Researching link-building opportunities – free alternatives to Ahrefs or SEMrush

To do link building, you first need to identify the right placements for your links: websites that have high authority and relevant content. You can find the right placements by either looking at competitors’ links, finding broken links, or reverse image search. Yes, Ahrefs or SEMrush can help you do all that without the knowledge of advanced search operators, but this comes at a price – from $99 (for Ahrefs) to $129 (for SEMrush) for the lowest-tier starting plan, to be precise! 

The good news is – there are plenty of free tools for competitor backlink checking, and you can easily find relevant websites in Google with search operators and reverse-image search for free!

Free competitor backlinks checkers

Looking at your competitors’ backlink profiles can provide valuable insights for your own SEO and digital marketing strategies. Here are some key reasons why analyzing your competitors’ backlink profiles and keyword research is beneficial:

  1. Identify Link Building Opportunities: By examining where your competitors are getting their backlinks from, you can identify potential websites or platforms that might also be willing to link to your content.
  2. Understand Link Quality: Not all backlinks are created equal. By analyzing the quality of your competitors’ backlinks, you can prioritize obtaining links from high-authority websites and avoid low-quality or spammy ones.
  3. Discover Content Ideas: The content that earns backlinks for your competitors can inspire your own content creation. If a particular topic or format is attracting a lot of backlinks for them, it might be worth exploring for your own site.
  4. Uncover Partnership or Collaboration Opportunities: Some backlinks might come from partnerships, guest posts, or collaborations. Identifying these can give you ideas for potential partnerships or collaborations of your own.
  5. Benchmarking: By comparing your backlink profile with that of your competitors, you can gauge where you stand in terms of link quantity and quality. This can help set realistic goals and KPIs for your link-building efforts.
  6. Identify Negative SEO Attacks: If you notice a sudden surge of low-quality or spammy backlinks pointing to a competitor’s site, it might be an indication of a negative SEO attack. Being aware of such tactics can help you take preventive measures for your own site.
  7. Understand Industry Trends: The type of content and sources that are linking to competitors can provide insights into industry trends and shifts, helping you stay ahead of the curve.
  8. Refine Your SEO Strategy: By understanding the backlink strategies that are working for competitors, you can refine your own approach, focusing on tactics that yield results and discarding those that don’t.
  9. Avoid Google Penalties: By studying competitors’ backlink profiles, you can identify tactics that might lead to Google penalties. This can help you avoid similar pitfalls.
  10. Measure the Effectiveness of PR Efforts: If your competitors are getting backlinks from high-profile publications or industry influencers, it can give you a sense of the effectiveness of their PR or outreach campaigns.

In essence, analyzing competitors’ backlink profiles is a proactive approach to enhancing your own SEO strategy, allowing you to learn from both their successes and mistakes.

Now let’s look at tools that will allow you to perform competitors’ link analysis for free!

Free broken links checking tools

Why should you care about broken links?

Broken link building is a tactic where you find broken links on other websites, especially those relevant to your niche, and then suggest your own relevant content as a replacement. Here’s how it can be a good link-building strategy:

  1. Identify Broken Links: typically using tools like Ahrefs, SEMrush, or Screaming Frog to find broken outbound links on websites relevant to your niche – I will show you the free broken links building tools in a second below!
  2. Analyze the Content: Check what the broken link originally pointed to. You can use the Wayback Machine to see the content of the now-defunct page.
  3. Create/Match Content: If you already have content that matches the topic of the broken link, great! If not, consider creating high-quality content that can serve as a replacement.
  4. Reach Out: Contact the website owner or webmaster, informing them about the broken link and suggesting your content as a replacement. Ensure your outreach is polite, helpful, and provides value.
  5. Build Relationships: This tactic is not just about gaining a backlink but also about building relationships with other website owners or bloggers in your industry. A positive interaction can lead to more collaboration in the future.
  6. Beneficial for Both Parties: The website owner gets to fix a broken link, improving their site’s user experience and SEO, while you gain a valuable backlink.
  7. High Success Rate: Compared to other outreach methods, broken link building often has a higher success rate because you’re providing a solution to an existing problem.

