In this digital era, people use search engines, such as Google, to determine who they contact, where they shop and how much money they spend on anything they need to purchase. Consequently, many businesses have made their transition to the internet.
Odds are, you may not realize what either is or how they work. Take a look to better understand both and how they affect your SEO. Then, you can decide which one works best for your needs.
- How a site using JS can be crawled, indexed and then ranked
In the past, JS was only ideal for front-end (client-side) browser. These days, the code can be embedded on other host software like server-side in website servers as well as databases.
To understand why problems occur and how you can prevent them, you need to have some basic skills on how search engines work. Let’s have a look at the information retrieval phases: crawling, indexing, and ranking.
Crawling, indexing and ranking
Crawling is the discovery phase. It is a rather complicated process that uses software programs known as spiders or web crawlers. A popular example of a web crawler is Google bot.
Here is what the process looks like:
A crawler fetches web pages. It then follows the links on these pages and the process continues until the pages are indexed. During indexing, the crawler uses a parsing module that analyzes code and extracts URLs in the <ahref=”…”> script without rendering them. Web crawlers can validate HTML codes and hyperlinks.
You can use a "robots.txt" file to assist Google in finding the pages to crawl. This file communicates to search engines on whether they should access and crawl your entire site or just some parts of it.
The crawling and indexing phase work together. The crawler sends its findings to the indexer which in turn prioritizes the URLs according to their high value and feeds more URLs to the crawler.
Once this stage is complete, and there are no errors in the search console, the ranking process begins. At this point, Onsite SEO experts and webmasters must offer quality content, optimize the website and build valuable links.
Of course, search engines have numerous measurements when it comes to a site or page's ultimate ranking. For more insight into how Google ranks content, Backlinko has created a list of 200 ranking factors, which was current as of late 2018. This will help you further create the right content to rank higher.
One of the best ways to do this is to use the Fetch as Google tool. You can also a variety of tools and frameworks, such as:
- Angular JS SEO
- Backbone JS SEO
Iframes (inline frames) are part of the HTML syntax. They allow you to embed another site on your website's code. As such, it enables you to use resources from other sites without duplicating content.
For instance, you can use iframes to embed maps from Google, slideshows from SlideShare, engaging AI Chatbots, and videos from YouTube as well as content for advertisement.
Initially, the challenge with iframes was that search engines were unable to crawl iframe content. Users could see the content but robots couldn't. Also, robots were unable to leave the iframes once they entered. This meant they were stuck and weren't able to see any other content on your site.
Iframes and cloaking
A common myth about iframes is they are used as a form of cloaking. This risky technique is used to obscure poor quality content by showing search engines a completely different set of content than what users actually see. As you might have guessed, this approach can have negative impacts on your search engine ranking as it defeats the purpose of ranking.
Mainly, users quickly leave your site when the content isn't what they expect. Even if you do fool search engines temporarily, they figure out there's an issue when you have an extremely high bounce rate.
Search engines have changed drastically in the last decade to cut down on blackhat SEO practices. Think of cloaking as being just as bad as buying backlinks and keyword stuffing. All of these will drop your site in search rankings and possibly even get it blacklisted, which is difficult to come back from.
Iframes are distinct from cloaking. They mark the source of their content in the HTML syntax. Search engines, therefore, understand that the content seen by users is similar to the content referred to in the source URL. This is a legitimate method for providing quality content to users.
Iframes and search engine rankings
Can Iframes affect your site ranking? Search engines consider the content in frames to belong to another website. This means having them doesn't really affect your search engine ranking, for better or worse. However, you can assign iframe content a different URL to make it appear to search engines as a link on your site versus a completely different website.
There is one way where iframes may hurt your site rank. Since search engines see them as a separate URL, placing your best content and resources in them may result in the iframe content being seen as a competitor.
Overall, it's better to focus on placing high-quality content on your website and not just in iframes. While you can still use iframes, use them for less important content. Remember, you want your main site to rank high and not let your iframes take away your ranking power.
Some site owners use iframes for additional or secondary content. This gives users extra content, but ensures search engines see the highest quality content as coming from the parent site and not a competitor.
