Web positioning techniques aim to optimize a website's content and links to appear at the top of search engine results. There are two types of search results - paid advertising results and organic or natural results obtained through search engine optimization (SEO). SEO focuses on unique, relevant content and link building to improve organic rankings. Search engine marketing (SEM) involves paying for advertising placements on search engines through pay-per-click bids on relevant keywords. SEM tools help automate bidding and campaign management to drive targeted traffic.
