As vibe coding becomes part of everyday life, there is a growing number of cases where non-developers without coding knowledge are creating websites using AI, even without using web builders. Individuals are building personal websites, such as portfolio sites, while companies are using AI tools to create corporate websites to reduce costs. A variety of related tools are available. Lovable, Claude Code, Cursor, Google AI Studio are currently gaining popularity as vibe coding tools.
However, while this may be acceptable for a personal website, if you are creating a corporate website, AI website production and publication should not be the end of the story. You must verify that the website is functioning properly through a Quality Assurance (QA) process. If you do not take sufficient time to refine the website, it may provide a negative experience for visiting customers and fail to appear in Google and AI search results.
Today, I will summarize a website optimization checklist that Elifunt actually uses, which allows you to self-diagnose for SEO/GEO optimization after AI website creation
What are the potential downsides of AI website creation?
If you are hesitant about creating an AI website due to a lack of development resources or the burden of outsourcing costs, you may have doubts about whether a corporate website built with Vibe Coding is actually usable for your business. In reality, the disadvantages of creating a corporate website using AI tools can be summarized into two main points.
First, it is difficult to differentiate the design, so we cannot preserve the brand identity
First, it is difficult to differentiate the design of websites created in a short period using AI tools. Just as text written with ChatGPT reads like "AI-generated text" due to its distinctive style, it is difficult to avoid the perception that a corporate website built with Vibe Coding is an "AI-made homepage." Considering that a homepage serves as the face of our organization's brand identity, a corporate website constructed solely with Vibe Coding can lower credibility.

Second, it is difficult to attract customers organically because SEO settings are difficult
Search Engine Optimization (SEO) is challenging for websites created with AI . The VIVE Coding platform either does not support SEO settings or requires manual optimization through a QA process.
In fact, among the clients who worked with Elifunt on website optimization, there were cases where SEO performance declined after creating corporate websites using AI tools. For example, they experienced problems like these.
😢 SEO problems encountered after AI website creation
- Meta tags are applied equally to all pages
- Since the URL structure does not support nested paths, the slug is inserted as a parameter
- Image alt tag and heading structure not optimized
- It is difficult to optimize performance and speed while using AI-generated high-resolution images as is
If you do not manage your corporate website from an SEO optimization perspective, it will not appear in Google or AI searches, and organic customer traffic will not occur. However, for non-SEO experts, it is not easy to determine, "Then what needs to be fixed?" To help even non-experts turn their corporate website into a business hub that drives customer traffic and conversions,we have compiled an essential checklist for website optimization.
17 Essential Checklist Items for Website Optimization
Crawling and Indexing
The first step is the crawling and indexing stage. Crawling is the process in which search engine bots visit a website, read pages, and collect information. If crawling is successful, the page information is stored and classified in the search engine database. This process is called indexing.
Our company website can only be discovered when users search for relevant keywords once indexing is complete. What process is required to complete crawling and indexing?
1. Has the sitemap been generated and submitted?
A sitemaprefers to a file that organizes all the core pages of a website in XML format. Simply put, a map that helps search engines efficiently find website pages. Please generate a sitemap using various tools (XML sitemaps ) and submit it to Google Search Console.

2. Is robots.txt properly configured?
robots.txt refers to a text file placed at the top level of a website. Its role is to inform crawlers (search engine bots) which URLs are allowed or not allowed to crawl. By defining the scope of allowed and blocked crawling, it also guides the location of sitemaps and prevents server overload by ensuring crawlers do not scrape too many unnecessary pages.
Please create a file named robots.txt, connect to an FTP program like FileZilla, and upload it to the top-level directory of your website.
3. Is llm.txt configured correctly?
While robots.txt targets search engine crawlers, llm.txt refers to providing a summarized guide to help AI models and agents quickly understand the site. It generally includes information such as an introduction to the site and brand, core category structure, representative URLs, and content policies.
llm.txt is a recent trend. Since there is no guarantee that all AIs will read llm.txt, it is still closer to an industry practice or experiment than an official standard.
4. Are there any pages with the noindex tag incorrectly set?
The noindex tag is a meta tag added to the head section of a homepage HTML page. a tag that instructs search engines not to display this page in search results.
, such as admin pages or pages shown after logging in, add the `noindex` tag and exclude them from the sitemap. If `noindex` pages are present in the sitemap, errors or warnings may appear in Google Search Console.
The noindex tag can be added to the HTML head section in the following format.
<!-- noindex 태그 예시 --><head> <meta name="robots" content="noindex"> <title>Pages that should not be displayed in search enginestitle></head>
5. Is the canonical tag set correctly?
A canonical tag is an HTML tag that identifies the original page when similar or duplicate content exists across multiple URLs. If there are multiple URLs leading to the same page, it is necessary to set up canonical tags because search engines may become confused about which URL to display in search results, potentially lowering search rankings.
The canonical tag can be added to the HTML head section in the following format.
<!-- canonical 태그 예시 --><head> <link rel="canonical" href="> <title>Original Page Titletitle></head>
6. Has the page been indexed?
You can check in Google Search Console whether your pages are actually indexed and being properly read by search engines. If they are not indexed, identify the reason and request manual indexing if necessary.

