Broad Match – A type of keyword matching that will show your ad for the widest variety of terms deemed relevant by the search engine. In general, broad match keywords give a higher volume with a lower conversion rate.

Broad Match Modifier – A type of keyword matching that will show your ad when missing a derivative while keeping the order of the terms.  This is used by adding +before each term.

Campaign – A set of ad groups. Even though each ad group can contain different keywords and ads, the campaign has a daily budget, geographic targeting, and other settings which will be effective for all the ads in the campaign. Once the campaign’s daily budget is exhausted, all the ads in the campaign stop appearing for their relevant keywords.

Channel – In content match, one of the websites where your ad is showing. You can choose specific channels or sets of channels, so you can choose to be on Facebook, or on certain sections or demographics where your ad is likely to get better results.

Click Fraud – Clicks from fraudulent activity. Some fraud comes from competitors intentionally clicking on your ad. Other fraud involves using automated tools to collect commissions for clicks (via channels like Google Adsense) or to exhaust your daily budget.

Content Bid – The default bid for a set of keywords on the content network. Note that this should be a fraction of your search bid.

Content Matching – The placement of PPC ads on websites. Ideally, these sites should have content that is relevant to the service offering of the company running the ad. Google runs content matching on its “content network.”

Contextual Advertising – Essentially the same thing as Content Matching, given that your ad is triggered by keywords in context on a news, article, blog, or content page.

Conversion – A desired action taken by a website visitor. With PPC, it is relatively easy to measure conversions on form fill-outs and purchases, but it is more difficult to quantify dollars earned from phone calls triggered by online ads. Search engines track visitors for up to 30 days, so your conversion may not happen until a subsequent visit several days later.

Conversion Rate – The percentage of times your ad resulted in a form fill-out, sale, or action. To calculate conversion rate, you take the number of actions divided by the number of clicks. A typical e-commerce conversion rate may be 2.5%, but a form fill-out conversion rate could be 10-20%. A very low conversion rate indicates problems.

Cost Per Conversion – The dollar cost associated with the conversion rate. If you had 100 clicks for one dollar each, and had a 5% conversion rate (5 conversions), your cost per conversion is $20. The formula is essentially the dollar cost divided by the number of conversions.

CPC – Cost Per Click. How much each click cost you. Because bidding is based on many factors, this amount is generally expressed as an average of multiple clicks. When applied to “advertising” it is synonymous with Pay-Per-Click (PPC)

Creative – The text of a PPC Ad. In Google, the first line of your creative is 25 characters, the second and third lines are 35 characters.

CTR – Click Through Rate. The actual number of clicks on your ad divided by the number of impressions.

Dynamic Keyword Insertion – The placement of a variable field in ad text that will show a searcher’s actual search phrase (within limits) in the body of the ad.

Exact Match – A keyword setting that only lets your ad show up when a precise keyword is searched upon. In Google Adwords, brackets are used for an exact match, so a keyword like [vegetable man] would only trigger an ad when that phrase is typed in with no words before, after, or between those two words.

Geotargeting – In a campaign, setting your ads to appear in a certain city, state, or country. Also called Local Matching.

Keyword – A word or phrase that triggers an advertisement. Keyword matches can be based on broad match, phrase match, or exact match. Negative Keywords can be used to keep ads from showing for the wrong searches.

IMI – Internet Marketing, Inc  –  The best internet marketing company in the world.

Impressions – Number of times your ad is served up, either as a search match or through content placement.

Impression Share – The % of impressions a campaign is visible for while the campaign is active.

Landing Page – The web page that the display ad or keyword “lands” on when an ad is clicked. If there is not a specific page assigned to an individual keyword, the landing page is determined by the “default URL” in the ad.

Negative Keyword – A keyword that is used to determine when an ad should not be shown. For example, if you have a campaign about computer keyboards, but don’t sell wireless keyboards, then you would add “-wireless” to your list of keywords. Anyone typing in “wireless keyboards” would not see your ad because the negative keyword excludes it.

Phrase Match – A keyword matching type that only shows your keyword when someone types in the specified phrase in a search query. With phrase match in Google Adwords, quotes are used around the keyword, so a phrase match designation for “dog food” would trigger an ad when someone typed in a search for “best dog food recipe.”

Position Preference – A setting that specifies the desired position of your PPC ads. Note that this can sometimes keep your ad from showing.

PPC – Pay-Per-Click. A model of serving ads where you only pay when someone actually clicks on the ad.

Quality Score – A somewhat complex formula used by search engines to decide whether your keywords are relevant to the landing page, how much trust your campaign has, and the click through rate on your ads. Changing an ad can change its quality score, so it is usually best to copy the ad and edit it, then pause the old one when the new one has gained its own quality level. There are also geographic and bidding factors.

Query String  –  A query string is a variable added to a destination url for 3rd party tracking software’s to track the source and keyword that the visitor came from.

ROI – Return On Investment. There are various ways to calculate the value of a PPC campaign. Normally it takes at least a month to ramp up a campaign and gain a quality score, and more time to determine buying patterns and seasonality. PPC ROI can be tough to track beyond the simple cost/benefit analysis, but if clicks are not resulting in profitable sales, then improvement is called for on the site and in the campaigns.

ROAS – Return On Ad Spend. There are a variety of formulas for Return On Ad Spend.  Removing your margins and calculating Cost / Revenue is the simplest calculation.

UTM Code – This is Google method or Query String used to tag a destination url.  Example UTM_Source=Google&UTM_Medium=PPC
