When a search engine user in the targeted area searches for the keywords or keyphrases that you chose, your ad enters an immediate online auction. Your ad is displayed when it matches bid and relevancy criteria, so you want to make sure that you have an appropriate budget size, and that you are bidding on keyphrases relevant to your products/services (such as those indicated on your website or landing page). You are not charged when your ad is displayed, but rather when someone clicks on your ad to take further action.
Website saturation and popularity, or how much presence a website has on search engines, can be analyzed through the number of pages of the site that are indexed by search engines (saturation) and how many backlinks the site has (popularity). It requires pages to contain keywords people are looking for and ensure that they rank high enough in search engine rankings. Most search engines include some form of link popularity in their ranking algorithms. The following are major tools measuring various aspects of saturation and link popularity: Link Popularity, Top 10 Google Analysis, and Marketleap's Link Popularity and Search Engine Saturation.
The home page of your site is usually a good place to start. It typically holds a wide array of information about your product or service and will lead the website visitor to where they want to go. However, if you have other informative pages on your site that you think would be more helpful, you may want to choose one of those pages in addition to, or instead of, the home page.
Companies with stronger SEO efforts on increasing performance emphasised the development of content and updating content on the website as a relatively easy task to perform. However, they start to get lost when it comes to the management of keywords and the construction of external links as the tactics become more difficult to perform. Blogging and the integration of social media were mentioned as simple enough tasks to perform in-house.
Remember when you used to rely solely on search engines for traffic? Remember when you worked on SEO and lived and died by your placement in Google? Were you #1? Assured success. Well, okay, maybe not assured. Success only came if the keywords were relevant to your site users, but it was the only real roadmap to generating site traffic and revenue.
