A search engine is a web-based tool that enables users to locate information on the World Wide Web. Popular examples of search engines are Google, Yahoo, and MSN Search. The information gathered by the spiders is used to create a searchable index of the Web.
How Search Engines Work Step by Step
A web crawler, or spider, is a type of bot that’s typically operated by search engines like Google and Bing. Their purpose is to index the content of websites all across the Internet so that those websites can appear in search engine results. This is the means by which search engines can find out what is published out on the World Wide Web.
How does Web crawler work –
A web crawler copies webpages so that they can be processed later by the search engine, which indexes the downloaded pages. This allows users of the search engine to find webpages quickly. The web crawler also validates links and HTML code, and sometimes it extracts other information from the website.
Web crawler examples –
Focused crawlers, for example, focus on current, content-relevant websites when indexing. Web analysis tools use crawlers or spiders to collect data for page views, or incoming or outbound links. Crawlers serve to provide information hubs with data, for example, news sites, etc
Once a spider has crawled a web page, the copy that is made is returned to the search engine and stored in a data center.
Types of indexing
Primary Index is an ordered file which is fixed length size with two fields. The primary Indexing is also further divided into two types –
a – Dense Index
In dense index, there is an index record for every search key value in the database. This makes searching faster but requires more space to store index records itself. Index records contain search key value and a pointer to the actual record on the disk.
b – Sparse Index
Sparse indexes only contain entries for documents that have the indexed field, even if the index field contains a null value. The index skips over any document that is missing the indexed field. The index is sparse because it does not include all documents of a collection.
A secondary index, put simply, is a way to efficiently access records in a database by means of some piece of information other than the usual key. Secondary indexes can be created manually by the application; there is no disadvantage, other than complexity, to doing so.
Google’s algorithm does the work for you by searching out Web pages that contain the keywords you used to search, then assigning a rank to each page based several factors, including how many times the keywords appear on the page.
PageRank (PR) is an algorithm used by Google Search to rank web pages in their search engine results. PageRank was named after Larry Page, one of the founders of Google.
The fastest searching algorithm
Binary search is faster than linear search except for small arrays. However, the array must be sorted first to be able to apply binary search. There are specialized data structures designed for fast searching, such as hash tables, that can be searched more efficiently than binary search.
Most common search algorithms
- Linear Search.
- Binary Search.
- Jump Search.
- Interpolation Search.
- Exponential Search.
- Sublist Search.
- Fibonacci Search.

Using Facebook for Social Media Marketing
marketing social media
Facebook’s casual, friendly environment requires an active social media marketing strategy. Start by creating a Facebook Business Fan Page. You will want to pay careful attention to layout, as the visual component is a key aspect of the Facebook experience.
Facebook is a place people go to relax and chat with friends, so keep your tone light and friendly. And remember, organic reach on Facebook can be extremely limited, so consider a cost-effective Facebook ad strategy, which can have a big impact on your organic Facebook presence as well.
Using Google+ for Social Media Marketing
Google+ entered the scene as a Facebook competitor, but it now serves a more niche audience. It won’t work for everybody, but some communities are very active on Google+.
On Google+ you can upload and share photos, videos, links, and view all your +1s. Also take advantage of Google+ circles, which allow you to segment your followers into smaller groups, enabling you to share information with some followers while barring others. For example, you might try creating a “super-fan” circle, and share special discounts and exclusive offers only with that group.
Using Pinterest for Social Media Marketing
Pinterest is one of the fastest growing social media marketing trends. Pinterest’s image-centered platform is ideal for retail, but anyone can benefit from using Pinterest for social media purposes or sales-driving ads.
Pinterest allows businesses to showcase their product offerings while also developing brand personality with eye-catching, unique pinboards. When developing your Pinterest strategy, remember that the social network’s primary audience is female. If that’s your demographic, you need a presence on Pinterest!
Using Twitter for Social Media Marketing
social media marketing for dummies
Twitter is the social media marketing tool that lets you broadcast your updates across the web. Follow tweeters in your industry or related fields, and you should gain a steady stream of followers in return.
Mix up your official tweets about specials, discounts, and news with fun, brand-building tweets . Be sure to retweet when a customer has something nice to say about you, and don’t forget to answer people’s questions when possible. Using Twitter as a social media marketing tool revolves around dialog and communication, so be sure to interact as much as possible to nurture and build your following.
Using LinkedIn for Social Media Marketing
LinkedIn is one of the more professional social media marketing sites. LinkedIn Groups is a great venue for entering into a professional dialog with people in similar industries and provides a place to share content with like-minded individuals. It’s also great for posting jobs and general employee networking.
Using YouTube for Social Media Marketing
YouTube for social media
YouTube is the number one place for creating and sharing video content, and it can also be an incredibly powerful social media marketing tool. Many businesses try to create video content with the aim of having their video “go viral,” but in reality those chances are pretty slim. Instead, focus on creating useful, instructive “how-to” videos. These how-to videos also have the added benefit of ranking on the video search results of Google, so don’t under-estimate the power of video content.
Location-Based Social Media Tools
social media marketing for business
Social media platforms like Yelp and FourSquare are great for brick and mortar businesses looking to implement marketing on social media. Register on these sites to claim your location spot, and then consider extra incentives such as check-in rewards or special discounts. Remember, these visitors will have their phones in hand, so they will be able to write and post reviews. A lot of good reviews can significantly help sway prospective visitors to come in and build your business.
Using Reddit for Social Media Marketing
Reddit, or similar social media platforms such as Stumble Upon or Digg, are ideal for sharing compelling content. With over 2 billion page views a month, Reddit has incredible social media marketing potential, but marketers should be warned that only truly unique, interesting content will be welcomed. Posting on Reddit is playing with fire—submit spammy or overtly sales-focused content and your business could get berated by this extremely tech-savvy community.
If you have content you believe the Reddit community (majority is young, geeky, liberal, and internet-obsessed) would enjoy, you could reap tremendous benefits and earn valuable traffic.
