SEO (Search Engine Optimization) is to improve the ranking of website on search engines’ result pages by optimizing the website and adding quality backlinks
"SEO" or "Search Engine Optimization" is a method of adjusting a website, which includes improving content and adding backlinks, which are quality links to the website, in order to promote the website to be ranked high on the Search Result Page when a keyword is searched through a Search Engine such as Google, Yahoo!, Bing, etc. This is an effective method for increasing website traffic in the long run.
Currently, many people search for information through Google, which is one of the main Search Engines in many countries including Thailand, the United States, England, India, Japan, etc. Therefore, SEO on Google is primarily focused on. However, each Search Engine has similar principles, which is "User Experience (UX)". Therefore, SEO according to Google's principles will emphasize making a quality website that provides information that matches the searched keyword, and this can also affect SEO in other Search Engines.
Example of search result from Google.co.th with the keyword "รับทำ seo"
In the red frame, it represents the "Organic Search" or also known as "Natural Search". In this section, it shows all the website data that is collected by the search engine system such as Google, using an algorithm to rank the websites. The score is based on the criteria set by each search engine, and the website owner cannot select their position on the search result. Therefore, the method to improve the website ranking in the top positions on the search result is called "SEO" or "Search Engine Optimization", which is a part of "SEM" or "Search Engine Marketing".
As for the text above the red frame with the word "Ad", it represents the section for advertising on the search engine, which is called "PPC" or "Pay Per Click". It involves keyword bidding for displaying ads, and there will be a cost per click. It can achieve a fast ranking without website improvement, while SEO does not require cost per click but takes time to develop a website and create quality content to rank the website in the best position on the search result.
The ranking system of displaying search results on the Search Result Page is called "Algorithm". Each search engine has its own algorithm system for scoring websites differently, and the system is constantly updated to filter out low-quality websites and provide the search results that users want the most. Therefore, it is necessary to create high-quality websites and content that meet the algorithm's standards in order to achieve the best rankings.
The algorithm used to rank websites in Google, which is the main search engine used in Thailand and many countries around the world, consists of more than 100 factors. However, we can summarize the algorithm into 2 main factors, which are:
Internal factors come from the optimization of website structure and content. This is the most important part of SEO for ranking. They include:
Off-page factors that contribute to SEO include backlinks or links from other websites. These can be links that others create for our website, such as references to our information or links that we create ourselves, such as posting articles on other websites or registering our website in web directories. These off-page factors can be divided into:
SEO Marketing, or marketing through SEO, can be considered an important process for online businesses that have their own website. In addition to improving the website's ranking on search engine result pages, SEO also offers many other benefits, such as:
Currently, there is an increasing number of people searching for information through search engines. If a website ranks high for keywords that users frequently search for, there is a higher chance of having a high website traffic. Additionally, when a keyword is ranked high, keywords that are similar to it will also rank high. Thus, more visitors will come from other keywords that were not optimized through SEO. Furthermore, if SEO is consistently updated with new information, website traffic has a higher chance of continuously increasing. This can create a loyal customer base and help the business grow sustainably.
SEO is a way to make the website searchable with specific and targeted keywords. It is a targeted online marketing approach. Visitors who come to the website through a search engine are already interested in those keywords, making them more likely to buy the products or use the services offered on the website. In addition, having more website visitors increases the chances of selling products or services even further. This is a marketing approach that can effectively increase the conversion rate, the proportion of visitors who take additional actions on the website.
Typically, when people search for information through a search engine, they will only open websites that are on the first or second page of search results. Having our website appear on the first page, especially in the top ranks, will make the website's name visible and well-known, even if people haven't clicked to see the content on the website. This creates good brand awareness, and importantly, people tend to trust websites that are at the top of the search results, giving confidence and trust to businesses that can rank high in search results. This makes it easier for people to make decisions to buy products or use services on those websites.
Since SEO takes some time for the website to rank on the first page, it is suitable for long-term marketing. Additionally, clicking on a website through SEO does not incur costs like PPC advertising directly with search engines. This can help reduce advertising costs, and SEO is relatively cheaper than advertising with other media. However, if you choose to do SEO with popular keywords that many people use, the cost may be high due to high competition. Therefore, when selecting keywords, it should be appropriate for marketing purposes and the value of the investment.
The strategy for achieving the greatest success in SEO is "to make SEO as natural as possible, with a focus on the user." This will result in a website that is truly of high quality and ranks sustainably, without having to worry too much about updating algorithms. The main methods for achieving this are as follows:
On-page SEO is a method of improving the content and structure of a website, both in terms of coding and design, within the website's pages.
Off-page SEO refers to using external factors outside of the website to help improve its ranking, which includes links or backlinks from other websites to our website.
After doing SEO for some time, you will start to see improvements in your ranking, which depends on the quality of the content on your website, competition in the relevant keywords, and the quality of your competitor's website. Generally, the ranking will gradually improve over time. If your website's ranking is not satisfactory, it is necessary to add more content to the website and increase the number of quality backlinks.
These factors are not confirmed by Google to affect rankings, but they are signals that indicate whether a website is high quality or not. This can serve as a guide for developers or website administrators to make improvements.
Copying content from other websites without reorganizing or without permission or without citing the source is prohibited, including using copyrighted images because the content or image owners can submit a report to Google (Copyright Removal) to remove our website page from the search results due to copyright infringement. This can cause our website page ranking to disappear immediately.
Avoid using pop-up ads that cover the entire screen and obstruct the content on the web page, as Google considers them to be intrusive to the user's browsing experience (Intrusive Interstitials), which may result in a penalty and negative impact on website ranking. If it is necessary to use pop-up ads, it is recommended to display them after the user has scrolled and read the page for a certain amount of time, and to limit their size to about 20-30% of the screen with a simple-to-close X button. Pop-ups should not appear every time a new page is opened.
Websites that are hacked often involve changing the website's page and locking the website to prevent it from being used. It definitely affects the rankings in search results because the content on the website has disappeared. In addition, there are also hacks where data is secretly edited, such as inserting other content, or embedding Malware and viruses on the website. When Google detects this problem, it will display the message "This site may have been hacked" under that website on the search results page to alert people who click to enter. This can have a negative impact on SEO efforts.
