Types of SEO
Search Engine Optimizer
Search Engine Optimizers want their client website to come up on the first search engine results page (SERP) against search terms of their choice. For this, the website has to follow good SEO habits. This means information has to be presented logically. Also, they have to bring each and every page up to the mark on SEO with proper page titles, well structured URLs, and plenty of incoming links. Optimizers are experts in information architecture, copywriting, link building, and keyword research.
Paid Search Marketer
Paid Search Marketers (PSMs) are also called Search Engine Marketers. The advertiser pays per click for those search engine ads which are released against keywords. The focus on keyword research means PSMs often work for big companies, and not SEO agencies. They are experts on AdWords and Bing Ads.
Social Media Marketer
Social media marketers work with social media like Twitter, Facebook, LinkedIn, Reddit, Delicious, and StumbleUpon. They want to make brands shine, increase the number of Likes, and drive visitors to client websites. Larger the social network, better the brand awareness. It's an area which cries out for talent.
Conversion Rate Optimizer
CROs make sure site visitors do specific actions. This is what is known as conversion! It’s great if this action is all about shopping!! Or it can indirectly bring revenues, like signing up for a newsletter. CROs work on conversion funnels and landing pages. They are good at selling, A/B testing, design, and the psychology of buying.
Affiliate marketers sell things online for a commission. Though the role is strictly not about SEO, they help with marketing. Leading affiliate companies include Amazon, CJ Affiliate by Conversant, Rakuten Affiliate Network, Kolimbo, etc. Affiliate marketers are good at sales, web development, design, and CRO.
