Backlink Checkers: Free and Paid Software and Services
|Note: Google has recently abolished Page Rank, that is why some information in this post may be out-of-date. Instead, we use own evaluation system – SB Rank, which is based on DA and PA index.|
About 5 years ago, any backlinks can be viewed via search engines. At that time, using special requests, like “link: site.com”, you could find out who links to a given resource. The information was incomplete, but sufficiently detailed.
In order to complicate optimizers’ life and reduce the possibility of artificial influence on search engines, these operators have been canceled (Google still has such opportunity, but its backlinks information is so meager that it has not been worth mentioning).
But if you cannot stop an outrage, you must lead it. As soon as “link:” were canceled, a large demand for information on external links resulted in extension of special services that provide this information. These services operate on the principle of search engines – internet indexing. But, unlike SE, they do not analyze sites and only collect specific information about reference sources.
Backlinks are one of the fundamental aspects in site promotion. They are important to know, and not only for your domain. It is necessary to know how to check competitors’ backlinks for assessing the promotion budget and for identifying new ways of linkbuilding. There are a variety of services (both paid and free) to find backlinks to a website. Each has a database of all relevant sites and pages on the network, or at least parses those who have this base. It is necessary to understand that since all these services have different sampling, as well as database relevance, the backlinks data will be different and will never be the same as from the search engines. However, this error is not significant and can be neglected.
Backlink check gives you the next opportunities:
- To know which links actually work and which can be removed lossless.
- To compile a complete anchor list, and always be up to date in how many and what anchor text is used (in total and separately).
- To track changes in the quality of links (closing the indexing, adding other inbound links to the same page, etc.).
- To minimize the cost of link building by dropping out of “bad” donors.
- To optimize and arrange the backlinks base, and to see not the separate fragments, but the whole picture.
- To monitor the dynamics of site positions growth, based not on conjecture, but on concrete facts.
- To reduce time loss for manual checking.
But as well as you should check backlinks carefully, you shouldn’t overdo. Find balance to prevent analysis paralysis. If you care only about how to check number of backlinks to a website, your competitors will outperform you. Beware of it.
Best online backlink checkers software for SEO
Up to this date, it’s probably the best checker with a very powerful functionality. Some features may be used free of charge (after registration), but still service is paid. The cheapest plan can be taken for 79$.
Ahrefs.com is a tool for analyzing incoming backlinks, with which you can analyze the competitors’ referential mass, and on the basis of the obtained data develop or improve your backlink building strategy. Let’s consider Professional mode in our review.
- To start the analysis, pass to “Backlinks,” insert the domain address and click “Search Links”.

Also, Ahrefs displays important information about link parameters, such as “nofollow”/”dofollow” ratio, text and redirect anchors ratio, image links, etc. A lot of useful information is displayed in graph form (i.e., linking domains or phrase anchors).
- Passing from the main overview tab on the other, it is possible to consider a more detailed picture of the analysis. For example, “external” tab displays a list of all found links that can be filtered by various parameters. “New/Missing” tab displays a calendar grid and a graph with the image of new and missing links. Get a list of referring domains by clicking on the correspondent tab (what is more, near to each address you can see its main characteristics). “Top Pages” displays all pages that have been indexed by the service robot. “Anchor” tab allows the review of link anchor texts.
- Using filters, you can sort the anchors on various parameters, for example, display only the nofollow links or redirects.
- “Export data” displays all available data information and allows exporting it in csv format.
- “Search references” allows monitoring the activity of a brand or a particular term/keyword. Passing to “other instruments”, you get access to some features that will undoubtedly be useful in the analysis: backlinks report, comparison of domains and batch analysis. In competitors’ analysis, “Comparison of domains” is particularly useful tool, as with it you can get comparative information across multiple sites, up to 5 at the same time.

Social Media Links
New social links positively affect topics, related to the daily life of the people, entertainment and other social issues. Each resource requires a separate analysis and individual promotion strategy. Anyone who uses additional links for the promotion of social sites must keep in mind the following things:
- Use the links, tweets and likes only as an auxiliary method of promotion. Using social links separately from SEO-references is impractical and will not bring a stable effect.
