How to choose a technical SEO tool
Updated Oct 9, 2026.
Start with Search Console
Google Search Console is “a free service offered by Google” (Google Search Console Help), and several of its reports check things a site audit tool also looks at: the Index coverage report lists the pages Google indexed or tried to index, the Core Web Vitals report shows how pages perform “based on real world usage data”, and the rich result reports show the structured data Google could or couldn’t read (Google Search Central). There’s no need to sign in every day, since Search Console emails you when Google finds new issues (Google Search Central). A crawler or audit tool earns its price when you need to check pages Google hasn’t reported on, or run checks Search Console doesn’t, across your whole site whenever you choose.
Know what your platform already handles
Shopify says every store handles canonical tags, a sitemap and a robots.txt file on its own (Shopify Help Center). For sitemaps, Google says that on a platform such as WordPress, Wix or Blogger, “it’s likely that your CMS has already made a sitemap available to search engines and you don’t have to do anything”, and that a small site, “about 500 pages or fewer”, may not need one if every important page can be reached through its menu or links and it doesn’t have many videos, images or news pages to show in search (Google Search Central). Before you pay a tool to add any of these, check what your platform already does.
Read duplicate content warnings calmly
If an audit lists duplicate pages, remember that Google says “Some duplicate content on a site is normal and it’s not a violation of Google’s spam policies”, and that a canonical tag is “a hint, not a rule”: Google picks one page from a set of duplicates and usually shows that one (Google Search Central). Google notes that duplicates can be a bad experience for visitors and can make it harder to track how your content performs, so tidy them up, but an ordinary duplicate isn’t a spam policy violation.
Measure speed the way Google does
Core Web Vitals “measure real-world user experience”, and Google’s targets are a Largest Contentful Paint within 2.5 seconds, an Interaction to Next Paint under 200 milliseconds and a Cumulative Layout Shift score under 0.1 (Google Search Central). Check whether a speed tool reports these from real visitors’ data or from a single test run of its own, and compare it with Search Console’s Core Web Vitals report.

Words to know
- 301 redirectA permanent server-side redirect from a page's old address to its new one, which Google takes as a signal to show the new address in search results.
- Canonical URLThe address Google treats as the main version of a page when the same content can be reached at more than one address.
- Core Web VitalsGoogle's three measures of how a page feels to real visitors: how fast its main content loads, how quickly it responds, and how stable it stays visually.
- Crawl budgetThe set of URLs on a site that Google can and wants to crawl; Google's guide to it is for large sites whose pages change often, and others don't need to read it.
- Crawlable linkA link Google can follow to find another page, which generally means an HTML a element with an href attribute pointing to a real web address.
- Duplicate contentThe same content reachable at more than one URL, such as HTTP and HTTPS copies or a category page's sorted and filtered versions.
- FaviconThe small square icon for a website that Google can show next to the site's results in Google Search.
- Google Search ConsoleGoogle's free service that shows site owners how their site does in Google Search, which searches show it, and the problems Google finds with it.
- hreflangAn annotation that tells Google which of your pages are versions of the same content for different languages or regions, so Search can show people the right one.
- HTTPSThe secure version of a web address, which Google strongly recommends for every site and prefers to index when a page has both an HTTP and an HTTPS address.
- Manual actionGoogle's action against a site when one of its reviewers finds pages that break Google's spam policies. Affected pages can rank lower or drop out of results.
- Meta descriptionA short summary of a page in its HTML, which Google may use as the snippet in a search result when it describes the page better than the page's own text.
- Mobile-first indexingGoogle's use of the mobile version of a site's content, crawled with its smartphone agent, to index and rank the site's pages.
- noindexA rule in a page's code or HTTP header that tells Google to leave the page out of its search results. Google has to be able to crawl the page to see it.
- Page experienceHow satisfying a page is to use, judged across many aspects such as loading speed, security, how it shows on phones, ads and pop-ups.
- robots.txtA file at the root of your site that tells search engine crawlers which addresses they may crawl. It manages crawler traffic; it doesn't keep a page out of Google.
- Site nameThe name of the website Google shows with each search result, chosen automatically for the whole site, separate from each page's title link.
- SitelinksExtra links to pages on the same site that Google sometimes groups under a search result, picked automatically from the site's link structure.
- SitemapA file that lists the pages and files on your site you think are important, so search engines can find and crawl them more efficiently.
- Soft 404 errorA URL that shows visitors a page saying it doesn't exist, or an empty page, while telling Google the request succeeded with a 200 status code.
- Title linkThe title of a result in Google Search, which links to the page. Google writes it automatically from sources such as the page's title element and main heading.
