Know your websiteWhether you are the marketing manager or webmaster (or both) of your business, you know the products and services on your website better than anyone else. And that means you are in the best position to evaluate your website and assess how a visitor may interact with and respond to the content on your site. Imagining yourself as your prospective customer and fine-tuning your site as necessary can result in a better experience for that prospective customer, and thus better results for you.Some elements to consider as you evaluate your website are:Site structure or sitemap: Are your products and services organized in a way that makes sense from your visitor's perspective? Specific landing pages can help these prospective customers find exactly what they are looking for. For example, if a prospective customer is searching for 'women's snowboarding pants,' the ideal landing page may feature women's snowboarding pants in all brands and styles. If she is searching for a specific brand of snowboarding pants, the ideal landing page may feature all types of snowboarding pants by that specific manufacturer.Layout and design: Visitors to your site may respond more favorably to a site that is straightforward, clean, and simple to navigate than one that is flashy or slick. Those who do not find what they are looking for tend to leave the site within the first several seconds.Ease of use: When visitors come to your site, they should be able to quickly understand how to navigate your site and find the information they're looking for. Navigation and search bars allow your prospective customers to look for more specific items or different styles. Clearly marked buttons that read 'Sign Up Now!' or 'Add to Cart' encourage further action from these prospective customers. On the other hand, broken links, inaccurate or unfinished landing pages and other obstacles make it more difficult for prospective customers to become actual customers.Know your goals Your goals, or desired results, are perhaps the most important thing to keep in mind when setting up a new account or optimizing an existing account. Are you more interested in branding your business, garnering clicks, or maximizing your return on investment? It is important to clearly identify and prioritize what specific goals you want to achieve and design your campaigns around those goals.Depending on what your primary goal is, you may want to consider the following tips:Maximizing clicks: If your aim is to cast the widest net to draw as much relevant traffic to your site as possible, you may want to consider running on a broader range of keyword variations. Keep in mind, however, that running on very general, irrelevant keywords will negatively affect your clickthrough rate, Quality Score, minimum bids and positioning.Optimizing for Ad Performance: One component of improving ad performance is maximizing your clickthrough rate. If this is your goal, the first step is to filter out irrelevant searches by refining your keyword list and incorporating negative keywords where appropriate. In addition, your ad text should ideally reflect a user's search as closely as possible. If you are running on a keyword such as 'San Francisco travel tours,' your ad text should also highlight travel tours in San Francisco.Promoting brand awareness: If you want to promote your brand, you may decide to run a cost-per-impression campaign in addition to a cost-per-click campaign. You may want to supplement your text ads and incorporate image and video ads in your campaign. You could also employ site-targeting to show your ad to people who aren't actively searching for your business but may still be interested in what you sell. Maximizing ROI: Maximizing your return on investment calls for a little more understanding about the sales cycle unique to your product or service, and how keyword searches can reflect which stage a user might be in that cycle. If you want to separate the serious buyers from the online equivalent of window shoppers, your structure, ad text and keyword lists can be designed to target specific kinds of users. For instance, users searching on variations such as 'reviews' or 'ratings' are probably still researching the product, and you can filter out such searches by including those words as negative keywords.Last but not least, it is important to determine how you will measure the impact of your optimization so you can clearly evaluate your campaign's performance before and after the optimization. If you are feeling extra scientific, you may want to test altered campaigns against a control group to see what works best for you. Google offers some powerful tools that can help you better track campaign performance, including Analytics, conversion tracking, and the Reports Center tab in your account.