- Social networks signals work, but only for a limited number of themes.
- Twitter links provide temporary effect.
- Website with bad behavioral factors will not get positive effect from social links.
- The resource must have group in social network, or either the effect of social links will be very weak for any sites.
DOFOLLOW Link Checker Tool
Dofollow edu links, as well as .gov links, add credibility in the eyes of search engines, as they belong to educational and government institutions. To get backlink from such resource is a great honor.
PageRank was introduced to resolve the issue of the page “importance”. PR is a numeric value, which is a measure of web page “importance”. Google experts believe that when one page has a link to another, the first gives weight to the second. In addition, the rate of the “importance” of voting page determines the “importance” of the vote.
Some links may negatively affect the site rank. Google understands that webmasters are not able to influence the external links to the site, but they can completely control outbound links. Therefore, references to the website can not hurt it to the same extent as outbound ones. So, you should be careful about sites on which you make reference. PR0 is usually a penalized site.
Simplifying PP formula, we get PR= 0.15 + 0.85* (PR “relative value” of each page that links to your target page). This unique formula is derived in the development of the “PageRank” concept, and probably Google uses a modified version of it. But it does not really matter, as the equation presented above is quite accurate. “Relative value” is the ratio of PR to the page number of outbound links. The total PR value that page can use to vote is little less than the actual PR value (actual value * 0.85). It is distributed equally between all the pages that are referenced by voicing page.
Therefore, we can conclude that the PR4 link with 5 outgoing links give more weight than PR8 link with 100 outgoing links. The more links on the page, the less PR your page will receive as a result. There are a lot of domain google pagerank (PR) checkers – small SEO tools that help you to find out Google PR in a few seconds.
How to check all your site back links anchor text for spam?
Anchors significantly influence the position of the site, so they are considered for promotion. Properly written anchor plays an important role in the reference ranking.
How to make the anchor correctly?
- Anchors quantity. Anchors with the same text can’t bring profit. The ratio of diluted anchors to undiluted ones must be within 70-75% to 25-30%.
- Construct anchor using clear grammatical rules.
- Compliance with the site theme. Link should be placed on the site dedicated to thematic topic.
- Presence of grammatical or punctuation errors is another reason to refuse to post links.
- Keywords uniqueness. Dilute anchors with various adjectives.
There are several services to check backlink anchor text, i.e., Backlink Watch, Smart backlinks tool, Analyze Backlinks, Link Diagnosis, etc.
How to build quality backlinks?
Stereotype that the more links the better is still presented in the minds of website owners. Another problem is the haste and carelessness when buying links. So, what is needed to be considered when analyzing the anchor list:
- Branded anchors. This can be a company, brand or site name, and other signs of belonging to the company.
- None-anchor anchors. Links are frequently made on the words “here”, “online”, etc. If the percentage is small, it should be increased.
- Image links. These can be banners that are a good tool to dilute the anchor list and give a natural reference weight. SE use attribute “Alt” as an anchor text.
- The percentage of search queries and their variations.
- Absence of spam. Spammed anchor list contains an excessive number of promoted phrases in the anchor text.
- Grammatical correctness. The use of unnatural morphological structures is unacceptable.
General recommendations for exemplary percentage of links in the anchor sheet:
- Direct entry of the key requests – up to 10%.
- Branded keywords – about 10%.
- Synonyms, alternative words, query link texts diluted with additional words – 40-50%.
- None-anchor links: for new sites – up to 50%, for old – up to 30%.
Uniform link distribution
You should pay attention on the uniformity of bought links. Predominance of references to the main page of the site signs to search engines that link building is unnatural. Do not focus all reference weight only on the promoted pages. Checking the quality of donors is important as well. It should be performed when selecting donors, and must be periodically rechecked.
To protect your site against sanctions of search engines you should carry out a competent external SEO. Do bet on qualitative links.
