How to Check SEO Items on a Webpage
Why Page-Level Inspection Still Matters
Site-wide audits are useful, but rankings are won page by page. When a specific page underperforms — plenty of impressions and no clicks, or no visibility at all — you need a systematic way to inspect exactly what that page is telling search engines. Working from a repeatable checklist removes guesswork and surfaces problems that dashboards summarise away.
The good news is that almost everything you need is free. Your browser's developer tools, view-source, Google Search Console and a handful of free testing utilities will reveal the vast majority of page-level issues without any paid subscription.
How We Turn Page Audits Into Ranking Gains
Finding issues is the easy half; knowing which ones actually affect performance and fixing them correctly is where results come from. At AAMAX.CO we audit pages against commercial priorities, separate cosmetic warnings from genuine blockers, and implement the fixes directly in your site. If you would rather have specialists diagnose and resolve the problems instead of working through tool reports yourself, hire AAMAX.CO for hands-on SEO services. We are a full service digital marketing company delivering web development, digital marketing and optimisation worldwide, so audit findings become shipped improvements rather than a document nobody actions.
Check the Metadata First
Open the page source and inspect the head section. Confirm there is exactly one title tag, that it is unique across your site, that it leads with the page's primary topic and that it is short enough to display without truncation. Confirm there is one meta description, written as persuasive plain text of roughly 140 to 160 characters, with no markup inside it.
Then look for the canonical tag. It should point at the page's own preferred URL using the canonical hostname and protocol. A canonical pointing somewhere unexpected is one of the most common causes of a page vanishing from search results. Check the robots meta tag too — an accidental noindex left over from staging will keep the page invisible no matter how good the content is.
Review Headings and Content Structure
Use your browser's accessibility or elements panel to view the heading outline. There should be a single main heading that clearly states what the page is about, followed by subheadings in logical order that break the content into scannable sections. Headings should describe content, not be used purely for visual styling.
Assess the content itself against search intent. Read the top-ranking results for your target query and ask whether your page answers the question as directly and completely. Look for thin sections, duplicated boilerplate repeated across many pages, and padding that delays the answer. Confirm the primary keyword and its natural variations appear in the opening paragraph, in at least one subheading and throughout the body without awkward repetition.
Inspect Links, Internal and External
Check that the page has meaningful internal links pointing out to related pages, using descriptive anchor text rather than generic phrases. Just as importantly, check that other relevant pages on your site link into it — an orphaned page with no internal links is hard for crawlers to value and easy for them to overlook.
Verify no links return errors or pass through unnecessary redirects. Review outbound links for relevance and quality, and confirm that any sponsored or user-generated links carry the appropriate attributes.
Audit Images and Media
For every meaningful image, confirm there is descriptive alt text. Decorative images should have empty alt attributes so screen readers skip them. Check file sizes: an uncompressed hero image is the single most common cause of poor loading performance. Confirm images are served in modern formats, sized appropriately for their display dimensions, and that below-the-fold media is lazy loaded while the main above-the-fold image is not.
Also confirm images have explicit dimensions or aspect ratios so the layout does not shift as they load, since visual instability is measured and penalised.
Confirm Indexability and Crawlability
Use the URL Inspection tool in Google Search Console for the definitive answer on how the page is treated. It tells you whether the URL is indexed, which canonical the search engine selected versus the one you declared, when it was last crawled, and whether any issues were detected. If the declared and selected canonicals disagree, that discrepancy is your priority.
Check robots.txt is not blocking the page or the resources it needs to render, and confirm the URL appears in your XML sitemap. Verify the page returns a 200 status code and does not sit behind a chain of redirects.
Validate Structured Data and Rendering
Run the page through a rich results test to confirm any structured data is valid and eligible for enhanced display. Check that the markup accurately describes visible page content — mismatched structured data can lead to manual actions.
If your site relies on JavaScript to render content, compare the initial HTML response with the fully rendered DOM. Anything critical that exists only after script execution is at risk. Confirm your main content, metadata and links are present in the server response wherever possible.
Measure Performance and Mobile Experience
Test the page with a performance tool and review field data as well as lab scores. Focus on how quickly the largest visible element renders, how responsive the page is to the first interaction, and whether layout shifts during load. Then open the page on an actual phone and use it. Tap targets that are too small, text that requires zooming, intrusive interstitials and horizontal scrolling all damage both experience and rankings.
Build It Into a Routine
Turn this sequence into a checklist you run on every new page before publishing and on any existing page that underperforms. Prioritise findings by impact: indexability blockers first, then content and intent alignment, then metadata and internal links, then performance refinements, then cosmetic warnings.
Conclusion
Checking the SEO items on a webpage is fundamentally about verifying that what you intended to communicate is what search engines actually receive. Work through metadata, headings, content, links, images, indexability, structured data and performance in a consistent order and you will catch the issues that matter long before they cost you traffic. If you would like an expert audit with the fixes implemented for you as part of a wider digital marketing plan, our team is ready to help.
