Start your analysis with the blue captures; the green 3xx redirects help you spot a migration. - A missing snapshot doesn't prove there is no history, and the Wayback Machine is not a substitute for a backup. The Changes, Summary, Site Map and URLs tabs help you find the moment of change and recover old addresses. - In SEO, the archive is used to explain traffic drops, recover old URLs for 301 redirects after a migration, and assess a domain before buying it. You combine it with registration data (RDAP), the link profile and visibility. The easiest way to check a website's history is the Wayback Machine ([web.archive.org](https://web.archive.org)), an archive run by the Internet Archive. Enter the site's address, pick a date in the calendar and open the saved snapshot. The tool is free and shows archived versions of pages going back as far as 30 years. It's worth doing, because the site you see today often bears little resemblance to the version from a few years ago. Content, URLs, category structure, design, the offer and internal linking change, and sometimes so do the domain's owner and the whole nature of the business. If you're analysing an older domain, preparing a migration or looking for the cause of a drop in Google visibility, the current version of the site alone shows you only a fragment of the history. That's why it's worth combining the archive with the domain's registration data, changes in organic visibility and the link profile. Only by combining these sources can you answer not just “what did this site once look like?” but also “what changed on the site and what effect could it have had on SEO?”. This guide takes you through the whole process: from finding the first snapshot in the Wayback Machine, through analysing old URLs and redirects, to checking a domain before you buy it. ## Website history vs domain history: how do they differ? When you check a website's history, you're mainly analysing what was at a given address at a given moment. You're interested in earlier versions of the homepage, service pages, categories, articles, menus or the whole structure of the site. This lets you see whether the company changed its offer, removed important content, moved its blog, rebuilt its information architecture or migrated to new URLs. Domain history is a different level. You check, among other things, the date of registration, the data available in the registry, earlier use of the domain, DNS changes and its past from an [SEO](https://justidea.agency/en/services/marketing-agency/positioning-seo/) perspective. An important part of such an analysis is also the link profile and historical visibility in search. In 2026, when analysing registration data, it's worth talking about RDAP rather than treating WHOIS as the current standard for gTLD domains. [ICANN designates RDAP](https://www.icann.org/en/announcements/details/icann-update-launching-rdap-sunsetting-whois-27-01-2025-en) as the primary source of current registration information for these domains from 28 January 2025. The ICANN requirement does not, however, cover country-code domains such as .pl, which are managed by NASK (the Polish domain registry). You can check .pl domain data in the WHOIS database at dns.pl or in the [RDAP that NASK launched in March 2025](https://dns.pl/newsy/RDAP-nowosc-w-NASK). It's worth going straight to the registry, because some external search tools don't show data for .pl domains. Remember that simply checking the registry won't show you the full history of previous owners. If you need historical registration data, you have to use services that archived it earlier. This distinction matters a lot in SEO. A domain may have existed for a dozen or so years, but for most of that time pointed to a completely different site. It may also have a long history of links that you won't see by looking only at the current site. ## How to check a website's history in the Wayback Machine, step by step 1. Go to web.archive.org. 2. Enter the full address of the site or a specific page and confirm the search. 3. On the timeline, pick the year you want to analyse. 4. In the calendar, click a capture date, preferably one marked blue (a correctly returned page). 5. Choose the snapshot time and open the archived version of the page. 6. When browsing subpages, check the date in the Wayback Machine bar, because the archive may open captures from other days. Below I go through each step and show the features that help with a more detailed analysis. ### Searching for an address and URL variants: www, http and https Start by entering the full address of the site in the Wayback Machine search box. If you don't find the results you expect, check the different historical variants of the address. In the past, the domain may have worked under different address variants: with and without www, under http and later under https. For a modern browser these may be variants that ultimately lead to the same place, but in the archive each address may have been saved separately. This rule is especially important for old domains and sites that have been through several migrations. If you check only the current URL and see few snapshots, don't end the analysis there. Also search for older variants of the domain