What Is SEO Analysis?

An SEO analysis involves evaluating your website to identify ways to improve your performance in organic (unpaid) search engine results, which can lead to more traffic and better business results.

It involves studying your content, your site’s technical health, competitors' sites, and more. Because these can all affect how search engines like Google rank (order) search results.

Like this:

organic results are numbered 1, 2, 3 with a people also ask serp feature between results 1 and 2

Types of SEO Analyses

Many website elements can impact your SEO performance. So, doing different types of analyses can help you narrow in on the most pressing issues.

Below are the main types.

Technical SEO Analysis

Technical SEO involves optimizing the technical aspects of your website. And the corresponding analysis is mainly focused on ensuring you don’t have any issues that could prevent search engines from crawling (finding) and indexing (storing in a database) your content.

Some of the main issues you’ll look for are those related to your:

The fastest way to check your site’s technical SEO is to use our free website audit tool. We’ll show you how to do so later in this article.

On-Page SEO Analysis

An on page SEO analysis entails evaluating your individual webpages to make sure they’re as search engine-friendly as possible and include the target keywords you want those pages to rank for.

On site elements to optimize include:

We’ll go over how to uncover issues related to these elements later in this guide.

Backlinks are links on other websites that point to your website. They’re an important factor that Google uses for organic rankings, so you’ll want to evaluate the number and quality of links coming to your site.

How a backlink works: An external link from one site pointing to another website.

But not all backlinks help your SEO that much. The best ones come from sites that are topically relevant to yours and have strong website authority (which can be checked using our free Website Authority Checker).

This type of analysis involves evaluating your backlink profile for:

It can also be useful to compare the above backlink factors against your competitors’ sites. So, we’ll cover how to do so later in this guide.

SEO Competitive Analysis

This type of analysis involves comparing your website’s SEO performance against your competitors’ performance. And can help you identify what it will take to compete with them.

A competitive analysis often involves comparing yourself against rivals for the following:

We’ll show you how to do this type of analysis later in this guide.

How to Analyze Your Website’s SEO Performance

Follow the below steps to perform a complete analysis of your website’s SEO.

1. Analyze Your Technical SEO

It’s best to start by analyzing your site’s technical SEO. Because technical elements impact the ranking potential of all of your webpages.

Get a fast technical read on a URL with our free SEO check. To analyze technical SEO across your full site, use Semrush Site Audit.

Start by entering your homepage URL into the text bar. Then, click “Start Audit.”

Follow the prompts to configure your audit.

Once your audit is ready, find the “Crawlability” section and click “View details.”

crawlability report highlighted

The report will help you evaluate how easily Google can crawl and index your important pages.

For example, locate the “Crawl Budget Waste,” section. It details where you’re wasting crawl budget. Which is the number of pages that Google is willing to crawl on your site in a specific period.

crawl budget waste shows most waste comes from permanent redirects, large page size, and pages blocked from crawling

You want to be careful about things like having too many pages that serve errors or too many redirects. Because if you have many issues like these, Google might move on before it gets to all your important pages.

If you click on the orange bar to the right of an issue. You’ll see a list of the pages affected by that specific issue.

list of page urls with too large html file size

Next, return to the “Overview” tab. Then, click “View details” under “Site Performance.”

This section will list any issues related to your site’s page load speed and other performance indicators.

Page experience is a confirmed ranking factor. So, it’s important to resolve related problems like slow speed.

Plus, performance issues are bad for the user experience. And may discourage people from staying on your website, making purchases, or booking appointments.

Improving site performance may require changes to your HTML or JavaScript files. So, depending on your level of knowledge, you may want to work with a web developer to resolve them.

2. Analyze Your On-Page SEO

Next, do an on-page analysis to find ways to improve your most important webpages—improving these existing ones can be a more cost-effective way to improve performance than creating new content.

So, review the below website elements on each page you want to rank for.

Title Tags and Meta Descriptions

The title tag and meta description of a webpage tell users and search engines what your content is about. And Google may display them to users when showing your pages in search engine results.

Like this:

title tag is the blue hyperlink text in the search engine results page and the meta description appears below the title tag

Google uses the title tag to understand a webpage’s content. And both the title tag and meta description can influence whether users click through to your page.

To check them, click on the “Issues,” tab in Site Audit.

Then, click the “Category” drop-down menu and select “Meta tags.”

meta tags selected from the category drop down

If any critical issues are identified, the report will list them.

meta tag issues include duplicate title tags and meta description, pages without alt attributes, and character count issues

Site Audit checks your title tags and meta descriptions for the following errors:

To get more details about a specific issue, click on the blue text at the beginning of the row.

You’ll see additional details about the issue. Like what pages the issue was identified on.

page urls with too much text within the title tags

Make sure to review these issues. And work to resolve them.

Content Structure

Headings are HTML tags ranging from H1-H6 that define headings on a webpage and help Google understand what topics your content covers.

the h1 is for the main topic. h2 for the subtopic. h3 for the sub-subtopic

Headings also give your content structure and make it easier to navigate. Because they can help users quickly scan to find the information they’re looking for.

To check for problems related to your H1 headings, return to the “Issues” tab in Site Audit. And enter “h1” in the search bar.

search for h1 in site audit shows issues like pages without an h1 heading or title tags

Site Audit checks for the following:

Again, click on the blue text next to any issue to get more details about the pages where it was detected. And work to fix the problems.

