Important metrics to monitor<\/h3><p>To evaluate the quality of a backlink, you cannot rely solely on quantity. You need to analyze the following metrics:<\/p><ul>\n<li><strong>Domain Rating (DR)<\/strong>: Indicates the overall authority of the website, provided by Ahrefs. DR of 50 or higher is considered good quality.<\/li>\n<li><strong>URL Rating (UR)<\/strong>: Assesses the strength of the specific URL containing the backlink. High UR along with relevant content is a good sign.<\/li>\n<li><strong>Spam Score<\/strong>: Moz's metric (0-17) helps detect spam risk. &gt;7 is often a warning sign.<\/li>\n<li><strong>Dofollow\/Nofollow<\/strong>: \u201cdofollow\u201d backlinks provide real SEO value, but should only account for about 60-70% to diversify the link profile.<\/li>\n<\/ul><div class=\"wp-block-group has-background\">\n<p><strong>\ud83d\udca1 TIP:<\/strong> A reputable website with high DR but with links placed in the footer or site-wide can still be considered unnatural. Prioritize links within the main content.<\/p>\n<\/div><h3>2. Checklist for evaluating backlinks from the start<\/h3><p>Before adding a backlink or when checking old backlinks, you can use the following checklist:<\/p><ul>\n<li>Does the linking website have content on the same topic?<\/li>\n<li>Is the link placed within the article (not in the sidebar\/footer)?<\/li>\n<li>Does the website have a history of spam or Google penalties?<\/li>\n<li>Is the backlink from reputable domains (e.g., .gov, .edu, or mainstream news sites)?<\/li>\n<\/ul><h3>3. Practical examples &amp; report data<\/h3><p>A DPS.MEDIA client (anonymous) once had more than 500 backlinks, but most of them came from blog comments on websites with <strong>Spam Score &gt;10<\/strong>. After removing 65% of bad links, the main keyword ranking increased from #32 to #9 in 3 months (according to Ahrefs, Q2\/2023).<\/p><table class=\"WordPress\">\n<thead>\n<tr>\n<th>metrics<\/th>\n<th>Safe threshold<\/th>\n<th>High risk<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Domain Rating (DR)<\/td>\n<td>> 30<\/td>\n<td>< 15<\/td>\n<\/tr>\n<tr>\n<td>Spam Score<\/td>\n<td>0 \u2013 4<\/td>\n<td>> 7<\/td>\n<\/tr>\n<tr>\n<td>Dofollow Ratio<\/td>\n<td>50 \u2013 70%<\/td>\n<td>&gt; 90% or < 20%<\/td>\n<\/tr>\n<\/tbody>\n<\/table><h3>4. Risks of ignoring backlink analysis<\/h3><p>Not thoroughly checking link quality can lead to Google penalties related to <strong>unnatural links<\/strong>. Penguin algorithm update (Google, 2016) caused thousands of websites to drop in rankings due to backlinks from PBNs or spam forums.<\/p><div class=\"wp-block-group has-background\">\n<p><strong>\u26a0\ufe0f Note:<\/strong> Index evaluation should not be done only once but needs to be checked periodically (every 2-3 months) to promptly handle bad links.<\/p>\n<\/div><h3>Key Takeaway:<\/h3><p>A quality backlink comes not from quantity but from relevance, naturalness, and authority metrics. Systematic analysis will help protect your website ranking from unexpected algorithm changes.<br><img decoding=\"async\" class=\"kimage_class\" src=\"https:\/\/dps.media\/wp-content\/uploads\/2025\/08\/a-gi_1.jpgb3b2.jpg\" alt=\"Strategy to safely remove bad backlinks without affecting SEO\" title=\"\"><\/p><h2 id=\"chien-luoc-loai-bo-backlink-xau-an-toan-ma-khong-anh-huong-den-seo\">Strategy to safely remove bad backlinks without affecting SEO<\/h2><h3>1. Accurately identify bad backlinks<\/h3><p>First, you need to filter and clearly categorize low-quality links. Some common signs:<\/p><p>\u2013 Backlinks from spam websites and irrelevant content<br>\n\u2013 Links from domains with low DA (Domain Authority) or penalized by Google<br>\n\u2013 Backlinks coming from unclear PBN (Private Blog Network) networks<\/p><div class=\"wp-block-group has-background\">\n  <strong>Tip:<\/strong> Use tools like Ahrefs, semrush, or Google Search Console to detect bad links early.\n<\/div><h3>2. Propose a safe removal process<\/h3><p>Instead of mass removal which may trigger abnormal reports, proceed step by step:<\/p><p>\u2013 Contact webmaster and request link removal (response rate ~10-15% \u2013 Ahrefs Report, 2022)<br>\n\u2013 Use Google's Disavow tool to block uncontrollable domains<br>\n\u2013 Track effectiveness by measuring DR (Domain Rating) and organic Traffic metrics<\/p><p>Real-life example: An online retail business lost nearly 40% of its traffic after receiving 500+ backlinks from anonymous forums. After disavowing all, search traffic recovered after 6 weeks.<\/p><h3>3.
