On-site SEO refers to the practice of optimizing elements on a website, such as the content and HTML code, to improve its rankings in search engine results pages and attract more relevant traffic to the website.

These signals can help search engines determine the authority and credibility of a brand, and can positively impact search engine rankings.

3. Technical SEO

This includes tasks such as optimizing site load time, ensuring that robot.txt files are properly configured, and setting up redirects correctly.

Crawl Error Identification

These errors can include broken links, missing pages, and other issues that can negatively impact search engine visibility. By fixing crawl errors, website owners can improve their website's search engine rankings and overall visibility.

4. International SEO

International SEO improves your website's organic traffic from different areas and languages. If you want to succeed at international SEO, you must cater to your target market's cultural context and allow them to make transactions in their currency and language.

Use the right format for dates and times based on the place they are listed. If they have any worries, converse in their native tongue. International SEO aims to create a good online experience for your target audience.

5. Local SEO

Local SEO strategy for local businesses is one of the most important types of SEO as it helps the business become more visible in local search results on Google.

Local SEO helps businesses reach the local audience by analyzing their behavior through trillions of searches. If you use local SEO practices, then your local business has the opportunity to rank higher in the search results and the local map pack at the same time. This, in turn, helps grow your business and increase traffic to your website.

6. E-commerce SEO

E-commerce SEO is one of the best ways to get traffic by paid search, but the SEO costs are much less. It helps create your online store website to rank higher whenever someone searches for a product or service. 

It’s important to have your website appear in the SERPs; else, you’ll lose critical access to potential and qualified ecommerce customers. If the competitors' research, focus on homepage SEO, and website architecturing is done right, then ecommerce SEO can optimize your website to bring traffic and increase search volumes.

7. Content SEO

Another name in the list of types of SEO is Content SEO. It refers to creating unique content, be it writing, graphics, or videos, to structure your website, ranking it higher in SERPs.

Three things must be considered while working with content SEOs - copywriting, site structure, and keyword strategy. It’s very important to balance all three, as, without quality content, your website cannot stand in the search results. 

Moreover, it’s equally important to check the content after publishing as that before publishing. Keep track of how your content is performing. Make necessary changes, add new products, and apply several strategies to broaden the reach of your website. 

8. Mobile SEO

Mobile SEO is a term used to describe optimizing a site for search engines while simultaneously ensuring that it is viewable properly on devices like mobiles and tablets.

If a customer has a bad experience with a brand on their mobile phone, they may never return. If you want your clients to have the best possible experience, you need to apply this type of search engine optimization. It's important to ensure that your site's style, structure, and page speed don't make mobile users change their minds.

9. White-Hat SEO

When you hear someone say white-hat SEO, that means the SEO practices that are in-line with the terms and conditions of the major search engines, including Google. White-hat SEO improves your search engine ranking on the SERPs while regulating the integrity of your website with the search engine’s terms of service. 

White-hat SEO practices are the best way to create a successful website. Here are a few white-SEO practices that you must follow strictly:

• Use keyword-rich, descriptive meta-tags
• Provide quality services and content to the website’s visitors
• Make your website easy to navigate  

10. Black-Hat SEO

Black-hat SEO exploits weaknesses in Google's search algorithm to rank higher in its search results. Spammy or paid link-building strategies, keyword stuffing, cloaking, etc., are used to get ahead in search engine results. These practices give instant results, but they can impact your website negatively if detected by Google. Hence, it is advised to avoid black hat SEO. 

11. Gray-Hat SEO

It’s an SEO practice that’s riskier than white-hat SEO. That’s because the gray-hat SEO practices belong neither to the white-hat nor black-hat category as the terms and conditions regarding the issue are unclear.

However, using gray-hat SEO practices will not result in a site ban from search engines. In simpler terms, the material or content that you publish in accordance with the gray-hat SEO remains ill-defined. Knowing the gray-hat SEO practices can save your website from losing traffic as you will be well-aware of the negative consequences, which will help you adopt fair practices. 

12. Negative SEO

Negative SEO is an abhorrent and unethical sort of SEO practiced today. The goal of negative SEO is to lower your competitors' search rankings so that you can overtake them or gain an advantage over them.

Bad SEO techniques include breaking into someone's site and creating a suspiciously large number of low-quality links to it and publishing negative feedback or reviews about them on numerous internet forums and discussion boards, etc. A person caught doing bad SEO can lead to a variety of legal issues.
