Created by Tim Soulo and Kathryn Aragon, Ahrefs academy provides a digital marketing course that covers various aspects of marketing like keyword research, link building, competitive research, strategic SEO and link acquisition. Every lesson is backed up by a set of clear examples which help subscribers learn marketing concepts and retain them for a long period of time. 

Indexing: Post-crawling content the Spider stores the indexed page in a giant database from where those can be retrieved upon entering a related search string or keyword. For humans this will not be possible, but for search engine, this is every day’s work. Sometimes, the search engines cannot understand the page content. And for that, you need to correctly optimize the page.
Has Instagram taken the world by storm or what? What was a small niche little app until sometime back has today practically left Snapchat behind and is considered next only to facebook in terms of popularity. These courses are tailor made for social media marketers. While facebook ruled the scene for a long while, Instagram is where the focus is shifting now.
Crawling: Every search engine has software, known as Crawler or Spider (in case of Google it is Googlebot), that crawls the webpage content. It is not possible for a crawler to see daily if any new page appeared or any existing page is updated, some crawlers may not visit a webpage for a month or two. In this connection, it should be important to remember what all a search engine can crawl: it cannot crawl image, Flash Movies, JavaScript, Frames, Password protected page, and directories. Therefore, if you have majority of these in your website, it would be better to run a keyword simulator test to see if these are viewable by the spider. Those that are not viewable are not spidered and not indexed or not processed. On the other hand, they will be missing for search engines.
At HubSpot, we talk a lot about inbound marketing as a really effective way to attract, engage, and delight customers online. But we still get a lot of questions from people all around the world about digital marketing. So, we decided to answer them. Click the links below to jump to each question, or keep reading to see how digital marketing is carries out today.
For example, let’s say you want to use Instagram as an acquisition strategy. You would go research all of the ways you can grow your Instagram and drive traffic from it, put them on a spreadsheet, rank the different ideas, then for the three that seem the best opportunities, design a small inexpensive test with a specific goal that spans over a week or two. At the end, check back and see how you did relative to your goal.
