I. Introduction:

Search Engine Optimization typically referred to as SEO is a strategy that enables businesses to improve the ranking of their websites on these or other search engines. The objective is to enhance the website traffic only through organic search by improving website rankings on Search Engine Results Pages (SERPS). Out of all the digital marketing instruments, SEO deserves special mention, as this instrument permits to reach the targeted audience directly. Even though, unlike paid promotion (PPC), it is clearly much difficult to rank a site because it is a much longer process and gives return over a period, SEO remains as one of the most important tools.

II. General Overview of Search Engines

Once you know the basics of SEO, you may want to delve deeper into the operations of search engines. Search engines have specific algorithms for how to rank the sites with criteria like relevance, quality and user experience.

1: Search Engine Algorithms

A ranking algorithm like PageRank from Google considers up to hundreds of criteria in ranking a page. These factors consist of keyword, usage, whether the site is mobile responsive among others. The primary consideration when applying these ranking features is how to rank the website better.

2: Crawling, Indexing and Ranking

• Crawling: Crawlers are computer programs that search for new or updated content across the web.

• Indexing: The existence of a large catalogue of webpages is referred to as an index.

• Ranking: When a word or words are searched in an engine, relevant pages from that engine index are retrieved and arranged in a ranked order ready for the target user.

3: User Intent

Search engines always attempt to fulfill the purpose of the search which is the one in existence and indeed most relevant to the searcher. Creating content that addresses different user intents, be it navigation, seeking information, or making a purchase can improve SEO remarkably.

III. SEO’s Major Structural Elements.

The activity of Search Engine Optimization comprises three main types: optimization within the page or on-page; optimization outside the page or off-page; and technical optimization.

1: On Page Optimization:

This is the arba of SEO that deals with making improvement on the specific web pages targeting better ranks in the search engines. Major activities include:

• Word Research and Placement:
  This is the preliminary phase carried out to any page that is targeted for optimization. It tends to help in determining the relevancy of a particular piece of work through locating some of these words in your content and other stable pages.

• Descriptions And Keywords Meta Tags:
  These are short snippets of HTML that contextually elaborate on the main body of a particular webpage. An interesting and keyword optimized meta title and description usually increases the CTR from searches.

• SEO Content:
  SEO is emerging around content. Therefore, quality of the information and its presentation is pretty much important and will always be. The content will give answers to the user’s questions, but it will have to deliver some more. It is indeed indispensable to hear these words from an SEO.

• Links within the Site:
  Internal links are all those hyperlinks which point to any page on your site. These types of links are useful to both site visitors and search engines. Proper use of internal links ects link juice and enhances search engine optimization.

2: Off-Page SEO:

The Off-page SEO is concerned with actions done outside the website in question in order to improve the authority of the website.

• Backlink building:
  Backlinks are links from other websites back to the present site. A good quality backlink profile is an important thing for search engines as they use it to determine the credibility level of a website hence assisting in ranking it higher.

• Guest Posting and Outreach:
  It is through collaboration with influencers or partners, and writing guest posts for credible sites regarding your niche that enhances high-quality backlinks to your site.

• Social Signals:
  Social shares in social networking sites have no immediate effect on the on-page SEO, although proper use of social networks may help to indirectly promote rankings since traffic and brand awareness is increased.

3: Technical SEO:

Technical SEO is ensuring that the structure of the site will make easier for search engine robots to reach your content and index it.

• Site Speed and Performance:
  This obvious trend is dictated by normal human behavior: if it takes too much time to load a page, a user simply closes it and does not come back. Google has put it bluntly, site speed is definitely a ranking factor.

• Mobile Optimization:
  Due to growing mobility, a responsive and mobile friendly website is very much important. Today, Google has adopted a mobile first indexing approach, which means it prefers using the mobile version of a site to rank its pages.

• Structured Data and Schema Markup:
  This is important since rich snippets such as review stars or event dates can contribute to drawing visitors to the SERP by improving their CTR.

• SSL and Security:
  Placement of a HTTPS version of a website helps to improve search engine rankings. Google marks websites lacking an SSL certificate as “not secure”, thereby causing a dip both in ranking and trust of the website.

IV. Significance of SEO in the Digital Marketing Strategy

SEO is a step or tool and not something that should be viewed in isolation from the overall digital marketing framework.

1:Organic Search vs. Paid Search

SEO and paid advertising such as Google Ads are processes that work simultaneously. While SEO helps to provide an influx of website traffic in the long term, paid targeted search provides almost instant traffic. Maximizing both approaches is optimal for businesses.

2:SEO as a Long-Term Strategy

Specifically, it is accepted that the result of implementing the SEO approach takes time. At the same time, the effect of such action lasts longer, rather than immediately as with paid search. It requires investment to get traffic; as soon as you stop paying for ads on search engines, traffic ceases, on the other, traffic through SEO keeps coming with no ad spend.

3:Local SEO for Businesses

As a business strategy, local SEO aids people searching for queries which are not that far from their locations. Attempting to use local keywords, Google my business and broad reviews as part of local SEO benefits is critical to businesses that have a building based imagery.

4:Integrating SEO with Content Marketing

Content marketing and SEO go together as a strong combination in the right hands. Good content leads to links, social sharing and online presence which aids in enhancing SEO. Producing information that is correct to the readers’ questions and suitable for search engines provides prospective enhancement of SEO and digital marketing of the audience.
