A Step-by-Step Guide to Learning On-Page SEO

Here are the 5 quick and easy to follow guides that tell you what to do when to do and how to do in your on page seo process.  

Step 1: Use SEMrush to do a site audit.

According to the RankMarket, “ 70% of SEO problems are caused by things on the page. That’s why an audit is a very important first step.

First, find out how well your website’s SEO is doing right now.

  • Go to SEMrush and click on Site Audit.
  • Do a full check of your domain
  • Pay attention to the following:
    • Links that don’t work (404 errors)
    • Missing meta descriptions or title tags that are the same
    • Pages are taking so much time in loading
    • Problems with mobile usability
    • Missing alt tags

Step 2: Use SEMrush to find keywords

The first step to good on-page SEO is to choose the right keywords. You can use SEMrush’s Keyword Magic Tool. 

Search for:

  • A lot of searches
  • Keyword difficulty is low to medium.
  • Search intent that is relevant
  • Find the main and secondary keywords for each page.

For example, the main keyword is “best running shoes for flat feet.” then your secondary keywords should be “running shoes for arch support” and “flat foot running gear”. 

Tip: To make content that ranks for more than one term, group related keywords into topic clusters.

Step 3: Make the structure of your content better

Use the keywords to make the most important parts of your page better:

ElementBest Practice
Title TagKeep it short, no more than 60 characters, and use your main keyword.
Meta Description155–160 characters, interesting, and includes the keyword.
Headers (H1–H3)Put content in a hierarchy and use keywords
URLshort, easy to read, and full of keywords
ImagesCompressed for speed, with alt text that describes it
Internal LinksUse anchor text that is full of keywords to link to relevant internal pages.

You can also use SEMrush’s On-Page SEO Checker. This will tell you how well your pages are optimized for your target keywords and give you suggestions for how to make them better.

Step 4: Use GA4 to keep an eye on how users act

If your page is getting traffic but people are leaving it without taking any action, then you need to find the reason. Use GA4 to see how people interact with your content. It might not be what users want or it might not have clear next steps. So, at this point you need to optimize it for your users. 

To check the performance of your web page follow the path: 

Go to GA4 > Pages and Screens > Engagement

Then keep an eye on these vital metrics from GA4 on your website:

  • Average engagement time: Are people spending time on your page?
  • Bounce rate: Are people leaving without doing anything?
  • Conversions: Are your calls to action working?

Thus, you will understand your users’ behaviour with your website and make essential changes from time to time. 

Step 5: Keep getting better with both tools.

SEO isn’t something you do once; it’s something you do all the time. So once you apply the above mentioned 4 steps, you need to track it. 

  • Firstly, use SEMrush Position Tracking to keep an eye on how the keyword rankings of your web pages change over time.
  • You can see how organic traffic trends change by looking at GA4 Traffic Acquisition reports.
  • To keep your site clean and working well, do SEO health checks once a month.
