Today’s web, mobile, and IoT applications need to operate at increasingly demanding scale and performance levels to handle thousands to millions of users. Terabytes or petabytes of data. Submillisecond response times. Multiple device types. Global reach. Caching frequently used data in memory can dramatically improve application response times, typically by orders of … Continue Reading...
Exhaustive – Your keyword research should include not only the most popular and frequently searched terms in your niche, but also extend to the long tail of search. Long-tail keywords are more specific and less common, but they add up to account for the majority of search-driven traffic. In addition, they are less competitive, and therefore less expensive.
At the moment, none of the pages link to any other pages and none link to them. If you make the calculation once for each page, you’ll find that each of them ends up with a PageRank of 0.15. No matter how many iterations you run, each page’s PageRank remains at 0.15. The total PageRank in the site = 0.45, whereas it could be 3. The site is seriously wasting most of its potential PageRank.

A Web crawler may use PageRank as one of a number of importance metrics it uses to determine which URL to visit during a crawl of the web. One of the early working papers [54] that were used in the creation of Google is Efficient crawling through URL ordering,[55] which discusses the use of a number of different importance metrics to determine how deeply, and how much of a site Google will crawl. PageRank is presented as one of a number of these importance metrics, though there are others listed such as the number of inbound and outbound links for a URL, and the distance from the root directory on a site to the URL.
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.

On-page SEO refers to best practices that web content creators and site owners can follow to ensure their content is as easily discoverable as possible. This includes the creation of detailed page metadata (data about data) for each page and elements such as images, the use of unique, static URLs, the inclusion of keywords in relevant headings and subheadings, and the use of clean HTML code, to name a few.
Informational searches are those in which the user hopes to find information on a given topic, such as Abraham Lincoln. It wouldn’t make much sense to place ads or other types of paid results on a SERP like this, as the search query “Abraham Lincoln” has very low commercial intent; the vast majority of searchers using this search query are not looking to buy something, and as such only informational results are displayed on the SERP.

The world is mobile today. Most people are searching on Google using a mobile device. The desktop version of a site might be difficult to view and use on a mobile device. As a result, having a mobile ready site is critical to your online presence. In fact, starting in late 2016, Google has begun experiments to primarily use the mobile version of a site's content41 for ranking, parsing structured data, and generating snippets.


Ian Rogers first used the Internet in 1986 sending email on a University VAX machine! He first installed a webserver in 1990, taught himself HTML and perl CGI scripting. Since then he has been a Senior Research Fellow in User Interface Design and a consultant in Network Security and Database Backed Websites. He has had an informal interest in topology and the mathematics and behaviour of networks for years and has also been known to do a little Jive dancing.

A generalization of PageRank for the case of ranking two interacting groups of objects was described in [30] In applications it may be necessary to model systems having objects of two kinds where a weighted relation is defined on object pairs. This leads to considering bipartite graphs. For such graphs two related positive or nonnegative irreducible matrices corresponding to vertex partition sets can be defined. One can compute rankings of objects in both groups as eigenvectors corresponding to the maximal positive eigenvalues of these matrices. Normed eigenvectors exist and are unique by the Perron or Perron-Frobenius theorem. Example: consumers and products. the relation weight is the product consumption rate.
Search intent, accuracy, consumer confidence — if only search engines could read a person's mind when completing a search. Google can’t read your mind, but search engines can collectively measure and determine customer happiness with a local business by looking at that business’ reviews. If customers like a business’ products and services, then they regularly receive 4- and 5-star review, and the opposite is true for negative reviews. If your business has a poor overall rating, you need to work on fixing those issues because not only are those negative reviews harmful for bringing in new customers, they also signal to search engines your business isn’t a good choice for searchers.

It’s good for searchers – Research indicates that searchers click on paid search ads more often than any other form of digital advertising. This means that people really don’t mind being advertised to, provided that the products and services advertised actually fit the searcher’s needs. And because we use search engines when we’re looking for products and services, the results, including the ads, are generally highly relevant to what we’re looking for. Plus, Google has developed an excellent formula for ensuring that PPC ads meet the user’s needs.


Just like the world’s markets, information is affected by supply and demand. The best content is that which does the best job of supplying the largest demand. It might take the form of an XKCD comic that is supplying nerd jokes to a large group of technologists or it might be a Wikipedia article that explains to the world the definition of Web 2.0. It can be a video, an image, a sound, or text, but it must supply a demand in order to be considered good content.
3. Have a discerning eye: learn from every landing page you visit. This applies to your casual surfing, online shopping, research and competitive analysis. After you’ve clicked on a paid ad, take a few extra seconds to observe the landing page and try to pick it apart. What works well on the landing page? What doesn’t? Take these observations and try to apply it to your site. It just might give you an edge over your competitors!
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.

It helps to improve your ranking for certain keywords. If we want this article to rank for the term ’SEO basics’ then we can begin linking to it from other posts using variations of similar anchor text. This tells Google that this post is relevant to people searching for ‘SEO basics’. Some experts recommend varying your anchor text pointing to the same page as Google may see multiple identical uses as ‘suspicious’.
A key objective is engaging digital marketing customers and allowing them to interact with the brand through servicing and delivery of digital media. Information is easy to access at a fast rate through the use of digital communications. Users with access to the Internet can use many digital mediums, such as Facebook, YouTube, Forums, and Email etc. Through Digital communications it creates a Multi-communication channel where information can be quickly exchanged around the world by anyone without any regard to whom they are.[28] Social segregation plays no part through social mediums due to lack of face to face communication and information being wide spread instead to a selective audience. This interactive nature allows consumers create conversation in which the targeted audience is able to ask questions about the brand and get familiar with it which traditional forms of Marketing may not offer.[29]
SEO techniques can be classified into two broad categories: techniques that search engine companies recommend as part of good design ("white hat"), and those techniques of which search engines do not approve ("black hat"). The search engines attempt to minimize the effect of the latter, among them spamdexing. Industry commentators have classified these methods, and the practitioners who employ them, as either white hat SEO, or black hat SEO.[49] White hats tend to produce results that last a long time, whereas black hats anticipate that their sites may eventually be banned either temporarily or permanently once the search engines discover what they are doing.[50]
