Lost IS (rank), aka “Quality Score too low” – Are your Keyword Quality Scores (QS) below 5/10? Per Google, since “Ad Rank” is a calculation of your Bid and QS, it would behoove you to improve Quality Scores by focusing on increasing CTRs in your Ads and Keywords. Improve CTRs by tightening up Ad Groups that only consist of closely related keywords and Ads that are the most relevant to these keywords.
You can focus on your targets so you can write targeted ad copy and bid/budget appropriately. You can do this based on categories, URLs, page titles, or page content. For example, you could set a target for all URLs with “purple-shoes” in the string. That would allow you to know all searches and ads will be about purple shoes, so you could write ad copy and bid accordingly.
PageRank is one of many, many factors used to produce search rankings. Highlighting PageRank in search results doesn’t help the searcher. That’s because Google uses another system to show the most important pages for a particular search you do. It lists them in order of importance for what you searched on. Adding PageRank scores to search results would just confuse people. They’d wonder why pages with lower scores were outranking higher scored pages.
Search engine advertising is one of the most popular forms of PPC. It allows advertisers to bid for ad placement in a search engine's sponsored links when someone searches on a keyword that is related to their business offering. For example, if we bid on the keyword “PPC software,” our ad might show up in the very top spot on the Google results page.
Remember, depending on your targeting methods, the placement might not be that important. If you’re targeting the user through interests or remarketing, the placement is just where that user visits. Of course, some sites will still perform better than others, but keep in mind which targeting method you’re using when evaluating placement performances.
Ad extensions are additional links and details that show supplementary information about your business to enhance the basic PPC ads. Certain ad extensions are manual choices, which you can control. Search engines may also automatically generate some ad extensions. The main advantage of ad extensions is that they help improve the click-thru-rate (CTR) of the ad headline because the ads are larger in size and therefore more prominent on the search engine results pages (SERPs). There are many ad extensions.
Search engine optimization (SEO) is the process of affecting the online visibility of a website or a web page in a web search engine's unpaid results—often referred to as "natural", "organic", or "earned" results. In general, the earlier (or higher ranked on the search results page), and more frequently a website appears in the search results list, the more visitors it will receive from the search engine's users; these visitors can then be converted into customers. SEO may target different kinds of search, including image search, video search, academic search, news search, and industry-specific vertical search engines. SEO differs from local search engine optimization in that the latter is focused on optimizing a business' online presence so that its web pages will be displayed by search engines when a user enters a local search for its products or services. The former instead is more focused on national or international searches.
