If you are interested in monitoring your website’s search engine performance, setting up a Google Search Console will help you do just that. 

As part of your SEO checklist for new website, here are the steps you need to follow:

Create an Account on Google Search Console➡️Add Website Property➡️ Verify Website Ownership➡️Submit Sitemap ➡️Monitor Indexing and Performance

Getting Started Tips: 
  • Add Domain Property instead of URL Prefix (unless you want to track the performance of a specific URL, such as (‘www.wewantdesign.co/us).
  • You can use tools, such as Yoast SEO, to generate sitemaps and submit them to GSC. 
  • Once everything is set up, you can link GSC with Looker Studio and generate reports. You can add as many metrics as you want, and schedule to receive the reports daily or once a week. 

2. Create a Robots.txt File 

A robot.txt file gives instructions to crawlers about which sections of the website they should access and which ones not to access.

For example, if there are two ‘Contact Us’ pages, one with updated information and the other with old data. You wouldn’t want the latter to be indexed, as it would lead to confusion amongst your target audience. 

Open Text Editor ➡️Define User Agents ➡️Use Allow and Disallow Directives➡️ Add Sitemap Location

Once you have created a robot.txt file, upload it to the root directory of your website. This file would be accessible via /robots.txt.

8. Schema Markup

Before you begin writing your blogs or content for your landing page, keyword research is important. 

See what keywords your competitors are ranking on, and target ones that are relevant to your business offerings. 

If you are running a SaaS company, that’s similar to Salesforce, here’s how your keyword research would look like through Ahrefs. 

Pro Tip: Target the keywords that have a low ‘Keyword Difficulty’, this will make it easier for your business to rank on Google. 

2. Title Tags and Meta Descriptions

Write compelling and keyword-rich title tags and meta descriptions. 

The former should be under 60 characters, whereas the latter should be about 150 characters long.

3. Add Internal and External Links

Adding links to your website, both internal and external, is important if you want to ensure that it ranks on Google. 

If your blogs are linked to your Service page, it becomes easier for the user to navigate through your website. It helps streamline the user’s journey. 

Whereas, if you write a blog and quote different sources or industry experts, that’s called external linking. Any link that doesn’t redirect back to your website is classified as such. 

Pro Tip: When publishing, make sure that all the internal links are do-follow whereas all the external links are no-follow. You don’t want to give your traffic to your competitors. 

Off-Page SEO

Off-page SEO focuses on activities that take place outside your website. 

1. Outreach and Backlinks

It can help boost relationships with like-minded businesses. 

For backlinks, you can acquire them by answering journalist’s queries and requests. 

When reading your response to a query, the journalist will see you as an authoritative figure to comment on. And in exchange, would link your website to the blog they are writing. 

Pro Tip: To get relevant backlinks, use platforms such as Qwoted. You can see the journalist and magazine you’re pitching content to. 

2. Social Media Management
