lOOkkle Free Backlink Checker

A Backlink Checker is an essential tool for any SEO strategy. It allows you to analyze the links pointing to your website, which is crucial for evaluating the quality of your backlink profile.

A healthy and high-quality backlink profile is key to maintaining or improving your rankings on search engines like Google.

Our free backlink checker allows you to get a clear overview of all the backlinks that influence a website's SEO, i.e. the most important backlinks for that site, but with limited and complete daily use.

• DoFollow backlinks pass SEO value and authority from the source site to your site.
• NoFollow backlinks do not transfer SEO authority but can still bring traffic and brand visibility.

• Link Rank measures the strength of an individual backlink (0-100).
• Domain Rank measures the authority of the entire referring domain (0-100).

Link building is an SEO (web positioning) strategy that involves obtaining links from other websites to yours.
These links are called backlinks and function as "votes of confidence":
• If a relevant and trustworthy website links to your page, search engines (like Google) interpret your content as useful and valuable.
• The more quality links your site has, the more authority it will gain and the more likely you are to appear in the top search results.

• Quality over quantity: It's better to have a few links from relevant websites than many links from untrustworthy sites.
• Naturalness: Google or Bing penalizes artificial practices (mass link buying, link farms, spam).
• Diversity: Obtain links from different types of pages and formats (blogs, news outlets, directories, social networks, etc.).
• Valuable content: The best link magnet is to publish useful, original, and shareable content.

• Get mentions on blogs or in the media.
• Guest post (write articles as a guest on another site).
• Create infographics, studies, or guides that others want to link to.
• Participate in forums, directories, or specialized communities (without spamming).

• A quality backlink tells Google that your content is valuable.
• The more relevant links you have (from trusted, authoritative sites), the greater the likelihood of ranking high.
• More important are links from quality sites on the same topic as the targeted site.
• An important site for Google is a site that appears at the top of its search engine.

• Bing gives more weight to on-page factors (optimized content, tags, site structure) than Google.
• Bing even highly values links from official, educational, or trusted sites (.edu, .gov, large media).

• These AIs don't use backlinks as a ranking signal because they aren't traditional search engines.
• If your website gains authority and visibility thanks to backlinks, it will appear better on Google/Bing.
• By ranking higher, your content is more likely to be crawled, indexed, and referenced in AI datasets or real-time searches.

• See where they get their links from.
• Detect patterns (blogs, media, forums, directories, collaborations).
• Get inspired to replicate or surpass their strategy.

• Review what links you currently have.
• Identify if there are toxic links that could affect your SEO.
• Measure quality (domain authority, topical relevance).

• Find sites that already link to your competitors but not to you.
• Look for broken links (broken link building) that you could replace with your content.
• Detect mentions of your brand without a link and request that it be added.

• URL FROM & URL TO: Gain insights into the origin and destination of your links, helping you better understand your backlink network.
• Anchor: Review the anchor text used in backlinks, ensuring proper keyword optimization.
• Title: Its main function is to display a tooltip when the user hovers over the link.
• ALT: It's used in image links to describe the content of an image. It helps search engines understand the image's content.
• Rel: Dofollow or Nofollow: Identify whether your backlinks are dofollow (passing SEO authority) or nofollow (not passing SEO authority), which directly impacts your SEO performance.
• Image: Someone posts an image on their website and that image includes a link to your page.
• Lost Link: This is a backlink that previously existed pointing to your website, but is no longer available.
• Link Rank: This is a metric that attempts to measure the strength or authority of an individual link based on various SEO factors. Its scale ranges from 0 to 100, where 100 represents the strongest and most valuable link.
• Domain Rank: Evaluate the authority of the domain linking to your site. Higher Domain Rank means greater SEO impact from that backlink.
• First Seen: This is the first time the tool detected the existence of the backlink on the source website.
  It indicates the age of the link, which helps determine whether a backlink is new or has been providing authority for years.
• Last Visited: This is the last time the tool crawled and confirmed that the backlink still exists on the source page.
  It is updated each time the crawler revisits the link.
• Review Date: Keep track of your backlinks with review dates to ensure your link profile stays up-to-date.

• First Seen: the date when Lookkle first detected the backlink.
• Last Visited the most recent date Lookkle confirmed the backlink is still active.

• Follow vs NoFollow: helps you understand how many backlinks pass SEO authority.
• Domain Rank distribution: shows how strong or weak your referring domains are, based on their authority.

Evaluate the quality of a website's backlinks and improve its SEO strategy

Use Case:

This helps me identify high-quality backlinks that increase my domain authority, and remove or improve low-quality ones that could be negatively affecting my Google rankings.

The top arrow located to the right of "Domain Rank" allows you to sort from best to lowest ranking of the URL that links to you.

Using Lookkle's Backlink Checker tool, I can filter links by traffic and domain, ensuring that most of my backlinks are coming from sites that are local or related to my business's industry. This helps improve my local SEO and increase visibility in geo-targeted searches.

Ensuring that products have enough quality backlinks

Use Case:
As a marketer for an e-commerce site, I want to make sure that my product pages are being supported by high-quality backlinks.
By analyzing with Lookkle's Backlink Checker, I can see which links are pointing to each product page, checking metrics like Domain Rank and monthly traffic from the linking domains. If I find that product pages don't have enough relevant links, I can start a link building campaign focused on those products.

For example, I can enter the name of the website I'm interested in analyzing on my website and sort by monthly traffic to see which websites are sending me traffic.
If the website I'm interested in analyzing on my website is "website-traffic", I enter this part of the URL into the search engine and sort by web traffic.
