Kolkata, West Bengal, India, 12 October 2026 - OIESU (OPC), a digital marketing agency in Kolkata, has published a free guide to help service businesses choose between PPC and SEO, and to check an agency before signing. The guide can be read online here: https://online.fliphtml5.com/scomot/oiesu-ppc-seo-guide/

Pay-per-click (PPC) advertising places ads in front of people who are searching or browsing, and the business pays when someone clicks. It can bring enquiries within days of launch, but results stop when the spend stops. Search engine optimisation (SEO) aims to earn organic rankings in search results over time. It is usually slower, but well-built pages keep working without a fee for each click.

The guide lists questions to ask any provider: what they will measure (enquiries, calls, bookings or form submissions), who owns the landing page, which platform fits the audience, whether they understand the sector, what the written plan includes, and why no honest provider can guarantee a search ranking or a fixed number of leads.

OIESU offers SEO (https://oiesu.com/services/seo) and Google Ads management (https://oiesu.com/services/google-ads), along with Meta, Microsoft, LinkedIn and YouTube Ads, web design and landing pages. Visit https://oiesu.com/ for more information.
