Nobody can guarantee you first place on Google, and anyone who promises it is misleading you. What can be done is to give Google, and the people searching, good reasons to show you. That depends largely on your website.
What you control
- One page for each subject. If you offer three services, each deserves its own page, with a title and description that say clearly what it is.
- Your customers' words. Write the way they search, not the way you describe the business from the inside. Ask them how they found you.
- A fast site that works well on a phone. A lot of people search and decide on their phone.
- Addresses that do not change. If you change a page's address, tell whoever runs the site to redirect it, or you lose what it had earned.
- Google Search Console. It is free, shows what people search for before they reach your site and warns you about errors. It is also where the sitemap is submitted.
- Useful, truthful answers. Pages that answer the questions your customers ask usually work better than pages stuffed with keywords.
What you do not control
Google decides the order of the results, and you cannot choose it or buy it. A new site takes time to be discovered: expect weeks or months, not days. And competitors are already there.
If you serve customers in an area
Create a Google Business Profile. It is free and puts your business on maps and in local searches. If you do not receive customers on site, you can hide the address.
Promises that should make you wary
- “Guaranteed first place.”
- “Thousands of visits a week.”
- Bought links from other sites.
- Results without ever showing you what they changed on the site.
Where to start
Pick the most important page of your site and check whether its title and description say what you do, for whom and where. Then read Does your site need a blog to show up on Google? and How to tell whether a website is easy to use.
