Which is better, to get backlinks from a lot of different domains or from a few domain with a lot of backlinks?

From relevant places with high DA/PA. Building a strong backlink profile requires constatant analysis of acceptor sites (domains that has a backlink to your site).

 Almost all backlinks from a .edu and .gov domain zones are of extremely high quality, but let’s be honest, these are really hard to get. We’ll examine more common links.

 

1. Page Rank and Trust Rank. First off, there’s an easy way to determine the link’s quality on platforms like Serpstat. For each referring page, we display Serpstat Page Rank and Serpstat Trust Rank. The metrics are calculated on a scale from 0 to 100 — the higher, the better. Even a no-follow link from a trustworthy domain will carry more weight than several do-follow links from sites with low SPR or STR. Please note that the trust rank (STR) is more important than SPR because the trust score is calculated based on how authoritative domains/pages link to the researched resource. A tip for you: divide the page’s STR by SPR — the ratio of more than o,5 (0,9-1 desirable) tells you that it’s a quality resource. If the STR is greatly lesser than the SPR, we can say that the site/page has a large amount of low-quality backlinks and getting a link from such resource won’t boost our rankings.
 
2. Link relevance. Next thing to pay attention to is the page topic and the anchor text. If you offer car leasing and want to get a link from a cleaning services site with an anchor like ‘best cars for lease here’, that won’t impact your link juice in a good way. Make sure that the desired link sources address a topic similar to yours. A link from a relevant page may bring more value than a link from a news article on The New York Times.

3. Link from a well-ranking page. Another way to determine how highly a search engine values a given page is to analyze what keywords it ranks for and on what positions. If you are targeting the keyword ‘affordable wedding rings’, it’s worth selecting pages that rank high for that keyword and reaching out to the site owners in an attempt to receive a backlink. Employ our URL Analysis report if you already know what pages you want to get a backlink from, or use Keyword Research > Top Pages tool to learn about the most successful pages for your targeted keyword and reach out to their owners. Earning links from pages that already rank for this keyword would boost your SEO significantly, not to mention the brand awareness thing.

4. Link location. It may come as a surprise, but this matters. For example, sitewide links — those in footers or sidebars, don’t carry much weight. What you need is links inside the content.

5. Links that flow naturally with the content. A good link flows naturally with the surrounding content. If a text passage reads about how to repair your own car without experience and suddenly you input a link with the anchor ‘get an affordable and reliable carburetor here’, it’s perceived spammy by readers and search engines.

6. Nofollow links. Having a certain percentage of nofollow
links is important for a domain’s link profile. Even though they don’t pass valuable link juice, they indicate natural links that reference relevant pages. Don’t neglect to get some amount of nofollow links with relevant anchors 

7. Links from long-reads are more valuable. It is widely known that long-form content performs better in search than short posts. Hence, links from such pages are worth more.

Serpstat Backlink Analysis is a tool used to research the link profile of a website. It will show you the quality of backlinks using metrics like Trust Rank and Page Rank, where they come from and what pages link to, with what anchor text and when they were created.

Step 1. Enter your competitor domain name or URL — depending on whether you want to get the backlinks of the entire site or a specific page and navigate to Backlink Analysis > Backlink Dashboard:
Your primary interest here would be site’s overall backlinks metrics: number of referring domains and pages, the domain’s PR and TR and backlink history. These insights are amazing, but we want to learn more specific data.

Step 2. Open Referring Domains to view all linking domains and the number of backlinks received from them:
The report displays referring domains, their authority metrics and the number of links your competitor received from each of the listed domains. In order to identify what pages from a specific domain are linking to your competitor, simply click the corresponding figure and you’ll get a table like this one:

Step 3. Navigate to the Backlinks tab. The report will display data on all new and lost backlinks of the researched domain for the last 90 days. You can view the SPR and STR for each referring/destination page and identify sources of links that deliver link equity:

The workspace contains a table for new backlinks earned in the last 90 days (click on Show all new backlinks to view the entire report):
And the table for backlinks lost in the last 90 days — find out who has removed a link to your competitor’s site. We can use these insights later as link building opportunities:
Set one link per domain if you want to get one sample link from each referring domain:

Step 5. Open Anchors. The report shows all anchors in the competitor’s backlinks and the number of domains/pages using a specific anchor text. Click on the number of domains/pages next beside the anchor to find out who’s linking to your competitor with a specific anchor text:

Step 6. Browse to Top Pages to learn how many domains/pages are referring to specific pages on your website. The report features all of your pages that we checked for backlinks, the number of linking domains/pages and SPR/STR of each URL:

All of the above reports can be exported by clicking the Export button and choosing the right format. When the file is ready for download, you’ll be able to get it from the Latest Reports.
