What is website SEO optimization? How it works and why you should choose Viet SEO

(09:55:23 PM, 09/05/2025)
Website SEO optimization (Search Engine Optimization) is a set of techniques and strategies aimed at improving a website's visibility on search engines, especially Google—which holds over 90% of the global search market share.

What is website SEO optimization?

The goal of SEO optimization is to help a website appear in higher positions on search engine results pages (SERPs) when users enter keywords related to the business’s products, services, or industry. This helps increase access to potential customers naturally and sustainably, without relying too heavily on paid advertising.

  • Technical SEO
  • On-page SEO
  • Off-page SEO
  • Improving user experience (UX)
  • Increasing page load speed and mobile visibility
  • Ensuring the website is easy to crawl and index by search engine bots

The ultimate goal is to improve rankings, increase organic traffic, attract potential customers, and boost conversion rates.

Main goals of website SEO optimization

SEO optimization is not just about “ranking on Google.” It is a long-term marketing strategy with several specific goals:

1. Improve visibility on Google

Helps your website appear in top positions when customers search for keywords related to your product/service.

2. Increase organic traffic

SEO generates sustainable traffic without paying for each click like PPC ads.

3. Enhance brand credibility and reputation

Websites in top search results are often perceived as more trustworthy by users.

4. Optimize user experience

SEO requires improvements in structure, speed, and mobile compatibility—helping retain visitors longer.

5. Increase revenue

The final goal of SEO is to convert traffic into customers, increasing conversion rates and sales.

How does SEO optimization differ for new vs. old websites?

Depending on the age and current state of a website, SEO strategies will differ significantly.

SEO for new websites

New websites often have no domain authority, traffic, or backlinks. Therefore, the focus should be on:

  • Keyword research suitable for the early stage
  • Clear website structure that’s easy to crawl
  • Optimizing speed and mobile version
  • Writing unique, high-quality content
  • Using internal links strategically
  • Registering with Google Search Console and creating an XML sitemap

Note: In the early phase, you should target low-competition niche keywords to rank faster.

SEO for older websites

Long-standing websites usually have backlinks, content, and rankings—but also potential issues:

  • Outdated content that needs updating
  • Broken or spammy backlinks that need fixing
  • UI/UX no longer aligned with modern standards
  • Illogical website structure
  • Slow loading speed, failing Core Web Vitals

At this point, a full website audit is necessary, followed by improvements based on real data from Google Analytics, Search Console, and professional SEO tools.

What to do when a website is penalized or downgraded by Google?

Some signs that your site may be penalized or downgraded by Google include:

  • Sudden drop in keyword rankings
  • Deindexing of multiple pages
  • Significant decline in organic traffic
  • Severe errors reported in Google Search Console
  • Unexpectedly slow page loading time

Common causes:

  • Low-quality or spammy backlinks
  • Duplicate or plagiarized content
  • Keyword stuffing or over-optimization
  • Lack of HTTPS security
  • Poor user experience

Steps to fix:

  1. Manually check Google Search Console for penalty notifications
  2. Perform a full SEO audit: backlinks, content, technical issues
  3. Disavow toxic backlinks (if necessary)
  4. Update or remove duplicate or low-quality content
  5. Optimize speed, design, and website structure
  6. Submit a reconsideration request to Google if there's a manual penalty

Fixing SEO penalties takes time, expertise, and proper methodology—so it's best to work with a professional SEO agency to ensure effective recovery.