and the addresses of specific pages. ### The calendar and snapshot colours After you search for a URL, you'll see a timeline and a calendar. The number and size of the markers show when the address was captured. A large number of snapshots doesn't mean, however, that the page's content changed as often. The colours have specific meanings. Blue markers refer to 2xx responses, which includes a correctly returned page. Green means 3xx redirects, orange means client-side errors in the 4xx group, and red means 5xx server errors. [The Internet Archive recommends](https://archivesupport.zendesk.com/hc/en-us/articles/360004651732-Using-The-Wayback-Machine) starting a typical analysis with the blue captures. For an SEO specialist, though, green snapshots are just as interesting. If a series of 3xx responses suddenly appears on the timeline, you may catch the moment of a migration, a protocol change or a redirect of an old address. ### Browsing subpages and HTML code Once you open a snapshot, you can move around the saved site much like an ordinary website. It's a good way to find old navigation, product categories, blog posts, offer pages and internal links. During this kind of analysis, though, keep checking the date shown in the Wayback Machine bar. If the archive doesn't have a given page from the same day, it may open the nearest available version. When a resource isn't in the archive at all, the link may in some situations lead to the version currently on the web. As a result, in a single session you may unknowingly be looking at resources from different moments. You can also inspect the HTML and saved resources, but don't treat the code displayed by the archive as a perfect copy of the original site. The Wayback Machine modifies some addresses in order to reconstruct the archived version of the page, and missing scripts and external resources can change how the site works. ### How to save a page yourself with Save Page Now The Wayback Machine doesn't visit pages automatically just when you need it to. If you want to preserve the current state of a specific URL, you can use the **Save Page Now** feature. You enter the page address, start the capture and get a link to the snapshot that was created. The feature is useful before a major change to the site, a migration, the release of a new version of the site or an update to an important document. Remember one limitation: basic Save Page Now saves a specific page, not the whole site, a directory or all the addresses in the domain. The Internet Archive states this explicitly in the [Save Page Now documentation](https://archivesupport.zendesk.com/hc/en-us/articles/360001513491-Save-Pages-in-the-Wayback-Machine). ## Advanced Wayback Machine features If you use the Wayback Machine only through the calendar, you're using just part of the tool's capabilities. Above the timeline you'll find additional tabs, including **Changes, Summary, Site Map and URLs**. ### Changes: find the moment of actual change The Changes tab helps you compare two snapshots of the same URL. You pick two dates, and the tool sets the saved versions side by side and highlights the differences. In SEO you'll use this feature mainly when you know roughly when traffic dropped but don't know what changed on the site. Instead of opening a dozen snapshots by hand, you can narrow down the period in which the content was rebuilt, a section was removed or the page layout changed. ### Summary: see the archive from the data side This tab shows a breakdown of the types of saved files (e.g. HTML, images, CSS) and their numbers year by year. This lets you quickly judge whether the archive contains enough material to reconstruct the structure of an old site. ### Site Map: reconstruct the old structure Site Map visualises the resources saved for a domain in a chosen period. For large sites, it lets you quickly get a sense of how extensive the structure was and which directories contained the most addresses. If you're analysing a migration, don't look only at the old homepage. The map can lead you to sections that the current site no longer has. ### URLs: one of the most valuable features for a migration The URLs tab shows the resource addresses the archive found for the site you're analysing. For larger domains the list can be very long, but that's exactly why it's valuable: it lets you discover URLs you wouldn't learn about from the current menu. If the previous migration was done without a complete redirect map, the list of historical URLs can help you find old categories, products, articles or landing pages. ## How to use a website's history in SEO A website's history isn't just for looking at old layouts. In an audit, it can become an extra source of data that explains problems not visible in the current version of the site. ### SEO audit and explaining traffic drops In Google Search Console you see a sharp drop in clicks from a particular month, and the current site works correctly from a technical point of view. A crawl alone therefore doesn't explain the cause. In that case, open a snapshot from before the drop and the first capture after it. Compare the menu structure, the content of the most important landing pages, headings, the presence of text sections and