A technical SEO audit reveals what\u2019s preventing Google from finding, understanding, and ranking your website well. For larger companies, this is rarely a single issue. Rather, it\u2019s a collection of many small problems that have accumulated over the years: old subpages, campaign pages, plugin remnants, and unfinished translations.<\/p>\n\n\n\n
Below, we'll go over what we review during an audit and what issues typically come to light.<\/p>\n\n\n\n
SEO plugins are useful: they help fill in the title and meta description, and generate a sitemap. However, they don\u2019t detect that the homepage loads 8 MB on mobile devices, that the robots.txt file isn\u2019t even accessible due to a server rule, or that the English pages have Hungarian canonical tags. These errors are in the code and server settings, not in the editor interface.<\/p>\n\n\n\n
We\u2019ll check what Google sees: whether the robots.txt file is accessible, what the sitemap contains, and whether it includes any pages that shouldn\u2019t be there (such as a thank-you page or a duplicate archive). We\u2019ll check the noindex and canonical settings, 404 pages, and redirect chains.<\/p>\n\n\n\n
Google looks at three metrics: the loading time of the largest contentful paint (LCP\u2014ideally under 2.5 seconds), the initial input delay (INP\u2014under 200 ms), and the cumulative layout shift (CLS\u2014under 0.1). We measure these on mobile devices because rankings are based on the mobile view. Meanwhile, we look for what\u2019s weighing down the page: videos, unoptimized images, JavaScript libraries loaded twice, and full icon fonts just for a few icons.<\/p>\n\n\n\n
On our own website, for example, by re-encoding the hero and reference videos and removing unnecessary scripts, the download size of the home page was reduced by roughly half, while the visual experience remained the same.<\/p>\n\n\n\n
One H1 per page, a logical H2\u2013H3 hierarchy, and internal links that direct both visitors and search engine crawlers to important pages. On larger sites, it\u2019s common for service pages to have almost no links pointing to them, since all the links are in the menu.<\/p>\n\n\n\n
If the site is available in multiple languages, check to make sure that the language versions link to each other correctly and that the English page isn't ranking for Hungarian search queries. We'll also review the machine-translated titles and descriptions, since these appear in the search results.<\/p>\n\n\n\n
Organization, Service, FAQPage, Article, BreadcrumbList: These help Google better understand who is behind the page and what it offers. We\u2019ll check to see if the schema matches the visible content, because Google ignores any discrepancies.<\/p>\n\n\n\n
Are Search Console, GA4, and ad pixels working properly, and is cookie consent being handled correctly? An audit is only valuable if we can measure the impact of the fixes afterward.<\/p>\n\n\n\n
The most common issues: duplicate content (the same article on multiple pages or domains), missing or duplicate title tags and meta descriptions, content types omitted from the sitemap, heavy media files, and tracking codes that run twice or not at all. Individually, these may seem minor. Taken together, however, they\u2019re enough to allow a competitor with weaker content to rank higher.<\/p>\n\n\n\n
This is where things usually get stuck. The SEO specialist hands over the list, the developer doesn\u2019t have the resources to address it, and the marketing team is busy with campaigns in the meantime. That\u2019s why we assess and fix the issues as part of the same team, and we measure results both before and after the fixes to see what impact they\u2019ve had.<\/p>\n\n\n\n
