Let's start with the concept of SEO services first. What are the SEO services are mainly of two types:
1. Optimization on the page:
Includes any change related to SEO on that website. Development of content for the website, change of meta tags, canonicalization, redirection, URL structuring, SEO writing, keyword analysis, competition analysis, coding and more.

2. Page Optimization:
Any SEO work outside the site is known as page optimization. The emphasis is on creating backlinks. Many say the largest search engine in the United States. UU. Namely, Google places the greatest emphasis on factors outside the page. You may have heard of link building. They say it is the most important factor for optimizing off-page. According to unconfirmed sources, I've been told that Google gives a weight of 60% to outside factors. Send folders, submit articles, send RSS, create reciprocal links, create links with 3, 4 and more links, etc. One day another site is also included in Off Page SEO and is Social Media Optimization (SMO). Social networks consist of social bookmarks and social networks. Facebook, Twitter, Hubpages, Stumbleupon, Yahoo Answers are just a few names in this huge world of SMO. Stumbleupon and Digg are the most popular in the bookmarks section. Facebook, Twitter and other websites that make friends are social networks.
All SEO companies are not experts in all of the above services. It has been observed that some of the companies are good at work on the site, but they are not as good at off-page works and vice versa. Some are also good at building links, but not for Social Media Marketing or SMO. Therefore, the company that provides a comprehensive solution to your SEO needs is considered the best SEO provider.

Another aspect is very important in the SE optimization work and is the creation of the website card. Site maps can be created on the website or blog. It helps visitors find a page very easily. It helps them navigate in a clear way. It's not all. These site maps also help robots/search engine robots navigate in a clear way. The creation of sitemap.xml is also there. Many companies do not offer these services to their customers. Therefore, it is one of the very important criteria for choosing the best SEO provider company.
