in Paid Search Campaigns to start with since it brings immediate results as opposed to Organic Search SEO abovewhich usually has a gestation period of three to six months.

The sad part is that many site promoters use PPC to replace and not supplement efforts to improve a web site's ability to earn good organic search results. Organic search should be your goal. User behavior supports this too. Users are more inclined to click on organic search results than paid search results. Finally, as with SEO, remember that the number of reservations or conversions, not simply the number of site visits, determines a Paid Search Campaign's success.