Increase page speed and performance
7. Do you meet the Core Web Vitals criteria?
Core Web Vital (CWV) is a key UX performance metric that Google uses to evaluate page quality. It is one of the signals that affects search rankings. You can check it in Google Search Console under [Experiments] – [Core Web Vital].

Methods to increase page speed while meeting core web vital metrics include image optimization, browser caching, CSS/JS compression and minipification, using CDNs, and removing unnecessary redirects.
Optimizing for mobile and browsers
Since 2024, Google has been ranking search results based on mobile versions. Search engine spiders first crawl a company's mobile content to determine the relevance of web pages, and then analyze the desktop versions.
Therefore, to optimize your website, you need to ensure that you are providing the best possible environment for users from a mobile perspective. For detailed instructions, please refer to the "Making a Mobile-Friendly Site" page provided by Google
Implementing Structured Data and Schemas
8. Has the schema markup been implemented?
Schema markup structured data added to a website's HTML to help search engines better understand the page content.
For example, if you have a website for a company called Elifunt, you can use structured data to clearly inform search engines about information such as industry, services, and FAQs. More details are easily summarized in the “Schema Markup” content
9. Have you implemented breadcrumb markup?

Breadcrumb markup is a navigation element that visually displays a user's current location within a website and aids in navigation. Since it is also displayed in search results, it can be advantageous from an SEO perspective.
URL Structure & Redirect
10. Is the website's URL structure SEO-friendly?
Creating a logical and systematic website URL structuremakes it easier for search engine crawlers to read. For example, a structure like the following can be considered an SEO-friendly URL.
<https://elifunt.kr/service/geo-consulting/>
The example URL maintains a hierarchical structure such as Main (elifunt.kr) → Category (/service) → Detail Page (/geo-consulting). It uses hyphens (-) and does not use underscores (_). It is also important to remove unnecessary parameter values (e.g., elifunt.kr/service/?category=geo-consulting), use lowercase letters, and ensure that the slash (/) at the end of the URL is consistent.
11. Have you completed the 301 redirect mapping?
On the web, 301 means that the page's address has been permanently changed. A redirect refers to automatically moving from one URL to another. In other words, the process of connecting browsers and search engines so that they can automatically find the new address when a changed address is clicked is called 301 redirect mapping.
While one or two redirects are simple, when dozens to hundreds change due to site redesigns or URL structure modifications, they are generally 'mapped' in the form of Excel or spreadsheets. Without 301 mapping, a 404 error occurs the moment a URL changes and a search result is clicked, which lowers SEO performance andcan cause rankings to drop as the page is perceived as having been deleted.
12. Are there any broken links (404 errors)?
A 404 error is an error message that appears when the web browser cannot find the requested page on the server. It can occur in situations such as when a page has been deleted or when the URL has been changed without a redirect.
If you have such broken links, search engine crawlers may view the site as poorly managed and lower its SEO ranking . You need to check the URLs causing 404 errors through the [Pages] menu in Google Search Console and take action.
13. Are there no isolated pages (orphan pages)?
An isolated page, as the name suggests, a page that is isolated due to the lack of internal links. It is a page that exists in a sitemap but stands out on its own because there is no link leading to it. If you want a page to appear in search results, you must add internal links to that page to other important pages.
Content & Metadata
If you have completed the search engine optimization settings for your entire website using the previous checklist, it is now time to optimize the content on each page. To build a strong foundation for SEO and GEO, please make sure to check the following items.
14. Does every page have a unique title tag?
A title tag is an HTML tag that defines a website's title andis displayed in search results and browser tabs. If the title contains search keywords, it is more likely to appear at the top of search results when those keywords are searched. Furthermore, since the title is the first thing users see, it must be attractive to generate clicks.
15. Is the meta description optimized?
A meta description is a short description that summarizes the page's content. It is displayed below the title in search results. Because it serves to inform users of the page's content in advance, it directly affects the click-through rate.
16. Is the title tag (h tag) correctly structured?

Heading tags consist of six levels, from H1 to H6. Heading tags structure content much like a book's table of contents. If you write them well so that the content is organized just by looking at the tags, search engines will understand the page structure, increasing the likelihood of ranking higher in relevant searches.
17. Does the image have alt text?
Alt text refers to alternative text that describes an image . Since Google cannot accurately identify images on its own, it uses alt text to understand their content. Therefore, adding alt text to images is advantageous for exposure in image search results. It is recommended to include alt text attributes on all images, and they should naturally incorporate search keywords within 125 characters