internal linking. If the change coincides with a site rebuild, you have a starting point for further analysis. The Wayback Machine doesn't prove on its own a causal link between a change and an SEO drop. It does let you establish what changed and when, and you can combine that information with GSC, GA4, Ahrefs, Semrush or server logs. ### Recovering old URLs and 301 redirects after a migration In a site migration, one of the biggest problems is the lack of a complete list of old addresses. If some pages have already been removed, you won't find them in a current crawl. This is where the archive helps, and I show the whole process in the example below. Don't automatically redirect every old URL to the homepage. Recreate the topical relationship and send the user to the most relevant equivalent. That way you keep a logical path for both visitors and bots. ### Recovering deleted content The Wayback Machine can save the day when a valuable guide, category description or landing page was deleted without a copy. If you find a preserved version, don't copy it mechanically to the new site. Check that the information is still current, along with search intent, the offer and product data. Treat the archive as source material, not ready-made content to paste in. ### Competitor analysis and UX changes A competitor's site history shows which elements were developed over the years and which were abandoned. You can see changes to the menu, the way services are presented, CTAs, categories, filters and the whole information architecture. The point isn't to copy a competitor's solutions. Watching the direction of change is far more interesting. If a company consistently strengthens a particular category over three successive redesigns, or moves important elements higher and higher in the hierarchy, you learn about its business and content priorities. ## How to check a domain's history before buying it: checklist An attractive domain name alone isn't enough to make a buying decision. Before you take it over, check its earlier use and its SEO signals. 1. **Check the Wayback Machine.** Establish which sites previously ran under the domain and whether their subject matter was consistent with the intended use. Compare the oldest and newest snapshots to see how many times the nature of the business changed. Pay attention to periods when the domain was used for spam, doorway pages, gambling, mass affiliate content or content unrelated to its original subject. 2. **Check the current registration data** in RDAP or on the relevant registry's site. For .pl domains, that is NASK (dns.pl). 3. **Check the link profile.** Identify referring domains, anchors, lost links and links pointing to pages that no longer exist. 4. **Check historical visibility.** Sudden, long-lasting drops may point to a moment that needs further analysis. 5. **Find the most valuable old URLs.** If the domain has strong backlinks pointing to deleted addresses, plan how to use them before launching the new site. 6. **Don't judge a domain on a single indicator.** Domain age, number of links or a single tool metric don't describe its whole history. ## Why isn't a site in the archive? A site's absence from the Wayback Machine doesn't mean it never existed. The archive's robot may not have discovered it. The site may have been password-protected, inaccessible to the crawler or built in a way that makes capturing difficult. Problems also affect elements generated by JavaScript and pages that ordinary links didn't lead to. The Internet Archive also notes that site owners can submit requests to exclude material from the Wayback Machine. For this reason, treat a missing snapshot as **a lack of data in this particular archive**, not as proof that there was no earlier history. ## Wayback Machine limitations: why it isn't a backup of your site You can recover a surprising amount of material from the Wayback Machine, but the tool is no substitute for regular backups. The archive doesn't give you access to the database, CMS panel, server configuration, user accounts or the full application environment. Nor does it guarantee that all graphics, CSS, fonts, scripts or other resources were saved. The Internet Archive stresses that simple HTML sites are archived more easily than sites that rely heavily on JavaScript and dynamically loaded resources. The organisation also states explicitly that it does not guarantee that a given site will be archived and does not provide a public service for restoring full copies of lost sites. That's why a backup and an internet archive serve two different functions. A backup is for restoring your site. The Wayback Machine is mainly for recovering information about how the public part of a site looked in the past. ## Alternative tools for checking site history The Wayback Machine remains the most universal starting point, but other tools solve other problems. | Tool | What you can check or do | When it's especially useful | Key limitation | | --- | --- | --- | --- | | Archive.today / Archive.ph | You can save a text and graphic copy of a chosen page | Preserving a specific state of a page, announcement or price list | Doesn't replace a crawl of the whole site; saved pages don't keep active scripts | | [PageFreezer](https://www.pagefreezer.com/website-archiving/) | You can automatically archive pages, including dynamic content | Compliance, legal documentation, company archiving | It's a business solution, not a simple free alternative to the Wayback Machine | | [Stillio](https://www.stillio.com/) | You can automatically take screenshots of pages at set intervals | Monitoring competitors, prices, offers and visual changes | Focuses on recurring screenshots, not on reconstructing a whole historical site | | Archivarix | You can rebuild a site from Wayback Machine data | Recovering an old site that you have rights to | Reconstruction quality depends on which resources were saved earlier | | RDAP / registry search | You can check a domain's current registration data | Verifying a domain before buying | Shows current registration data, not the full history of owners | | Ahrefs | You can analyse backlinks, lost pages and historical SEO data | Link profile audit and migration analysis | Doesn't show a visual copy of the old site | | Semrush | You can analyse changes in visibility and keywords | Finding moments of organic growth and drops | Doesn't replace a site archive | ## A practical example: how a site's history helps find errors after a migration After an online shop migration, organic traffic starts to fall. The current crawl shows no serious problems, and the most important pages work correctly. The cause may be URLs that disappeared during the migration but previously generated traffic or had valuable external links. Here's how to find them: 1. **Reconstruct the old structure in the Wayback Machine.** In the Site Map and URLs tabs, look at old categories, offer pages, blog posts and other addresses that are no longer on the site. 2. **Match the list with SEO data.** Compare old URLs with data from Google Search Console, backlink analysis tools and earlier sitemaps. This will show you which of them actually mattered for visibility. 3. **Check what they return today.** Pick out the addresses that give a 404 error after the migration or redirect to a random page. 4. **Set up 301 redirects.** For every valuable address, find the most relevant equivalent in the new structure. 5. **Recreate missing content.** If there is no equivalent, check whether it's worth restoring the content or preparing a new page that answers the same search intent. This way you'll find problems that a crawl of the new version of the site alone won't show. ## FAQ: common questions about website history **Is the Wayback Machine free?** Yes. Basic searching and browsing of publicly available Wayback Machine snapshots is free. You can also use Save Page Now to capture a specific URL at no cost. **Can you still check a site in Google Cache?** Not in the old sense of the feature. Google removed its own links to cached copies, and the cache: search operator stopped working. Google also officially withdrew the documentation for this operator, because the feature is no longer supported. Since 2024, however, Google has started offering links to the Wayback Machine for available pages in the “About this result” panel. This is not a return of Google Cache, though, because the user is taken to the Internet Archive. **Can you recover a whole site from the archive?** Only to the extent that the archive saved its resources, and without the database or CMS panel. You can rebuild your own site by hand from snapshots or with a tool such as Archivarix, but the quality always depends on what made it into the archive earlier. **Why does an archived page display without images?** Most often because the image file wasn't saved along with the page, was loaded from an external host, or the archive doesn't have the right version of the resource. A similar problem affects CSS, fonts and JavaScript. **How do I remove my site from the Wayback Machine?** The Internet Archive accepts requests to exclude sites from the archive. Its documentation says an owner can send the organisation a removal request giving the site's address. The request alone doesn't mean every item is automatically deleted, because the Internet Archive reviews such submissions. **How far back does the Wayback Machine go?** The Internet Archive has been archiving sites since 1996, and they have been publicly browsable through the Wayback Machine since 2001. The oldest captures mainly concern popular sites, though, so smaller sites often have their first snapshots much later. **Can I check an old version of a robots.txt file in the Wayback Machine?** Yes, if the archive saved it. Enter yourdomain.com/robots.txt and pick a date. This is useful for traffic drops, because it lets you check whether important sections of the site were blocked for bots in a given period. ## Site history is a diagnostic tool, not an internet curiosity Browsing pages from years ago can be interesting in its own right, but in SEO what counts is what you take from these records. Don't treat a single snapshot as a complete copy of a site, and don't judge a domain's history on the basis of one tool. Compare sources, dates, URLs and SEO data, and the internet archive will start to really help you with decisions about your site. Planning a migration or looking for the cause of a traffic drop?