Keyword Use and Content Quality

Next, evaluate your content’s quality and how well your pages incorporate your target keywords. Because writing useful content that includes keywords naturally (without keyword stuffing) is key for on-page SEO.

Use On Page SEO Checker for this.

Enter your homepage URL into the text bar and click “Get Ideas.”

url entered into tool

Follow the prompts to finish the setup, then the tool will show a detailed report with ideas for improvement.

Click “# ideas” next to a page you want to analyze.

number of ideas highlighted

On the next page, scroll to the “Content” section. And study the details about your page’s readability and keyword use to determine what sorts of improvements you need to make. Like using target keywords in the <body> tag.

according to this website seo analysis, this url could use target keywords in the body tag to improve performance

Repeat this process for all your pages. And work through the suggestions.

Now, you’re ready to update your content.

In addition to what On Page SEO Checker flagged, make sure to use your keyword and any variations in different headings.

You should also ensure that your content is high-quality, helpful, and people-focused. Which you can do by:

Internal links help Google discover and index your pages, so you should check that there are no issues with them.

To do this, return to your “Overview” report in Site Audit.

Click “View details” under “Internal Linking.”

internal linking report highlighted

You’ll see a percentage score for your overall internal link health. As well as a list of issues related to internal links. The most impactful ones will be listed under the “Errors” section.

internal link issues include broken internal and external links, too long link urls, and page crawl depth more than 3 clicks

Some examples of issues the tool will flag include:

To resolve these issues, you’ll need to make adjustments to your links inside your content management system (CMS) or other website platform.

If you’re unsure of how to fix something, click “Why and how to fix it” next to any issue to get directions.

why and how to fix it pop up explains more about broken internal links and how to fix this issue

Linking issues tend to happen over time as your website grows. But if you have a newer website, it’s more likely to suffer from too few internal links.

So, find ways to add them by following these best practices:

Because backlinks are so important for rankings, you should check them when analyzing your website’s SEO. And you can use Backlink Audit to do that.

Type your homepage URL into the first text bar. Then, name your project (if desired), and click “Create project.”

(If you’ve already created a project for your website, find it and click on it when you open the tool.)

domain entered into tool

You’ll get a detailed report about your website’s backlink profile. Which shows your website’s Toxicity Score.

this site has a high toxicity score

You want your backlink profile to have a “Low” toxicity score. If yours is “Medium” or “High,” that’s a good sign you should work to gain more high-quality, relevant backlinks.

And you can find backlink opportunities using the Backlinks tool.

To start, enter a competing domain and click “Analyze.” When the report loads, click “Indexed Pages” and select “Broken Pages.” You’ll get a list of pages that don’t work properly.

Indexed Pages report on the Backlinks tool with "Broken Pages" selected showing a list of pages that don't work properly.

Look for a page similar to ones you already have or one you can create and click its number of backlinks.

Broken Pages on the Backlinks tool with "1,871" in the "Backlinks" column next a URL clicked.

This report shows all of the backlinks currently pointing to the broken page.

Find the best backlink opportunities by selecting “Best” to filter backlinks with a follow attribute.

The "Best" backlink opportunities on the Backlink tool showing a list of broken, do-follow competitor backlinks.

Look for relevant, high-quality sites. When you find one, send an email asking if they can link to your working resource instead of the broken one.

Here’s a template you can use in your link building outreach:

Subject: Quick question about your [topic] article

Hi [Name],

I was reading your article on [specific topic] while researching [related subject], and I noticed that the link to [broken resource/page name] in your section about [relevant section] appears to be broken.

I thought I’d let you know so you can keep your resource up to date.

I recently published a [type of content] about [your topic] that covers [unique value proposition: original research, updated information, comprehensive guide, etc.]. If you’re looking for a replacement, it may be a helpful alternative for your readers:

[URL]

Either way, thanks for creating such a useful resource. I hope this helps you keep the page updated!

Best,
[Your name]

5. Evaluate Yourself Against Your Competitors

Next, compare your keywords and backlinks to your competitors’ to complete an SEO competitive analysis that can help you uncover insights you might be able to use in your SEO strategy.

Some of the resulting actions might include optimizing for the same keywords, creating similar content, or reaching out to your competitors’ referring domains for link building opportunities.

To analyze a competitor’s keywords, use Keyword Gap.

Enter your domain and up to four competitors’ domains. Then, select your target location and click “Compare.”

domain and competitor entered into tool

In the keyword comparison report, look for the “Top Opportunities” table.

Select the “Missing” tab. Then, click “View details.”

top opportunities highlighted

You’ll see a table of keywords that your competitors are ranking for but your website isn’t.

missing keywords table shows the keyword, search intent, volume, difficulty, and more

You may want to target some of these keywords with your website content. As long as they’re relevant to what your business offers.

Next, analyze your competitors' backlinks using the backlinks checker.

Enter a competitor’s domain into the text bar. Then, click “Analyze.”

competitor url entered into tool

You’ll get key metrics related to their backlinks. Like what websites are linking to them, how reputable those sites are, and what anchor text the websites use to link to your competitor’s site.

backlink overview report shows this domain's authority score, number of referring domains, and more

Then, leverage that information in your link building efforts.
