Ranking test: can there be too many links to your home page?

In an online webmaster forum, a webmaster described the link experiment that he did with his websites. He tried to find out how linking to the home page affected his rankings.

What did the webmaster test?

The webmaster tested the effect of links from sub pages of his website to his home page. He tried links to the home page of his website from the navigation and from the content and he tried links with and without keywords.

The test was done with a 4 year old domain name with a dedicated IP address. The web pages were HTML only. The website ranks top 5 in Google for its main, second and third keyword phrases and it has a total of 90 pages with unique content.

What were the results of the test?

It seems that too many links to the home page of your website can have a negative effect on your rankings:

1. Linking to the home page from every page in the content with the same keyword caused a six pages drop in rankings (-6 pages).
2. Linking to the home page from every page in the content using keyword variations caused a three pages drop in rankings (-3 pages).
3. Linking to the home page from the navigation with “main keyword” also caused a six pages drop in rankings (-6 pages).
4. Linking to the home page from the first 10 pages listed on Google.com for “site:domain.com/*” increased the ranking from 5th to 3rd (+2 positions).

The webmaster also observed the following:

• Linking from the content using keyword variations was effective to a point, after which the rankings dropped.
• There seems to be a page threshold. If the number of pages that link is even slightly above the threshold, the rankings will drop.

Does this mean that you shouldn’t link to your home page?

It’s hard to tell whether the results of this experiment are valid because there are too many other variables that influence the rankings of a web page.

It doesn’t sound sensible that Google will downrank a web page that has a link to its home page on every page. Most users expect a link to the home page on every page of a website and even Google has a link to its home page from every page.

As Google’s usual webmaster advice is to focus on the website user, it seems implausible that Google would penalize home page links.

We think that it’s more likely that the ranking drops are caused by Google’s change filter. If you change your web page contents, Google will temporarily downrank your web pages. This has been described in a Google patent.

Do search engines think that your website is spam?

About three weeks ago, Microsoft was granted a new patent with the name Web Spam Classification Using Query Dependent Data. Although this patent application was filed by Microsoft, all major search engines probably use similar methods to classify web pages.

How do search engines analyze web pages?

Search engines look at a number of elements that can appear on web pages and within queries that web surfers use to find these pages.

For example, search engines may look for the most frequent keyword in the web page, the number of times a particular keyword appears in the web page, the domain name associated with the web page, the number of links pointing to the page, the HTML tags in which a keyword appears and many other factors.

The patent filing indicates that search engines look at hundreds of different factors to rank web pages.

How search engines try to detect spammy pages

The are so many potential spam pages on the Internet that search engines cannot identify all spam pages manually.

To identify potential spam pages, search engines might manually label some web pages as spam and then take information from that pages to find other spam pages.

For example, a web page that uses keyword stuffing has more keywords than a legitimate page. By training the spam detection algorithm with a few web pages that use keyword stuffing, other web pages that use keyword stuffing can be detected automatically.

In other words, a spam detection algorithm labels web pages as spam or not spam by looking at decisions made by humans. According to the patent application, the algorithm might look at the following factors:

• the number of inbound links coming from labeled spam pages
• the top level domain of the site
• the quality of phrases in the document and density of keywords (spammy terms)
• the count of the most frequent term
• the count of the number of unique terms
• the total number of terms and the number of words in the path
• the number of words in the title
• the rank of the domain and the average number of words
• the top-level domain
• the number of hits within a domain
• the number of users of a domain
• the number of hits on a URL and the number of users of a URL
• the date the URL was crawled, the last date page changed
• many more factors

If your website uses similar elements as the spammy web page then it’s likely that your website will be classified as spam. The usual impact of a website being labeled as spam is that the site might be pushed down in search results, or removed completely.

What does this mean for your website?

You should make sure that your web pages use similar elements as the top ranked pages instead of elements that can be found on spam pages.

How To Select The Right Keywords For SEO

Keywords selection is a very important process before you start applying SEO to your website. This is because without proper keyword planning, your SEO effort will not bring you any conversion as visitors to your site are not targeted at all. Relevancy is the key here.

When you are doing your keyword research, it is important for you to choose the most relevant keywords for your business. Basically, keywords can be categorized into 3 types, which are: Too Hot Keywords, Just Right Keywords, and Too Cold Keywords. “Too Hot Keywords” are words like “florists”, “translation”, or “gifts”. These types of keywords are too generic, which do not seem to be targeted enough to get conversions. These keywords usually bring in high search volume (which is naturally tempting to optimize) but the conversion may not be as ideal as targeting keywords which falls into the “Just Right” category.  By optimizing those “Just Right” keywords, you can get more targeted traffic to your website and increase the chance of conversions.

For SEO, it does make more sense to target keywords that fall in the Just Right category. As for “Too Cold Keywords”, they are usually long-tail key phrases like “corporate gifts for any event and budget”. When SEO is done correctly, you will get traffic from the long tail phrases due to the overall targeted keyword theme. So what do I mean by targeted keyword theme?

In order to achieve a targeted keyword theme, it really depends on the content that you put on your website. Unique, informative and keyword targeted content is something that you need in order to succeed in SEO. This is because long tail keywords usually take up 60% – 70% of overall organic traffic of a website and it is something every optimizer must capitalize on. So when your website overall content revolves around a particular theme (for example: if you run a SEO consultancy firm, you should come up with articles that talk about SEO methodology, keyword selection and anything that you can think of with regards to SEO.) Although the traffic from long tail are spilled-overs from page 3, 4 or 5 of the SERPs, these traffic are very targeted and may result in conversions.

The bad new is that an optimizer will not be able to predict what kinds of long tail keywords that searchers will use. Therefore, long tail SEO can only be done by targeting the right keyword theme and creating relevant content.

When coming up with long tail content, just treat yourself as an educator. Write informative articles to educate your target market about the product or service that you are providing. In this case, you will be able to move your prospects that are in the research phase to the buying phase, which increases your chance of conversions.
