Hello BHW, I decided to make this list of abbreviations for one reason only: The first time I got here, I knew nothing about Internet Marketing. I had no Idea what SEO was and I had so many questions, this forum had so many abbreviations that I couldn’t understand. I’m just willing to help new people who is not acquainted with these terms and hopefully do some good. This list is my way to say thanks to this wonderful community. Shall we? (ctrl+f for easy-peasyness) ----- BB’s List of Abbreviations for Newbies (Organized Alphabetically) CF - Citation Flow Majestic’s Citation flow is a number in a 0-100 scale used to predict how influential a URL might be. CF uses as a reference how many sites link to this URL. CPA - Cost per Action Cost per Action, or sometimes referred to as cost per acquisition, is a metric that tells you how much you pay in order to attain each specified acquisition (contact request, registration, sale, etc). CPC - Cost per Click Similar to CPA, Cost per Click measures how much your company pays for each click on your ads or your link or whatever you are promoting. CPI - Cost per Impression Cost per Impression is also a metric used when referring to how much you have to pay for each time your Ad is displayed. In some situations, it may be also referred as CPM (Cost per thousand or cost per thousand impressions, where the letter “M” is the roman numeral for 1000). CTR - Click Through Ratio This is an interesting one, this metric is a ratio which tells you the percentage of impressions that resulted in clicks. But if you like formulas, I can help you: CTR = (clicks/impressions) * 100% DA - Domain Authority Domain Authority is a score developed by Moz. It is a 0-100 scaled value which tells you how well a website or domain will rank on search engines. DNS - Domain Name System I know everyone knows this one, please don’t get mad. But for those who doesn’t know, Domain Name System is a system that translates domain names into IP. By the way IP or IP address means Internet Protocol Address, which is your computer (or router) address when it connects to the internet. I didn’t want to split this info in two sections because I think it works better together. IBL - Inbound Linking Inbound links are links from other websites that points to your website. The famous backlinks! IG - Instagram I needed to include this one because I’ve seen people asking what IG is. So for those who doesn’t know, IG is a social media where chicks post their shit. IM - Internet Marketing Pretty straight-forward right ? Internet marketing is a form of marketing that uses internet (duh!) to sell products or rise your business promotion. OBL - Outbound Linking We already talked about Inbound links right? So outbound link is the contrary, these are links in your website that redirects to other websites. OP - Original Poster Really, I’m not joking! I’ve seen people asking what OP is… In this post, for example, OP is this handsome, fascinating and breathtaking human being who's talking to y’all. Thanks! PA - Page Authority Page Authority is a score developed by Moz. It is a 0-100 scaled value which tells you how well a specific page will rank on search engines. PBN - Private Blog Network Private blog network is a network of blogs that works as a link farm to your main website. You main website can be you money site, your client website, etc. The purpose of a PBN is to grant you backlinks in order to rank you on search engines. PPC - Pay per Click Pay per click is a model of advertisement where advertisers pay a fee every time their ad is clicked. CPC is a good metric to keep track of your PPC campaigns. PPI - Pay per Install This model of advertisement is common for mobile applications. An advertiser pays a publisher a commission for every app install, for example. PPL - Pay per Lead This is a model where advertisers pay a publisher for every lead. Leads can be file/software downloads, completion of a registration, a sign-up for newsletter, trial offers, or any other action desired by the advertiser. PPS - Pay per Sale In this model, advertisers pay the publisher for each time the publisher manages to grant a sell through his lead. PR - Page Rank PageRank is an algorithm created by Google to rank pages. ROI - Return On Investment The amount of profit you get from an investment, given in percentage. I think you guys want to taste some formulas, so here it goes: ROI = (Profit / Investment) X 100% For example, if you invested $1000 and earned $3000: Profit = (Total amount earned - Investment) = ($3000 - $1000) = $2000 ROI = (Profit / Investment) X 100% = ($2000/$1000) X 100% = 200% 200% Return On Investment SEO - Search Engine Optimization SEO is strategies, techniques and tactics of increasing your traffic and high-ranking your websites. Or should I say the ART of doing it? TF - Trust Flow Majestic’s Trust flow is a number in a 0-100 scale used to predict how trustworthy a page is based on how trustworthy sites tend to link to trustworthy neighbors. TLD - Top Level Domain Is the most general part of a domain name in an internet address, like: com, net, io, xyz, etc. URL - Uniform Resource Locator URLs are web addresses… ... please, don’t. ----- That’s it Folks!
