Interests are very similar to Topics. In fact, they are the same themes. However, the key difference is that Topics target websites and Interests target users. Google gleans user interest based on browsing history or self-selected interests if they’re logged in to their Google account. This allows your ads to appear on whatever site someone with your targeted interests is on, even if that site isn’t related.
For example, to implement PPC using Google AdWords, you'll bid against other companies in your industry to appear at the top of Google's search results for keywords associated with your business. Depending on the competitiveness of the keyword, this can be reasonably affordable, or extremely expensive, which is why it's a good idea to focus building your organic reach, too.
The PageRank concept is that a page casts votes for one or more other pages. Nothing is said in the original PageRank document about a page casting more than one vote for a single page. The idea seems to be against the PageRank concept and would certainly be open to manipulation by unrealistically proportioning votes for target pages. E.g. if an outbound link, or a link to an unimportant page, is necessary, add a bunch of links to an important page to minimize the effect.
A rich snippet contains more information than a normal snippet does, including pictures, reviews, or customer ratings. You can recognize a rich snippet as any organic search result that provides more information than the title of the page, the URL, and the metadescription. Site operators can add structured data markup to their HTML to help search engines understand their website and optimize for a rich snippet. The Starbucks app, for example, includes customer ratings and pricing within the search description.
Facebook Ads, which has an unparalleled targeting system (and also allows you to advertise on Instagram). Facebook Ads has two main strengths: retargeting based on segmented marketing and custom audiences and the ability to introduce your brand to customers who didn’t know they wanted it. Google AdWords is all about demand harvesting, while Facebook Ads is all about demand generation.
Your entire PPC campaign is built around keywords, and the most successful AdWords advertisers continuously grow and refine their PPC keyword list (ideally, using a variety of tools, not just Keyword Planner). If you only do keyword research once, when you create your first campaign, you are probably missing out on hundreds of thousands of valuable, long-tail, low-cost and highly relevant keywords that could be driving traffic to your site.
If Google finds two identical pieces of content, whether on your own site, or on another you’re not even aware of, it will only index one of those pages. You should be aware of scraper sites, stealing your content automatically and republishing as your own. Here’s Graham Charlton’s thorough investigation on what to if your content ends up working better for somebody else.
In February 1998 Jeffrey Brewer of Goto.com, a 25-employee startup company (later Overture, now part of Yahoo!), presented a pay per click search engine proof-of-concept to the TED conference in California. This presentation and the events that followed created the PPC advertising system. Credit for the concept of the PPC model is generally given to Idealab and Goto.com founder Bill Gross.
While most of the links to your site will be added gradually, as people discover your content through search or other ways and link to it, Google understands that you'd like to let others know about the hard work you've put into your content. Effectively promoting your new content will lead to faster discovery by those who are interested in the same subject. As with most points covered in this document, taking these recommendations to an extreme could actually harm the reputation of your site.
However, the SERP of major search engines, like Google, Yahoo!, and Bing, may include many different types of enhanced results (organic search and sponsored) such as rich snippets, images, maps, definitions, answer boxes, videos or suggested search refinements. A recent study revealed that 97% of queries in Google returned at least one rich feature.
Now, how much weight does PageRank carry? Like most every other part of the algorithm, it’s questionable. If we listed all the ranking factors, I don’t suspect it would be in the top 5, but it’s important to remember that the key to ranking well is to be the LESS IMPERFECT than your competition. IE: To have more of the right things that send the right signals in the right places so that Google sees you as a better, more relevant, candidate for the top three on page one. If you and your competitor both have optimized (on-page and technically) for the same keyword phrase perfectly, PR could be the deal breaker that pushes your blue link an inch up.
Using digital marketing without a strategic approach is still commonplace. I'm sure many of the companies in this category are using digital media effectively and they could certainly be getting great results from their search, email or social media marketing. But I'm equally sure that many are missing opportunities for better targeting or optimization, or are suffering from the other challenges I've listed below. Perhaps the problems below are greatest for larger organizations who most urgently need governance.
Webmasters and content providers began optimizing websites for search engines in the mid-1990s, as the first search engines were cataloging the early Web. Initially, all webmasters needed only to submit the address of a page, or URL, to the various engines which would send a "spider" to "crawl" that page, extract links to other pages from it, and return information found on the page to be indexed. The process involves a search engine spider downloading a page and storing it on the search engine's own server. A second program, known as an indexer, extracts information about the page, such as the words it contains, where they are located, and any weight for specific words, as well as all links the page contains. All of this information is then placed into a scheduler for crawling at a later date.
