What is SEO and what are its benefits for your projects?
SEO (search engine optimization) is the process of optimizing your website in order to get a higher ranking in organic search results and consequently more organic traffic.
SEO is a long term strategy and requires advanced knowledge of ranking algorithms and some technical background, to be able to optimize websites for popular search engines like Google, Bing, Yahoo, DuckDuckGo, etc.
According to the latest survey on digital marketing conducted by TechBehemoths, about 70% of IT companies revealed that SEO is their main channel for leads, meaning that it’s a vital marketing activity that generates traffic, prospects and sales.
Some of the benefits of SEO are:
- Free organic traffic
- Brand awareness
- Better control over brand traffic
- A vital marketing channel for leads & sales
- Supports other channels: social media, paid ads, direct traffic, etc.
- Optimizes your advertising budget
- Usually, has a higher conversion rate
- Gives you a competitive advantage
- Is a good long term investment, generating decent results
It’s not easy to find a reputable SEO company, as some SEO agencies used to provide questionable/suspicious services in the past, and lots of businesses became reluctant to pay for search engine optimization services.
When looking for and choosing an SEO service provider, you should consider a lot of aspects. Ideally, you should do some basic research, set up clear goals and ask yourself a few questions before hiring a company.
Here are some things to look for when searching for SEO agencies to partner with:
- Expertise
- Portfolio
- Years in business
- Case studies
- Price (expect to pay at least $30 / hour if you’re hiring an agency)
- Approach and particularities (technical SEO, link building, content optimization, etc.)
- Communication and reporting
