What is technical SEO strategy?

SEO (Search Engine Optimization) is to set up the website so that Google Bot (Crawler for collecting data of Google Search Engine) can smoothly collect information on the page, Depending on the business, it is the task of creating contents based on the keywords customers want, arranging the generated central elements well throughout the page elements, and displaying them as more important. Through such operation, the crawler downloads the content of the page, and our content is analyzed by Google's page content analysis algorithm and waits for the page content to be retrieved by the user. Among these series of works, we will look at five strategies that must be considered technically.

1. Title&Description Tag

Title Tag should not be overlooked because it appears in the largest size at the top of the search results. It should be filled with the words the customer wants, and it should accurately represent the point of the page. Of course, listing only a few words and writing in meaningful sentences does not show a big difference when collecting information from Google search engine (as of now), but as time goes on, Google scores on titles that consist of complete sentences. seems to give more Google's sentence understanding algorithm is developing at a much faster rate than we can imagine, and the meaning of the development is to understand the intent of the sentence written in the title, and also to identify the intent of the sentence used when the searcher searches and match it. It means you are continuing to do what you are doing. Then, in the end, the Page Ranking that clearly indicates the intention of the page is inevitably higher.

Apart from the mechanism of Google bot, searchers who want search results are more attracted to titles that seem to resolve their doubts. Listing only words is not an answer for searchers, it is just a series of meaningless letters.

Therefore, for the mechanism of the Google Search Bot, or to show that the page is meaningful to searchers, it is better to express it accurately in full sentences.

Description Tag, on average, is about 20 to 25 words to appear in the search results. Of course, it doesn't matter at least that there are more words in the Description Tag, but it should be taken into account that words with more than 25 words will not appear in the search results. So, the best description is a sentence that can persuade searchers within 25 words. I think the best way is to present the answers to the questions that searchers are curious about in sentences.

2. H1-H5

The pages of almost all websites consist of up to 1000 words or more. If you look at Google's crawling mechanism (, Google will parse the text, images, and videos of the page once. It downloads and uses Google's analytics system to analyze and categorize various elements of the page.

From the standpoint of analysis and classification, it is impossible to give the same weight to all texts on the page. Because, from Google's point of view, the main goal is to understand the "intent" of the page (as explained in the title, it is the search engine's existence to understand the page's intent and deliver the page to the searcher with the desired intent. reason), and which keywords to focus on. In that sense, H1~H5 tags can be the main headings of any paragraph in the page, and also when using such tags, the intention of the paragraph should be well expressed.

3. Canonical Tag

Canonical Tag is a tag that should be used when multiple URLs pointing to the same page exist. For example, suppose that exists, and if a page with the same content is linked by another bulletin board, the bulletin board contains This could be /example1.html?id=777. Then these two URLs are linked to the same page, but they can be recognized as different URLs. In this case, the Search Engine ( can recognize the contents of the same page as different URLs, and then Page Ranking is will be divided If you add up the two urls, you will get a much larger number of ranking points, but since they are divided, the website owner is unfairly losing the ranking of the page.

So, in this case, use <link rel="canonical" href="" />

4. front advertisement Popup

In some cases, the text content of the page that should be displayed is not visible by making an interstitial advertisement popup on the page for a specific event. In this case, Google Bot cannot collect the contents. Therefore, when it is necessary to show event advertisements, it is recommended from the SEO point of view to allocate a certain part of the page, whether at the top, left or right, and show it in a banner format.

5. image

In building a website, images are an essential element in creating content. Images often determine the quality of a page. So we have to consider the following factors when we want to use images.

  • Are there any meaningless pictures? It looks good, but sometimes contains photos that are not related to Contents. When the search engine collects and analyzes the page of the website, it does not analyze only the text. Images on the page are also classified separately, and if the images are meaningful, the website can be notified to the searcher through Google's image search.
  • Therefore, you should use an image that can explain the contents well, and use the alt tag of the image to explain the image well.
  • If you search for an image with the keyword "alt tag image", you will get the following result. The image can be found on the ( site, and the alt tag work on the site is as follows. "What is an alt tag?".
  • What the image is trying to say, we can see that it is an image designed to arouse the searcher's curiosity and is an "alt tag".
  • Images also greatly affect the speed of page loading. It takes a lot of time for the web browser to download the image because the size of the image has to be increased in order to post high-quality photos on a website. So, we guarantee full page loading speed only if we use images with high quality but small size. What we need to know in this section is image compression technology, and we are grateful that this technology continues to evolve along with the development of the Internet. The webp type image is one of the advanced technologies, and in my experience, it reduces the size of jpg, which is often used, by more than 50%. What this means is that you can post twice the quality of photos on your website, even with the same image size as before. In other words, a web browser can download a picture of the same quality twice as fast.