In conclusion, while broken links can be detrimental to a website, they also present an many link opportunities and opportunity. By adopting a proactive approach and leveraging the broken link building tactic, you can turn potential pitfalls into valuable link-building opportunities.

Now, let’s see which free tools you can use for it!

Ahrefs broken links checker 

Ahref's broken links checker

Again, if you’re looking for free broken link checking tools – Ahrefs comes to the rescue with their free version of their tool.

ahrefs broken links check

dead link checker broken links

Dead link checker allows you to search up to 2000 broken links – unfortunately, it offers only outbound broken links (= the broken links on your own site) – so it’s useful more for technical audits and improving your site’s quality.

Google Search Console – for your own broken links

google search console to review linking domains

Google Search Console (GSC) is a valuable tool for website owners and SEO professionals. One of its uses is to help uncover broken links on your website. Here’s how you can use Search Console to find and fix broken links:

  1. Log in to Google Search Console:
  2. Coverage Report:
    • In the left sidebar, click on “Coverage.”
    • This report will show you errors, valid pages with warnings, valid pages, and excluded pages.
    • Look for errors related to “404 Not Found” or “Soft 404.” These indicate broken links or pages that Google tried to crawl but couldn’t find.
  3. Details of Errors:
    • Click on the specific error type to get a detailed list of URLs that are affected.
    • You can then investigate each URL to determine the cause of the error and fix it.
  4. Internal Links Report:
    • In the left sidebar, click on “Links” and then “Internal Links.”
    • This report shows pages on your site that receive the most internal links. If any of these pages are broken or have been removed, it’s crucial to address them since they might be important for your site’s navigation and user experience.
  5. Inspect URL:
    • If you suspect a specific URL might be broken or if you want to check the status of a fixed link, use the “URL Inspection” tool at the top of the Search Console dashboard.
    • Enter the URL, and GSC will provide information about the last crawl, any detected issues, and the canonical URL for that page.
  6. Addressing the Broken Links:
    • Once you’ve identified broken links, take action to fix them. This might involve:
      • Redirecting the broken URL to a relevant live page using a 301 redirect.
      • Updating the link to point to the correct URL if it’s an internal linking issue.
      • Removing the link altogether if it’s no longer relevant.
      • Restoring a mistakenly deleted page.
  7. Mark as Fixed:
    • After addressing the issue, you can mark it as fixed in the Search Console. Google will then re-crawl the page to verify the fix.
  8. Monitor Regularly:
    • Regularly check the Coverage report in GSC to ensure new broken links don’t emerge. Websites are dynamic, and issues can arise from updates, changes, or even external factors.
  9. Additional Tools:
    • While Google Search Console is a great starting point, consider using additional tools like Screaming Frog, Ahrefs, or SEMrush for a more comprehensive broken link check, especially for larger websites.

Remember, broken links can harm user experience and potentially impact SEO. Regularly monitoring and addressing these issues ensures a smoother experience for your visitors and can help maintain your site’s search performance.

Reverse image search

Google reverse image search - example

Performing a reverse image search in Google allows you to find where else an image appears on the web, discover visually similar images, or track down the original source of an image.

Here’s how you can do it:

Go to Google Images: Open your web browser and navigate to Google Images.

  • Click on the camera icon in the search bar, which says “Search by image.”
  • You’ll see two options: “Paste image URL” and “Upload an image.”
  • Paste image URL: If you have the URL of the image, you can paste it here.
  • Upload an image: Click on “Choose File” to select an image from your computer to upload.
  • Review the Results: After uploading the image or pasting the URL, Google will display the search results, which might include:
    • Web pages that include the image.
    • Visually similar images.
    • Different sizes and resolutions of the same image.
